In our very last Productivity Forum, we concentrate on one of Nikola Tesla's most significant inventions — the ac motor. In this report, Motion System Design editors polled ac motor experts for advice ...

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.

Before putting an AC machine into service, make sure its duty rating matches the application requirements. Otherwise, there’s a good chance excessive heat will degrade the machine’s windings.
