The PSC motor uses a capacitor and has good running efficiency. When a PSC motor is used in compressors, it makes use of two capacitors attached to its wiring. The first one serves as a start ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Efficiency standards were once confined to integral horsepower motors but may soon apply to small motors and make certain kinds impractical to manufacture. Today, the electric motors that are of most ...
