Motor Ratings Data

Ampere Rating of AC and DC Motors

Ampere ratings of motors vary somewhat, depending upon

the type of motor. The values given below are for drip-proof,

Class B insulated (T Frame) where available, 1.15 service

factor, NEMA Design B motors. These values represent an

average full load motor current which was calculated from

the motor performance data published by several motor

manufacturers. In the case of high torque squirrel cage

motors, the ampere ratings will be at least 10% greater

than the values given below.

Caution — These average ratings could be high or low for

a speciﬁc motor and therefore heater coil selection on this

basis always involves risk. For fully reliable motor protection,

select heater coils on the basis of full load current rating as

shown on the motor nameplate.
