Q&A about ac motors and single phase ac motor china induction motors
What’s single phase AC electric motor?
Single phase induction engine is an AC electric motor were electrical energy is changed into mechanical energy to execute some physical task. This induction electric motor requires only one power phase for their proper procedure. They are commonly found in low power applications, in domestic and industrial use.
How does an AC motor work single phase?
The stator of a single phase induction electric motor is wound with single phase winding. 
When the stator is fed with a single phase supply, it produces alternating flux (which alternates along one space axis only). Alternating flux functioning on a squirrel cage rotor cannot produce rotation, only revolving flux can.
Can a single phase motor run without a capacitor?
Single-phase induction motors are not self-starting without an auxiliary stator winding driven by an away of phase current of near 90°. Once started the auxiliary winding is usually optional. The auxiliary winding of a permanent split capacitor motor has a capacitor in series with it during starting and running.
How can you reverse an individual phase motor?
Once started, a single phase induction motor will certainly happily run in possibly direction. To invert it, we need to change the direction of the rotating magnetic field produced by the main and starter windings. Which is achieved by reversing the polarity of the starter winding.
