提出了一种新型的顺极永磁电动机，该电机的N、S极对均具有镜像极对。由于转子配置，电动机的三相同步阻抗是平衡的。此外，可以用较小的d轴电流进行磁场削弱，这导致在高速范围内的高效操作。然而，由于PM体积较小，电动机仍然具有在低速下产生低扭矩的缺点。为了解决这一问题，本文讨论了一种转矩提升操作，通过引入零相绕组的电机和三相四线制电机驱动电路与逆变器。本文介绍了一种新提出的顺序极永磁电机的基本原理及其运行特性，并研究了使用该系统的转矩提升方法。
A novel consequent-pole permanent magnet (PM) motor is proposed in the paper, which has image pole pairs for every pole pair of N and S. The three-phase synchronous impedances of the motor are balanced owing to the rotor configuration. In addition, it is possible to carry out field weakening with less d-axis current, which leads to a highly efficient operation in a high-speed range. However the motor still has a drawback of low torque generation at low speeds due to less PM volume. In order to solve the problem, the paper discusses a torque boost operation by introducing a zero-phase winding to the motor and a three-phase four-wire motor drive circuit with an inverter. This paper describes a basic principle of the newly proposed consequent-pole PM motor and its operation characteristics, and investigates the torque boost approach using the proposed system.
