Synchronous motors have a stationary magnetic field relative to the rotor. Permanent magnets or field windings through slip rings create the field. Induction motors have a rotating magnetic field ...

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 ...

Electric motors consume almost half of the electricity produced worldwide. They, in fact, provide the necessary driving force for much of today’s equipment. Motors, pumps, and fans are present in an ...

The power of a synchronous motor depends directly on the load angle: the greater the load angle, the more torque, which determines the power by the speed specified by the input gear and the ...

The discussion to use AC induction motors or permanent magnet motors has two faces. On the one hand we have to look on efficiency, weight and size. But as well we have to recognize the international ...

A compact wireless data acquisition system can investigate, monitor and optimise electric rotor motor operation, say Rolf Spellmeyer and Diego Llopis. In modern electric vehicles, different types of ...
