The basic DC motor design is the same, that is, there is a stationary magnetic field structure and a rotating element. The rotating portion, the armature, is supported by a bearing structure. The field frame consists of a ferrous frame with coils to provide for magnetic coupling of flux to the armature. There are main coils in the field to provide the magnetics. Comm coils are also used. The armature has a shaft, coils to provide the magnetics to interact with the field coils, and a commutator. The commutator enables the coils on the rotating armature to be electrified. The brushes give a rotating connection between the armature and the power source. The bearings are supported by bearing brackets or endbells. The bearings themselves can be ball bearings, roller bearings, or sleeve bearings. Sleeve bearings can be Bronze or Babbitt. These basic elements are common to all DC motors. It is important to understand their relative positions when locating parts. There are also accessories which are added to the motor to improve performance, provide control data, and to protect the motor. 7–Medium DC For more information contact a GE Motor Parts Master Distributor or GE Support Services.

Today’s system has evolved from many years of experience. Learning from the past, it became quite clear to GE a system was needed to identify motor characteristics, ratings, and accessories with the model number alone. This system was first devised and implemented around 1970. An example of a model number would be 5CD194HA001A001. About 75% of our replacement requests are of this format. Another format for model numbers following this pattern: 5CD14D02A112003 5CD580G12AB These types of model numbers have been in use since about 1960 and are the second most frequent style seen on a daily basis representing about 15% of our requests. With these two types of model numbers, it is impossible to specify completely which motor is being requested without a serial number. About 5% of the replacement requests have model numbers with format: 33A1557 5B225A50 Every motor is also assigned a serial number which is unique to that motor. Serial numbers for GE DC motors are one of two forms depending on the date the motor was built. The years between 1930 and 1956, serial numbers took the form of a seven digit code. Theses generally look like this: 7283200 7079100 2355299 2164851 1839846 1590324 From about 1956 on to the present, serial numbers took the form of LL – N – NNN – LL where L = Letter and N = Number. These generally look like this: GC–1–510–LC LL–N–NNN–LL CK–1–1085–EK the first N is always one of the follow RE–1–471–RE 1, 2, or 8 AR–2–420–AR For parts identification, the last two letters are dropped from this format. For instance, GC–1–510 would be typed in for C–1–510–LC. 7–Medium DC Medium DC Motors Model Numbers Typical Format: 5CD NNN LL NNN L NNN . . . . . . . . . .

These make the unit unique. The base number, E.G. 5CD184TA001A, is the machine list, which list the field coils, armature, bearings, brushrigging, and so forth. Armature coils are found on the armature list on the machine list. MD800 motors are imputed with the 5MD dropped from the model. The last two letters indicate the ventilation and some other accessories. The basic number, without the 5MD and the two letter suffix has most of the data that is normally requested. When listing part numbers, always line the extension on the space 12, 13 and 14. For example: _ _ _ _ _ _ _ _ _ _ _ _ XXX XXX = appropriate group or part number. Serial numbers are entered with dashes. GE Support Services 7–Medium DC When having difficulty with a model: 1. drop 5 and impute, 2. drop 5 and first letter and impute, 3. drop 5 and first two letters and impute. In many cases, it is easier to inquire in the model list, E.G. 5CD184TA001A rather than the entire model number. 132 DC Motors Model Numbers Kinamatic II Design MODEL NUMBER PREFIX 7–Medium DC 5CD122 5CD123 5CD124 5CD125 5CD142 5CD143 5CD144 5CD145 5CD152 5CD153 5CD154 5CD163 5CD164 5CD173 5CD174 5CD183 5CD184 5CD192 5CD193 5CD194 5CD203 5CD203 5CD203 5CD204 5CD204 5CD204 5CD222 5CD222 5CD223 5CD223 5CD224 5CD224 5CD226 5CD362 5CD363 5CD372 5CD373 A B–R S–Y A B–R S–Y A–T,X,Y U–W A–T,X,Y U–W A–T,X,Y U–W CD4000 Line FRAME SIZE MODEL NUMBER PREFIX FRAME SIZE CD146 CD148 CD149 CD1412 CDL182AT CD186AT CDL186AT CD189AT CD218AT CD219AT CD2110AT CD258AT CD259AT CD287AT CD288AT CD327AT CD328AT CD365AT CD366AT CD368AT CDL407AT CD407AT CDL407AT CDL409AT CD409AT CDL409AT CD504AT CDL504AT CD506AT CDL506AT CD508AT CDL508AT CD5010ATZ CD2512AT CD2513AT CD2812AT CD2813AT 5CD431 5CD431 5CD432 5CD432 5CD433 5CD433 5CD434 5CD434 5CD435 5CD435 5CD442 5CD442 5CD443 5CD443 5CD444 5CD444 5CD445 5CD445 5CD446 5CD446 5CD453 5CD453 5CD454 5CD454 5CD455 5CD455 5CD456 5CD456 5CD463 5CD463 5CD464 5CD464 5CD465 5CD465 5CD466 5CD466 5CD473 5CD473 5CD474 5CD474 5CD475 5CD475 5CD476 5CD476 5CD477 5CD477 CD4350 CD4354 CD4352 CD4357 CD4355 CD4359 CD4358 CD4363 CD4362 CD4366 CD4454 CD4463 CD4457 CD4465 CD4460 CD4468 CD4464 CD4473 CD4469 CD4477 CD4559 CD4568 CD4562 CD4570 CD4566 CD4575 CD4571 CD4580 CD4670 CD4674 CD4673 CD4678 CD4677 CD4681 CD4682 CD4686 CD4773 CD4781 CD4776 CD4784 CD4780 CD4789 CD4785 CD4793 CD4791 CD4799 D–K L–N D–K L–N D–K L–N D–K L–N D–K L–N E–K L–N E–K L–N E–K L–N E–K L–N E–K L–N E–K L–N E–K L–N E–K L–N E–K L–N H–M N–R H–M N–R H–M N–R H–M N–R K–N P–T K–N P–T K–N P–T K–N P–T K–N P–T CD6000 Line MODEL NUMBER PREFIX 5CD601 5CD601 5CD602 5CD602 5CD603 5CD603 5CD604 5CD604 5CD605 5CD605 5CD612 5CD612 5CD613 5CD613 5CD614 5CD614 5CD615 5CD615 5CD616 5CD616 5CD623 5CD623 5CD624 5CD624 5CD625 5CD625 5CD626 5CD626 5CD673 5CD673 5CD674 5CD674 5CD675 5CD675 5CD676 5CD676 5CD683 5CD683 5CD684 5CD684 5CD685 5CD685 5CD686 5CD686 5CD693 5CD693 5CD694 5CD694 5CD695 5CD695 5CD696 5CD696 For more information contact a GE Motor Parts Master Distributor or GE Support Services.

Standard practice for oversized shafts and/or oversized ball bearings is to use the ball bearing size of the next larger frame (no oversized bearings or shafts available in CD5010AY frame). This chart does not apply to motors with roller bearings. Non–standards are manufactured for special applications. Therefore, not all Kinamatic motors follow the chart below. Refer to GE Support Services for non–standard motors.

A loose band will allow the coils to move and abrade, causing a short or ground. Proper tension should draw the coils to about one–third of the banding groove height. Under no circumstances should the tape rest on the bottom of the groove. Recommended absolute pressures for glass tape of the armature core: 3/8 wide 30 end 200–225 lbs. 3/4 wide 60 end 400–450 lbs. The armature should be preheated to 120˚C. The tension device must be able to maintain tape pressure when stopped. Bearings Grease–Generally used is GE D6A2C5, lithium soap base. Do not use grease with EP designation and do not mix greases. EP designated greases should not be used on DC motors. The additives work at elevated temperatures above the normal capability and the grease materials may deteriorate the winding insulation. Oil Leaks–Sleeve bearing housings are designed with vent passages to equalize air pressure on both sides of the bearing. Blockage of vents can cause oil leakage. Warning: Ensure all power has been removed from the machine before performing maintenance. To Replace Bearings– 1. First verify that the bearings are the problem. Symptoms may include contaminated oil, excessive vibration, noise, or heat. 2. Lubricate each bearing before installing: speeds below 1200 RPM use 300 SSU (Saybolt Seconds Universal) oil. Use 150 SSU oil for speeds above 1200 RPM. 3. Check for damaged seals and rings. Replacements are available from GE Support Services. Warning: Ensure all power has been removed from the machine before performing maintenance. Blower Impellers These will move air in either direction of rotation. Make sure that the rotation maximizes air flow. 7–Medium DC Blower Kit Modification –Comm end mount, F1 or F2, 230/460V, 3 Phase, 60 Hz. For other requirements, refer to GE Support Services. –CD180AT machines require drilling and tapping of mounting holes. –Check the direction of rotation of the impeller before placing motor into service. –Air flow may be reduced up to 30% due to accumulation of dirt on the impeller blades. –Maximum air rise through the machine is 25˚C. Brushholder Replacement Brush Box Height–Brush boxes are set .070–.080” above the commutator diameter on all GE Industrial DC motors, CD210AT–CD9000. Brushholder setting spacers are available through GE Support Services to ensure uniform height above the commutator: PT#36A178125AA001 for CD580AT–CD9000 PT#36A178125AA002 for CD210AT–CD500AT Cleaning brushholder springs by sand blasting may erode spring material changing the force constant and may introduce sand into the motor.Glass beading brushholder springs is acceptable. Warning: Ensure all power has been removed from the machine (e.g., lock out/tag out) before checking brush box heights.

The order of the shims is also important to maintain magnetic balance. The correct order of the shims, starting from the comm pole out is: 1. Thick steel shims (.125” thick) 2. Thick aluminum shims (.125” thick) 3. Thin aluminum shims 4. Thin steel shims The thin steel shims should rest against the frame. Field, Data – N/P volts = N/P current x N/P resistance x heat factor (1.39 Class F) (1.29 Class B) The field data listed on the nameplate with two field voltages assumes high voltage excitation. The field amps are listed for base speed and weak field speed. Resistance is given for series connection (one circuit) at 25˚C. If operating at low voltage (two circuit), field data must be adjusted. Multiply the field amps by two and divide the field resistance by four. All data is given hot, except the field resistance. Field, Main – Up to 110% excitation…within speed and load capability of the armature – Limit current to 50% maximum…armature at standstill or no blower use field economy relay – Resistance increase of 40% not uncommon from cold to hot Field, TREC Coils Bonding New Coils to Poles– 1. Note the vertical position of the original coil on the pole and the position of the leads. Repositioning coils exactly on the pole is critical to the machine performance. 2. When bonding new coils to poles, first travel bonding compound directly to the pole, ensuring adequate compound fills 100% of the space between the coil and pole. Center the new coil on the pole and position the coil as noted in Step #1. GE Support Services recommends EPC PREG X93C 1961 bonding compound, which can be purchased through Epic Resins at 1–800–242–6649. Recommended cure time is 6 hours at 165˚C. 3. Be sure to replace all magnetic pole shims in their original order. Warning: Ensure all power has been removed from the machine before performing maintenance.

Molded commutators have proven to be a reliable and stable design. The use of molded commutators is being expanded. Heating of the replacement commutator is not generally required for a successful installation. CD180AT –Comm is cemented to shaft, cold. CD210AT–CD320AT –Comm is furnished on an aluminum shell. Press on cold. CD360AT–CD500AT –Comm is furnished on a cast iron shell. Permissible to preheat to 150˚C to install. Caution: Avoid excessive/uneven heating. Motor Heating Rule of thumb is that the air rise through the motor should be a max of 25 degree C. The allowable ampere rating of a drip proof motor drops significantly at speeds less than 60%. See heating curves. 7–Medium DC Normal Environment – Temperature 0 to 40 degrees C (32 to 104 degrees F) – Humidity 40 to 99% – Altitude less than3300 feet – Loading 20 to 100% + occasional 150% current (100% base speed) occasional = 1 min or less, not part of regular duty cycle – Starting 250% full load current – CD180AT thru CD5010AT 300% full load current – CD4000 less than 10 seconds, not stalled Paint GE motors gray paint is a standard ASA#49.

Medium DC Motors 193 Maintenance Tips Sealant Silicone, RTV, or Bathtub Seal/Caulking is not recommended for sealing DC motors. The silicone compounds destroy brushes, use “Titeseal” sealing compound GE MOTORS #8064200000 Titeseal Titeseal is the preferred sealant used on waterproof motors to seal fits and bolts. It is non–hardening, non–silicone. GE#8064200000. Viton Protection Viton protection kit for glass bound commutators – protects new bands from contamination. Kit is part 36A173329AAG02. Apply two coats of DOLPH ER41 (not included) over Viton. DOLPH ER–41 This is the insulating enamel used for pole face connections.

MOTTLED SURFACE with random film pattern is probably the most frequently observed condition of commutators in industry. SLOT BAR–MARKING, a slightly darker film, appears on bars in a definite pattern related to number of conductors per slot. HEAVY FILM can appear over entire area of efficient and normal commutator and, if uniform, is quite acceptable. Watch for These Danger Signs 7–Medium DC STREAKING on the commutator surface signals the beginning of serious metal transfer to the carbon brush. Check the chart below for possible causes. THREADING of commutator with fine lines results when excessive metal transfer occurs. It usually leads to resurfacing of commutator and rapid brush wear. COPPER DRAG, an abnormal build–up of commutator material, forms most often at trailing edge of bar. Condition is rare, but can cause flashover if not checked. PITCH BAR–MARKING produces low or burned spots on the commutator surface. The number of these markings equals half or all the number of poles on the motor. x x HEAVY SLOT BAR–MARKING can involve etching of trailing edge of commutator bar. Pattern is related to number of conductors per slot. x x x x GROOVING is a mechanical condition caused by abrasive material in the brush or atmosphere. If grooves form, start corrective action. x x x x x x x x x x x x x x x x x x HOW TO GET THE MOST VALUE FROM THIS CHART The purpose of the Commutator Check Chart is to help you spot undesirable commutator conditions as they develop so you can take corrective action before the condition becomes serious. This chart will also serve as an aid in recognizing satisfactory surfaces. The box chart above indicates the importance of selecting the correct brush and having the right operating conditions for optimum brush life and commutator wear.

The copper and insulation segment pack has grooves machined between brush paths for application of high tension glass banding tape. This tape continually applies tension on the segment pack during service to maintain excellent stability at high speed. The shell consists of steel and covered with mica to provide ground insulation for the segment pack. An interference fit exists between the insulated shell and segment pack. Both open (separate piece) and closed (solid) risers are used. Band protection is provided by Viton (blue coating) to resist contamination that may attack bands. Solvent cleaning should not be used on commutators as contamination can be washed under the bands which could burn and deteriorate the bands from underneath which could lead to band failure.

Medium DC Motors 199 Commutators Cap and Cone or V–Ring This construction is typically used on smaller horsepower machines or ones specifically ordered for steel or papermill applications. The segment pack has “V” grooves machined into the ends. The inner clamping side has a thirty degree angle and outer clearance side a three degree angle. Mica cones insulate the segment pack from the steel shell and provide ground support. The steel clamp rings are held in tension by studs with nuts or long bolts. During manufacture, the commutator is pressed together and the studs tightened. While this construction is not as stable for high speed as a glass banded commutator, the design is a rugged one and repairability is often performed by users.

The copper segments have integral dovetails which are inserted into the steel shell with a matching dovetail. Mica insulation is then inserted between the copper segments and the segment pack is subjected to high circumferential pressure while epoxy compound is injected into the space between the shell and segment pack. The epoxy provides both the bond and ground insulation for the segment pack. The result is a very high quality commutator for high speed use. This commutator is used on the CD360–5010 motor line. EPOXY SHELL 7–Medium DC For more information contact a GE Motor Parts Master Distributor or GE Support Services. Medium DC Motors 201 Commutators Molded For cost purposes, the smallest machines use a molded style commutator. These machines are very standardized, high volume, and low cost. The copper and insulation pieces are normally punched out with a notch in the center. Following stacking , an epoxy compound is injected to form the shell. This commutator is not repairable and the design is cost effective and adequate for most small motor applications.
