Determine the number of poles of this ac motor, Electrical Engineering

Assignment Help:

Q. A three-phase ac motor, used to drive a draft fan, is connected to a 60-Hz voltage supply. At noload, the speed is 1188 r/min; at full load, the speed drops to 1128 r/min.

(a) Determine the number of poles of this ac motor.

(b) Comment on whether this motor is an induction motor or a synchronous motor.
