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 ...

The increasing importance of energy efficiency has brought electric motor makers to promote a variety of schemes that improve motor performance. Unfortunately the terminology associated with motor ...

This advanced variant of a separately excited synchronous motor is thus an alternative to permanent-magnet synchronous machines (PSM). New Delhi: ZF has developed an electric motor which does not ...

Permanent magnet synchronous motors are up to 15 per cent more efficient than induction motors and are the most power-dense type of traction motor commercially available. New Delhi: Growing demand of ...
