Shaded pole induction motor is usually ________ in efficiency, and built ________ HP
Right Answer is:
Low, around 1/20 to 1/2
Shaded-pole motors are best suited to the low-power household application because the motors have low starting torque and efficiency ratings. Because of the weak starting torque, shaded-pole motors are built only in small sizes ranging from 1/20 to 1/6 hp.
