Matching Data Needed:

HP = Horsepower

RPM = Rotations Per Minute—Sometimes listed as “number of poles”.

Ph = Phase—For AC motors the choice is “single” or “three” phase

Volts or V = Voltage—Common AC Voltages are 115/200/208/230/460

Fr = Frame—Examples include: 48 / 56/ 145T etc.

SF = Service Factor—Common SF = 1.0 / 1.15 / 1.25 / 1.35

Encl = Enclosure—Basic enclosures are “Open” or “Totally Enclosed”.

Rules of Thumb for Motor Replacement:

1. In HVAC, you can often move up to the next HP or move up in

Service Factor.

2. Matching Amperage can be helpful in estimating HP.

3. Ball and sleeve bearing motors can be inter-changeable, but ball

bearing may be noisier.

4. Motors can normally run up to 10% above and below rated voltage.

5. You should not interchange “Manual Overload” with an “Automatic

Overload” motor protector.

6. You can vary the speed of a PSC (Permanent Split Capacitor), but not

of a Split Phase or Capacitor Start Motor.

7. You can move up in “Starting” or “Run Torque”, when replacing a

motor. (e.g.: Cap Start can replace a Split Phase; PSC can replace

Shaded Pole.)

8. Motor Frame Diameter can be helpful in determining frame size.

9. TEAO or OAO enclosed motors need to be mounted in the air stream

of the fan they are running.

There are four types of single phase motors:

1. Shade Pole

2. Permanent Split Capacitor (PSC)

3. Split Phase

4. Capacitor Start

HOW TO REPLACE A MOTOR

Ideally, you should replace like for like, but that may not be always possible. Here are some basics:

Enclosures

Abbreviation Deﬁnition Description

OP Open Holes in motor shell

ODP Open drip-proof Bottom half of motor open (water will ﬂow out)

AO/OAO Air over/Open air over Fan air blows directly over motor

TE Totally enclosed No holes anywhere in motor shell

TEAO Totally enclosed air over Fan air blows directly over motor

TENV Totally enclosed non-vented Excess heat is radiated through the body of the motor

TEFC Totally enclosed fan-cooled Has an external fan covered by a housing

EXP-PRF Explosion proof Will withstand an explosion of a gas, vapor or dust, which may occur within it

*Air-Over motors (AO, OAO and TEAO) must have air blowing over them continuously while in operation.

Motor Dimensional Chart—All Dimensions in Inches

(*) Dimension “D” will never be greater than the above values on

rigid mount motors, but it may be less so that shims up to 1/32"

thick (1/16" on 364U and 365U frames) may be required for

certain machines.

(‡) Designated 56H motors have two sets of 2F mounting

holes—3" and 5".

(#) Discontinued NEMA frame.

(**) Base of Dayton 56HZ frame motors has holes and slots to

match NEMA 56, 56H and 145T mounting dimensions.

(†) Certain NEMA 56Z frame motors have 1/2" dia. x 11/2" long

shaft with 3/64" ﬂat. These exceptions are noted in this catalog.

(§) Dimension “V” is shaft length available for coupling, pinion or

pulley hub—this is a minimum value.

(§§) The 2F dimension is 20.

pages 4 thru 6 of the Grainger Catalog
