15 Questions
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.
How is the stator winding of a single phase induction motor arranged?
It is disposed in slots around the inner periphery of a laminated ring, similar to the 3-phase motor.
What type of rotor does an induction motor with a single phase stator winding usually have?
Squirrel cage rotor
What does the single winding on the stator of a single phase induction motor produce?
MMF stationary in space but alternating in time
How does the stator winding of a polyphase induction motor differ from that of a single phase induction motor?
The polyphase stator winding carries balanced currents producing rotating mmf in space, while the single phase stator winding produces alternating mmf in time.
Which type of motor has a stator winding that produces mmf rotating in space around the air gap and constant in time with respect to an observer moving with the mmf?
Polyphase induction motor
What type of rotor does an induction motor with a single phase stator winding usually have?
Squirrel cage rotor
In which motor is the actual stator winding distributed in slots to produce an approximately sinusoidal space distribution?
