The Analysis and Simulation of the Armature Magnetic Field in Coreless Permanent Magnet Synchronous Motor

摘要

Disc coreless permanent magnetic synchronous motor (PMSM) is a new permanent magnetic motor. It has many advantages, such as little volume, low mass, low lost, high power density etc. It gradually becomes the good choice in drive system. Its structure is introduced in this paper. The techniques of armature winding and the arrangement of permanent magnetic disc are emphasized. A calculation's model of the armature magnetic field was established. The armature magnetic field in the motor is computed and analyzed with finite element method (FEM). And the influence of the armature magnetic field to the main field is discussed.
