Permanent Magnet Synchronous Motors (PMSM). Parameters influence on the synchronization Process of a PMSM

Abstract

This   paper    deals    with    the   finite    element estimation  of  cogging  torque  oscillations  that  occur  in  multi-pole permanent magnets synchronous wind generators.  The  numerical analysis  is  carried  out  using a  2D  plane-parallel finite  element  model  of  the  machine  and  afterward  a  more elaborated  3D  model  able  to  take  into  account  the  skewing  of the   stator   slots.   The   numerical   results   are   discussed   and compared with the experimental measurements. This  paper  presents  also  the  influence  of  the  magnetization characteristics of stator and rotor cores as well as the influence of  the  magnetization  orientation  of  the  permanent  magnets  of the generator on the cogging torque values.
