Permanent Magnet Motor for Electric Dynamometer
Introduction
- The characteristics of permanent magnet synchronous motor are
similar to those of traditional electrically excited synchronous
motor
- The permanent magnet replaces the excitation system on its rotor
- The structure of the motor is relatively simple, the processing and
assembly costs are reduced, and the
- The collector ring and brush that are easy to cause problems
improve the reliability of motor operation;
- No excitation current is needed, the excitation loss is saved, and
the efficiency of the motor is improved
- And power density.
- Therefore, it is a kind of motor which has been studied more and
more in recent years and has been more and more widely used in
various fields
