in the occasion of any fault, fast achievement must be in
The breakdown of a synchronous motor has frequently a severe effect on the operation of a system. In some cases the breakdown results in vanished manufacture, even as in others it may expose human being security. In such applications it is advantageous to use a synchronous motor capable of continuing to operate in the occurrence of any single point breakdown. Such a synchronous motor is termed fault tolerant [3] and the development of a fault tolerant synchronous motor is the absolute mean of the research existing here.
use to avoid the faulted phase from illustration too much current or applying important braking torque to the shaft. fast fault detection is also main in the fault tolerant synchronous motor system, to allow correct situation fault stroke to be taken. Permanent Magnet Synchronous Motor (PMSM) are now broadly used in lots of manufacturing as applications require elevated system dependability, elevated efficiency and
