Q&A about ac motors and induction motors
What is single phase AC motor?
Single phase induction engine is an AC motor were electricity is converted to mechanical energy to execute 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 really does an AC motor function single phase?
The stator of a single phase induction electric motor is wound with single phase winding. When the stator is definitely fed with an individual phase supply, it generates alternating flux (which alternates along one space axis just). Alternating flux functioning on a squirrel cage rotor can not produce rotation, just revolving flux can.
Can an individual phase motor run without a capacitor?
Single-phase induction motors are not self-starting without an 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 has a capacitor in series with it during starting and running.
How do you reverse a single phase motor?
Once started, a single phase induction motor will happily run in possibly direction. To reverse it, we have to change the path of the rotating magnetic field made by the main and starter windings. Which is achieved by reversing the polarity of the starter winding.
