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 ...

In applications demanding precision and throughput, linear motor production systems usually need to be built from the ground up. Fractional microns accuracy requires feedback from an optical encoder, ...

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

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.

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 ...
