The 4-pole AC motor is the largest part of the AC motor market because it is versatile, energy-efficient, and has a lot of applications in various types of industries such as HVAC, pumps, and ...

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.

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...
