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.

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...
