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