SUMMARY
Single phase AC motors utilize two inductors to generate a rotating magnetic field, with one inductor connected to a capacitor to alter the phase angle. While single phase motors can operate with only one winding powered, they typically require an auxiliary winding for starting. The shaded pole motor is a notable example of a single phase motor that operates with just one coil. The discussion also explores the potential use of diodes for controlling the inductors' operation, but concludes that this approach is impractical due to the nature of AC current and inductive energy storage.
