doi:10.11985/2017.01.003

Abstract

Abstract:

The performance targets of PMSM are prominent, compared to other type motors, PMSM are widely used in various fields. With the development of the motor manufacturing industry, the motor capacity increases, resulting in increasing temperature of inside the motor, the high temperature severely affected performance and reliable operation of motor. In this paper, in consideration of the influence of the permanent magnet eddy current loss of high speed motor on the temperature field, thermal analysis using LPTN in PMSM, the thermal network model of 38 nodes is established. truly reflect the temperature rise of each part of the motor. Finally, the correctness of the model is verified by comparison with the results of finite element method (FEM) and temperature rise test.

Key words: Permanent magnet synchronous motor, temperature field, lumped parameter thermal network, finite element method
