Abstract:

Integrated-starter-generator (ISG) motors are a key part of new-energy vehicle dynamic systems. To more efficiently design higher-performance permanent magnet ISG motors, we proposed a multiphysical-domain integrated design method by designing the electromagnetism and thermal performance of motors and the mechanical structure strength of rotors together. A 48-slot and 8-pole oil-cooled permanent magnet ISG motor was designed by using this method and simulated via the finite element method. Also, a motor-testing platform was built to experimentally validate this method. The simulation results were consistent with the test results, which confirmed that the new method was accurate and effective and can be referred to during the practical design and development of high-density permanent magnet motors.
