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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

The squirrel cage induction motor's versatility and ruggedness continue to make it the workhorse of the industry, but that doesn't mean it's invincible. Pushing it too hard for too long can cause the ...

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.

Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses ...

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 AC induction motor (ACIM) is the most popular motor used in consumer and industrial applications. The motor is highly reliable, as its simple design has no brushes that could wear out, and it can ...
