Abstract :
Permanent magnet motors have been considered for a variety of applications due
to their features such as high power density and high efficiency. One of the issues that
should be investigated in the design of these motors is the demagnetization problem.
Usually, the demagnetization analysis is carried out in a steady state, while demagnetization
effect in dynamic condition is more considerable due to pulse shaped of armature field.
Based on this fact, in this paper, dynamic demagnetization is investigated for an IPM
V-shaped magnet. This study has been done for two types of magnet, each one in static &
dynamic conditions and the results are compared. Moreover, the effect of flux weakening
regime on demagnetization is investigated.
