摘要

Traction Motor is the key component of hybrid vehicles and have big influence on function and performance of the vehicle. In this paper, a compact, reliable and high-performance permanent magnetic synchronous motor(PMSM) is developed, which is the key part of a clutch coupling motor(CCM) module used for hybrid vehicles. During the concept design phase, considering about the special boundaries and requirements of motor for CCM, a 20-pole/30-slot(20p/30s) motor and a 20-pole/24-slot(20p/24s) motor are designed and compared. Based on comparison, the 20p/30s design is selected as the final concept. However, the chosen design still has some issues, so detailed analysis and optimizations are made. Since most parameters of motor are interactive, some evaluations and trade-offs are made to accomplish the final design. In the evaluation, the anti-demagnetization, structure strength and temperature distribution are concerned for reliability, the back EMF is concerned for safety of system, cogging torque and torque ripple are concerned for comfort of passenger and impact on transmission, output character and efficiency map are concerned for fuel consumption, and manufacturing, cost and mass are also concerned. And depending on the temperature rise analysis, the continuous power in different revolution speed are calculated. Finally, a prototype is built and tested. The test results show that the design is successful and credible. All performance can meet the requirements.
