Dynamic Permanent Magnet Flux Estimation of Permanent Magnet Synchronous Machines

IEEE Transactions on Applied Superconductivity, 2010
This paper deals with rotor flux estimation in permanent magnet synchronous motor(PMSM). In most application, the rotor flux linkage is treated as a known constant. However a high operation temperature or a stator winding current impulse may cause magnet flux ripple or demagnetization which has direct impact on machines performance.

Study on Permanent Magnet Demagnetization Characteristics in Permanent Magnet Synchronous Machines

Advanced Materials Research, 2011
When Permanent Magnet Synchronous Machines (PMSM) working with rated load or overload, stator iron loss and copper loss, bearings friction loss, permanent magnet (PM) eddy-current all will cause PM temperature rise. In this condition, the PM is affected by the temperature and the stator of the reverse magnetic field generated prone to arouse ...

Permanent-Magnet Machines

2015
Being fueled by continual development of permanent-magnet (PM) materials and machine structures, PM machines are becoming attractive for a wide range of applications. In this article, the magnet-materials that have been used for PM machines are first introduced. Then, the classification of various PM machines is discussed.
