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 ...

Small and medium AC induction motors account for more than 75% of motor electrical energy demand; however, they typically receive less maintenance than their larger counterparts. This leaves them ...

In this single phase induction motor, energy from the primary winding in yellow is coupled through a magnetic core to a rotary structure called a bobbin, which acts as a short circuited transformer ...

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 ...

Energy makes up 80 percent of the cost of owning and operating a motor over its lifespan. That’s why motor makers have spent decades trying to build ever more energy-efficient designs. But with ...
