在本文中，永磁（PM）游标电机的反电动势和功率方程精确推导考虑气隙磁导函数表示的实际机器尺寸。使用这些方程，PM游标电动机的性质进行了分析调查，并提供了大量的信息，如主要的几何因素影响转矩和最大可获得的转矩为给定的电流，导致每气隙体积的转矩一个新的关系。此外，这些方程提供了一种确定槽和极组合的方法，以实现更大的功率密度。最后，增加电抗的影响进行了研究，在给定的电压与机器性能。
In this paper, the back electromotive force and power equations of a permanent-magnet (PM) vernier motor are accurately derived considering an air-gap permeance function expressed in terms of practical machine dimensions. Using these equations, the nature of a PM vernier motor is analytically surveyed, and substantial information such as main geometric factors affecting torque and the maximally obtainable torque for a given current are provided, leading to a new relation for torque per air-gap volume. In addition, these equations provide a means to determine the slot and pole combinations to realize greater power density. Finally, the effects of an increased reactance are investigated in respect to machine performance with a given voltage.
