Q&A about ac motors and induction motors
What is single phase AC electric motor?
Single phase induction motor is an AC motor were electricity is changed into mechanical energy to execute some physical task. This induction electric motor requires only one power phase for his or her proper procedure. They are commonly used in low power applications, in household and industrial use.
How does an AC motor function single phase?
The stator of an individual phase induction motor is wound with single phase winding. When the stator is fed with an individual phase supply, it creates alternating flux (which alternates along one space axis only). Alternating flux acting on a squirrel cage rotor cannot produce rotation, only 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 definitely optional. The auxiliary winding of a long lasting split capacitor motor has a capacitor in series with it during beginning and running.
How do you reverse an individual phase motor?
Once started, a single phase induction motor will certainly happily run in possibly direction. To invert it, we have to change the direction of the rotating magnetic field produced by the main and starter windings. And this can be accomplished by reversing the polarity of the starter 
winding.
