Electrical steel sheet for traction motor of hybrid/electrical vehicles

Wakisaka, Takeaki / Arai, Satoshi / Kurosaki, Yousuke

15 years have passed since the first commercial hybrid electric vehicle (HEV) was sold. Meanwhile, the market has been expanding and the type of HEV/EV has been increasing, and then demands to electrical steel sheet for traction motor cores of HEV/EV has become diversified. In this paper, the demands to electrical steel sheet for traction motor cores of HEV/EV are reconfirmed, and then newly developed electrical steel sheet and the application techniques of electrical steel sheet are informed. With the expanding market for HEV/EV and the increase in the number of HEV/EV models, traction motors for HEV/EV are becoming smaller in size, lighter in weight, and higher in efficiency. At the same time, new electrical steel sheets for the motor cores have been developed to meet the new requirements. The material factors that affect the magnetic properties of an electrical steel sheet differ according to the conditions under which it is used. Therefore, it is necessary to choose a suitable electrical steel sheet and pay due attention to the operation conditions of the traction motor. In addition, since the motor performance characteristics are influenced by the motor's operating conditions, it is important to evaluate the motor performance by numerical analysis taking into consideration the core construction, processing/fixing methods, motor control system, etc.
