Q&A about ac motors and induction motors
What is single phase AC electric motor?
Single phase induction electric motor is an AC motor were electricity is changed into mechanical energy to perform some physical task. This induction electric motor requires only 1 power phase because of their proper operation. They are commonly used in low power applications, in household and industrial use.
How does an AC motor work single phase?
The stator of an individual phase induction motor is wound with single phase winding. When the stator is certainly fed with a single phase supply, it generates alternating flux (which alternates along one space axis only). Alternating flux functioning on a squirrel cage rotor cannot produce rotation, just revolving flux can.
Can a single phase motor run with out a capacitor?
Single-phase induction motors are not self-starting lacking any auxiliary stator winding driven by an out of phase current of near 90°. Once started the auxiliary winding is usually optional. The auxiliary winding of a long lasting split capacitor motor includes a capacitor in series with it during starting and running.
How do you reverse a single phase motor?
Once 
started, an individual phase induction motor can happily run in either direction. To reverse it, we have to single phase ac motor china change the direction of the rotating magnetic field produced by the primary and starter windings. And this can be achieved by reversing the polarity of the starter winding.
