Q&A about ac motors and induction motors
What’s single phase AC motor?
Single phase induction motor is an AC engine 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 found in low power applications, in household and industrial use.
How will an AC motor function single phase?
The stator of a single phase induction motor is wound with single phase winding. When the stator is usually fed with an individual phase supply, it produces alternating flux (which alternates along one space axis only). Alternating flux acting on a squirrel cage rotor can not produce rotation, just revolving flux can.
Can a single phase motor run with out 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 certainly optional. The auxiliary winding of a long term split capacitor motor has a capacitor in series 
with it during beginning and running.
How can you reverse a single phase motor?
Once started, an individual phase induction motor will happily run in either direction. To invert it, we have to change the path of the rotating magnetic field made by the primary and starter windings. Which is achieved by reversing the polarity of the starter winding.
