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.

Most industrial ac motors are three-phase designs that are at least 60% more efficient than single-phase motors, with excellent speed-control potential. In controlling this range of motors, your ...

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...
