HANDLING THE LINEAR SERVO MOTOR
Structure of the linear servo motor
The linear servo motor consists of a primary side made up of an iron core and coil and a secondary side made up of a mounting part (yoke) and a permanent magnet. (excluding coreless type LM-U2 series)
Primary side
Laminated core

Molded resin Molded resin or stainless steel cover

Motor coil

Permanent magnet

Secondary side

Mounting part (yoke)

Primary side
The primary side contains a magnet wire wound around the iron core of the motor and is covered with molded resin.
Secondary side
The secondary side has a permanent magnet on the mounting part (yoke) and is protected with molded resin or a stainless steel cover.

Magnetic attraction force
The secondary side of the linear servo motor contains a strong permanent magnet, so a magnetic attraction force (the force by which a magnet attracts magnetic materials) is generated toward magnetic materials such as iron. This magnetic attraction force is always generated regardless of whether the linear servo motor power is on/off.
Always acting regardless of on/off of the power

Magnetic attraction force

Magnet side face

Mounting part (yoke) side face

The magnetic fluxes generated by the permanent magnet are dispersed into the air from the magnet face side (the side facing the primary side), and most of said fluxes do not leak to the mounting part (yoke) surface side due to its structure. Because of this, the magnetic attraction force occurs on the magnet face side of the secondary side, not on the mounting part (yoke) surface side.

Mounting part (yoke)

Mounting part side face...No dispersion of magnetic fluxes

Not generating magnetic attraction force
The permanent magnet used for the linear servo motor is very strong. When an A4-sized iron sheet is fully attracted, the magnetic attraction force becomes as high as 2.5 t. Exercise sufficient caution when handling the product. Magnetic attraction force  400 [kPa]

If an A4-size iron sheet is fully attracted

A4 (21 � 29.7 cm)

Approx. 2.5 t

For safety
The magnetic attraction force is in inverse proportion to the square of the distance between magnetic materials, and said force drastically increases when the distance becomes small. When mounting the secondary side of the linear side motor, ensure that the distance from nearby magnetic materials is sufficient and securely fix said magnetic materials into place. If a problem is suspected with the product, stop using it immediately.

1.3 Design instructions
Precautions
� Although a dynamic brake can be applied by the servo amplifier, the coasting distance becomes longer when the mass of the moving part is heavy or when the speed is high. This is highly dangerous and may result in a collision into the stroke end. Install an anti-collision mechanism such as an air brake or an electric/mechanical stopper such as a shock absorber to reduce the shock of moving parts. (No linear servo motor with an electromagnetic brake is available.)
� The magnetic attraction force operating between the primary and secondary sides is always in operation even when the linear servo motor power is not turned on. As such, the machine must be designed with sufficient rigidity to support the magnetic attraction force and maintain the accuracy.
� Since the running load increases in proportion to the magnetic attraction force due to friction, arrange to reduce friction as much as possible by precisely installing the linear guide, etc.
� When the liner servo motor is used on a vertical axis, provide a drop prevention system to prevent free fall at servo-off by using a spring or a counter balance.
� Install the linear servo motor so that the thrust operates on the center of gravity of the moving part. When the thrust does not operate on the center of gravity of the moving part, a moment occurs.
� If magnetic powders such as iron shavings are present, they may stick to the permanent magnet on the secondary side and cause a malfunction. In such an environment, take measures to prevent the adhesion and entry of magnetic powders.
� While both the linear encoder and the linear servo motor should be oil and dust proofed, oil and dust proofing are especially important for the linear encoder. For details, contact the manufacturer of the linear encoder being used.
� Do not allow the primary side to come into contact with the stopper. Doing so may damage the primary side. Arrange the system so that only the table attached to the primary side comes into contact with the stopper.
� Do not use the screw holes of the linear servo motor for any purpose other than for machine installation. � For installation, use all of the screw holes provided on the linear servo motor. � If it is assumed that a power failure or product malfunction may result in a hazardous situation, provide an external brake
system for holding purposes to prevent such hazards. � Provide adequate protection to prevent an unexpected restart after an instantaneous power failure. � Arrange for the primary and secondary side to satisfy the mounting dimensions. � When using a linear guide as the base, check the specifications and determine the processing accuracy. For details,
contact the manufacturer of the linear guide being used. � The movable range of the linear servo motor should be equal to or less than the effective measurement length of the linear
encoder. � For the stopper, use shock-absorbing material such as polyurethane rubber. � Conditions where cutting fluid or lubricating oil are constantly applied or where condensation occurs for an extended period
of time due to the effects of oil-mist lubrication, over-cooling, or excessive humidity may result in the deterioration of the insulation on the linear servo motor. Provide measures such as oil proofing, a dust proof cover, or condensation prevention to protect the linear servo motor. � Consider the installation work when designing the system. For details of installation, refer to the following and the "Installation" section in the chapter for the linear servo motor series being used. Page 15 Instructions on installation � For high-accuracy positioning, ensure that the rigidity of the machines has been maximized and increase the mechanical resonance points. � To ensure that the rigidity of the machines is maximized, adopt an integrated structure for the base. When it is necessary to use bolts, etc. as a fastener, use thick bolts with short neck dimensions. Make the pitch dimension of bolt holes as small as possible. � Make the moving parts as light as possible, and make the base parts heavy and sturdy. � When loading works, etc. on the table, make the center of gravity as low as possible. Additionally, the position of the center of gravity should be between the two linear guides. � Since the movement or accuracy of the machine may be adversely affected, arrange for the center of thrust of the linear servo motor and the center of gravity of the moving object to be closer with one another.

� When the mounting rigidity of the linear encoder is insufficient, the feedback signal may be disturbed by the machine

vibration, and the desired performance may not be achieved. Furthermore, as the same condition also applies in cases

where the linear encoder is susceptible to electric noise, arrange or install the linear encoder in a way that minimizes

1

exposure to vibration and electric noise.

� Establish a structure that can withstand high speeds and high acceleration/deceleration.

1.4 Instructions on installation 1
Instructions on the use of lifting machines such as cranes when installing the linear servo motor are shown below.
Precautions
� The cables should not be damaged, stressed, loaded, or pinched. � Install the linear servo motor on incombustible material. Installing the linear servo motor either directly on or near
combustibles may lead to smoke or a fire. � Provide adequate protection so as to prevent conductive matter (such as screws and metal fragments) and combustible
matter (such as oil) from entering the linear servo motor. � The linear servo motor may become hot depending on the operating method. Take safety measures such as providing
covers. � Machine operators and workers installing linear servo motors are not allowed to wear or carry electronic devices (such as
watches, calculators, and personal computers) and carry magnetic recording media (IC cards, magnetic cards, floppy disks, etc.) when working close to the secondary side. The magnetic effect of such items may cause operation failure or malfunction. � Securely fix the linear servo motor to the machine. If attached insecurely, the motor may come off during operation. � Do not overtighten the eyebolts of the linear servo motor. Tightening too hard may damage the tap. � Do not stack in excess of the specified number of product packages. � Do not carry the linear servo motor by the cables or connectors. Doing so may damage the linear servo motor. � When installing the linear servo motor, follow the user's manual and install the motor in a place that can support its weight. � When installing the secondary side, use non-magnetic tools. � Securely fix the linear servo motor to the machine. If attached insecurely, the motor may come off during operation. � The travel direction of the linear servo motor and the linear encoder must match. Failing to do so may cause the linear servo motor to operate unexpectedly. � To prevent a connection failure, malfunction, or similar problem, do not strike the connector. � Use the product within the specified environment. For details of the environment, refer to the specifications for the linear servo motor series being used. � To prevent rust, do not touch the linear servo motor with bare hands. � The primary side and secondary side of the linear servo motor may be damaged if they are dropped or struck. � Do not install or operate a servo amplifier or linear servo motor that is missing parts or is damaged. � The permanent magnet on the secondary side of the linear servo motor generates a magnetic attraction force against magnetic materials. Therefore, individuals using a medical device such as a pacemaker must check with the medical device manufacturer regarding whether they can work in such an environment. � When in the original packing state (inside the cardboard box) that it was in when shipped from Mitsubishi Electric, the magnet on the secondary side does not have any serious impact on the outside environment. However, do not place magnetic materials (including the primary side, other secondary sides, and tools) close to the secondary side until the linear servo motor is assembled to the machine. Be cautious in the workplace and its surroundings. � When installing the linear servo motor and working near the linear servo motor, use non-magnetic tools. Such tools are necessary to ensure safety and improve workability. In particular, exercise care when installing the primary side after installation of the secondary side is complete. For which screws to use, refer to the "Dimensions" section in the chapter for the linear servo motor series being used. � Do not get on the equipment or put a heavy load on it. � Do not drop or strike the linear servo motor. � To prevent a fire or injury from occurring in case of an earthquake or other natural disasters, securely install, mount, and wire the linear servo motor in accordance with the user's manual. � To prevent an electric shock or a fire, do not disassemble, repair, or modify the product. Disassembled, repaired, and/or modified products are not covered under warranty. � Keep the cumulative pitch error of the mounting screw holes to within �0.2 mm (�0.1 mm for the LM-K2 series). When two or more secondary sides are installed, clearance may be left between the secondary sides depending on the installing method and the number of secondary sides.

5.3 Derating

For the reference values shown, derating is performed from the rated speed. As the temperature rise value of the linear servo motor changes depending on operation conditions such as speed, confirm that [AL. 0E2 Servo motor overheat warning] and [AL. 046 Servo motor overheat] do not occur on the actual machine before use. If a warning or alarm occurs, consider taking the following measures: � Lower the effective load ratio of the linear servo motor. � Review the heat dissipation conditions. To use this product under conditions with multiple derating, calculate the multiplication of each derating rate, and use at the calculated derating rate or lower.

Installation of the secondary side (magnet)
Precautions
� If mounting an additional secondary side with a secondary side already set, first set the additional side so that it is distanced from the already mounted one, then slide the additional side to mount it in its specified position as shown in this section.
� Keep the cumulative pitch error of the mounting screw holes to within �0.2 mm. When two or more secondary sides are installed, clearance may be left between the secondary sides depending on the installing method and the number of secondary sides.
Procedure
When using multiple secondary sides, arrange them so that the name plate attached to each side all share the same orientation to keep the layout of magnetic poles.
Plate
In addition, use the following procedure when mounting the secondary sides to decrease the clearance between them.
1. Use bolts to securely fix the secondary side that will be used as the mounting standard into place.
Secondary side to be a mounting standard
2. Set the next secondary side on the mounting face and use bolts to temporarily fix it into place.

Installation of the primary side (coil)
Precautions
� We recommend mounting the primary side in a position where no secondary side is present. If the primary side must be mounted over the secondary side, use material handling equipment such as cranes that can fully withstand the load of the attraction force, etc.
� When sliding the primary side over the secondary side after installing, take precautions against the attraction force that is generated.
Procedure 1. Mount a portion of the secondary sides.

2. Mount the primary side in a position where no secondary side is present.

5

3. Move the primary side over the mounted secondary side. Confirm that the primary and secondary sides are not touching
each other.

4. Mount the rest of the secondary sides. Confirm that the primary and secondary sides are not touching each other.

5.5 Dimensions

Primary side (coil) dimensions
� The recommended tightening torque for mounting screws on the primary side is 7.0 N�m (permissible range: 6.0 N�m to 7.8 N�m).
� The power lead wires, grounding lead wires, and thermistor lead wires are for fixed wiring. Securely fix them to the structure. The recommended minimum bending radius for the lead wire is six times or more (reference value) the standard overall diameter of the lead wire. Consider the speed of the linear servo motor and the flexing radius when selecting the cable to use for the moving part.
� Leave 2 mm or more on each side of the clearance between the side face of the primary side and the structure.

6.3 Derating

For the reference values shown, derating is performed from the rated speed. As the temperature rise value of the linear servo motor changes depending on operation conditions such as speed, confirm that [AL. 0E2 Servo motor overheat warning] and [AL. 046 Servo motor overheat] do not occur on the actual machine before use. If a warning or alarm occurs, consider taking the following measures: � Lower the effective load ratio of the linear servo motor. � Review the heat dissipation conditions. To use this product under conditions with multiple derating, calculate the multiplication of each derating rate, and use at the calculated derating rate or lower.

Installation of the secondary side (magnet)
Precautions
� If mounting an additional secondary side with a secondary side already set, first set the additional side so that it is distanced from the already mounted one, then slide the additional side to mount it in its specified position as shown in this section.
� Keep the cumulative pitch error of the mounting screw holes to within �0.2 mm. When two or more secondary sides are installed, clearance may be left between the secondary sides depending on the installing method and the number of secondary sides.
Procedure
When using multiple secondary sides, arrange them so that the caution plate attached to each side all share the same orientation to keep the layout of magnetic poles.
Caution plate
6
In addition, use the following procedure when mounting the secondary sides to decrease the clearance between them.
1. Use bolts to fix the secondary side that will be used as the mounting standard into place.
(Secondary side to be a mounting standard)
2. Set the next secondary side on the mounting face and use bolts to temporarily fix it into place.
(Secondary side to be a mounting standard)
3. Press the added secondary side toward the secondary side that is being used as the mounting standard.
(Secondary side to be a mounting standard)
4. Use bolts to securely fix the added secondary side into place.

Installation of the primary side (coil)
1. Mount a portion of the secondary sides.
2. Mount the primary side in a position where no secondary side is present.
3. Move the primary side over the mounted secondary side. Confirm that the primary and secondary sides are not touching
each other.
4. Mount the rest of the secondary sides. Confirm that the primary and secondary sides are not touching each other.

6.5 Dimensions

Primary side (coil) dimensions

When mounting the primary side, use hexagon socket head cap screws (material should be SUS304 with a lower yield point of 206 N/mm2 or equivalent and a fitting screw length of 4 mm or more). The power lead wires, grounding lead wires, and thermistor lead wires are for fixed wiring. Securely fix them to the structure. The recommended minimum bending radius for the lead wire is six times or more (reference value) the standard overall diameter of the lead wire. Consider the speed of the linear servo motor and the flexing radius when selecting the cable to use for the moving part. When mounting the primary side on the secondary side, make adjustments so that the gap can be secured.

7.3 Derating

For the reference values shown, derating is performed from the rated speed. As the temperature rise value of the linear servo motor changes depending on operation conditions such as speed, confirm that [AL. 0E2 Servo motor overheat warning] and [AL. 046 Servo motor overheat] do not occur on the actual machine before use. If a warning or alarm occurs, consider taking the following measures: � Lower the effective load ratio of the linear servo motor. � Review the heat dissipation conditions. To use this product under conditions with multiple derating, calculate the multiplication of each derating rate, and use at the calculated derating rate or lower.

Installation of the secondary side (magnet)
Precautions
� If mounting an additional secondary side with a secondary side already set, first set the additional side so that it is distanced from the already mounted one, then slide the additional side to mount it in its specified position as shown in this section.
� Keep the cumulative pitch error of the mounting screw holes to within �0.2 mm. When two or more secondary sides are installed, clearance may be left between the secondary sides depending on the installing method and the number of secondary sides.
Procedure
When using multiple secondary sides, arrange them so that the name plate attached to each side all share the same orientation to keep the layout of magnetic poles.
Plate

In addition, use the following procedure when mounting the secondary sides to decrease the clearance between them.
1. Use bolts to securely fix the secondary side that will be used as the mounting standard into place.

Installation of the primary side (coil)
Precautions
� We recommend mounting the primary side in a position where no secondary side is present. If the primary side must be mounted over the secondary side, use material handling equipment such as cranes that can fully withstand the load of the attraction force, etc.
� When sliding the primary side over the secondary side after installing, take precautions against the attraction force that is generated.
Procedure 1. Mount a portion of the secondary sides.
2. Mount the primary side in a position where no secondary side is present.
3. Move the primary side over the mounted secondary side. Confirm that the primary and secondary sides are not touching
each other.
4. Mount the rest of the secondary sides. Confirm that the primary and secondary sides are not touching each other.

7 LM-F SERIES 7.4 Installation

7.5 Liquid cooling

LM-F series linear servo motors are compatible with liquid cooling. Configure the machine (system) after confirming the

following items.

� Parts required for cooling system design, including the cooling pipe laying in the primary side table, parts required for

installation and cooling, the cooling machine (chiller), and the coolant should be carefully selected by the customer. For

example, when water is used as coolant, 5 liters or more are required per minute. Ensure that the pressure on the pipe flow

entrance is 0.5 MPa or less.

� To prevent foreign matter from entering the cooling pipe, be sure to always set a filter, etc. in the flow path.

� To avoid a liquid leak, the liquid-cooling pipe, coupling, etc. should be carefully selected by the customer. In particular, be

sure to select a liquid-cooling pipe that can withstand being bent.

� We recommend keeping the temperature of the liquid injected into the cooling pipe at room temperature (around 20 �C).

Ensure that condensation does not occur if lowering the liquid temperature to heighten the cooling effect.

� The overload protection characteristics are different from those for natural cooling, so confirm that conditions such as the

operation pattern are matched with the overload protection characteristics. If the operation conditions are not matched with

the overload protection characteristics, an alarm may occur. For the overload protection characteristics, refer to "USING A

LINER SERVO MOTOR" in the following manual. MR-J5 User's Manual (Hardware)

� Copper is used as the material for the cooling pipe, so when choosing the corrosion inhibitor to add to the coolant, be sure

to select one that will not corrode the copper. � When laying the cooling pipe, fix the hexagonal part of the cooling pipe in place using a spanner. The tightening torque

7

used should be 3.0 N�m to 3.5 N�m.

7.6 Dimensions

Primary side (coil) dimensions

When mounting the primary side, use hexagon socket head cap screws (material should be SCM435 with a lower yield point of 900 N/mm2 or more). The power lead wires, grounding lead wires, and thermistor lead wires are for fixed wiring. Securely fix them to the structure. The recommended minimum bending radius for the cable is six times or more (reference value) the standard overall diameter of the cable. Consider the speed of the linear servo motor and the flexing radius when selecting the cable to use for the moving part.

8.3 Derating

For the reference values shown, derating is performed from the rated speed. As the temperature rise value of the linear servo motor changes depending on operation conditions such as speed, confirm that [AL. 0E2 Servo motor overheat warning] and [AL. 046 Servo motor overheat] do not occur on the actual machine before use. If a warning or alarm occurs, consider taking the following measures: � Lower the effective load ratio of the linear servo motor. � Review the heat dissipation conditions. To use this product under conditions with multiple derating, calculate the multiplication of each derating rate, and use at the calculated derating rate or lower.

Installation procedure
Precautions
� If mounting an additional secondary side with a secondary side already set, first set the additional side so that it is distanced from the already mounted one, then slide the additional side to mount it in its specified position as shown in this section.
� After installation, confirm that the primary side is not touching the secondary side. � Keep the cumulative pitch error of the mounting screw holes to within �0.1 mm. When two or more pairs of secondary sides
are installed, clearance may be left between the secondary sides depending on the installing method and the number of secondary sides.
Procedure 1 1. Place one half of the first pair of secondary sides on the stage. 2. Firmly press the side face of the secondary side against the stage, then securely fix it into place with hexagon socket
head cap screws.
Secure the secondary side with the hexagon socket head cap screw.

8.5 Dimensions

Primary side (coil) dimensions

When mounting the primary side, use hexagon socket head cap screws (material should be SCM435 with a lower yield point of 900 N/mm2 or more). The power lead wires, grounding lead wires, and thermistor lead wires are for fixed wiring. Securely fix them to the structure. The recommended minimum bending radius for the lead wire is six times or more (reference value) the standard overall diameter of the lead wire. Consider the speed of the linear servo motor and the flexing radius when selecting the cable to use for the moving part.
