转子风刺对高速永磁电机永磁体温升的抑制作用
Suppression Effect of Rotor Wafters on Permanent Magnet Temperature Rise for High-speed Permanent Magnet Motor
摘要
Abstract
In order to study the influence of rotor wafters on internal fluid flow and temperature distribution for high speed permanent magnet motor(HSPMM),a 15 kW,30000r/min high-speed permanent magnet motor was taken as an example.On the basis of computational fluid dynamics(CFD) and heat transfer theory,the computation model of fluid and temperature field was established,and calculated using finite volume method by giving fundamental assumptions and corresponding boundary conditions.The temperature distribution of each part and air flow characteristics in the motor with and without wafters were obtained.Then,the influence of different wafter length and number on fluid and temperature field were studied.The calculated results show that the temperature rise of permanent magnet is reduced effectively by adding reasonable wafter,which provides certain guidance for improving heat dissipation capacity of HSPMM.At last,temperature rise test for a water-cooling 10 kW permanent magnet motor was conducted,and the test data were compared with the calculated results,which validates the correctness of the coupled field computing method adopted in this paper.关键词
