What is the main difference between a single phase induction motor and a polyphase induction motor?

The single phase motor has a single winding on the stator producing alternating mmf in time, while the polyphase motor has a stator winding carrying balanced currents producing rotating mmf in space. (correct)

The single phase motor has a rotor with a squirrel cage, while the polyphase motor has a different type of rotor.

The single phase motor has a polyphase stator winding, while the polyphase motor has a single winding on the stator.

The single phase motor has multiple windings on the stator, while the polyphase motor has only one winding.

How is the stator winding of a single phase induction motor arranged?

It is distributed in slots to produce an approximately sinusoidal space.

It is connected directly to the rotor for better efficiency.

It is disposed in slots around the inner periphery of a laminated ring, similar to the 3-phase motor. (correct)

It is wound around the rotor to produce a strong magnetic field.

What type of rotor does an induction motor with a single phase stator winding usually have?

Squirrel cage rotor (correct)

Cylindrical rotor

Slip ring rotor

Wound rotor
