用于电动汽车（EV）的永磁同步电机（PMSM）需要三个特性；高转矩，低转矩区域效率高，宽转速范围内输出稳定。然而，它们在磁场磁通的大小上有一种权衡关系。本文介绍了一种具有结构变磁场磁通的铁氧体永磁电机和磁场绕组的顺极永磁式轴向间隙电机。此外，为了检查所提出的电机的运行特性，制作了一个原型并进行了测试。实验结果表明，该结构能够有效地实现上述三种特性；高转矩，低转矩区域效率高，宽转速范围内输出稳定。
Permanent magnet synchronous motors (PMSM) for electric vehicles (EV) requires three properties; high torque, high efficiency at low torque region, and constant output in wide speed range. However, these have a relation of a trade-off at magnitude of field magnetic flux. In this paper, consequent pole PM type axial-gap motor with the ferrite PMs and the field windings, which has structure variable field magnetic flux, is introduced. Also, in order to examine operation characteristics of the proposed motor, a prototype is produced and tested. Experimental results show that the proposed structure is effective in realizing all of three properties; high torque, high efficiency at low torque region, and constant output in wide speed range.
