Split-phase, capacitor, and shaded-pole single-phase motors classified as:

• A. A.C. series motors
• B. Repulsion motors
• C. Un-excited synchronous motors
• D. 1-phase induction motors

Answer: (D)

Split-phase, capacitor, and shaded-pole single-phase motors classified as single phase motor.
The single-phase motor with a single winding is not self-starting, because if the single winding is fed with a.c., it simply produces a “pulsating field” which rises and falls with the alternating current, and this type of field produces no torque in the rotor.
