摘要

本文介绍了利用空间谐波功率代替永磁体进行磁场磁化的自激绕线场同步电动机的数学模型对转子绕组电流的估计。用同步旋转参照系上的电压方程说明了该电机的工作原理。在此基础上，对转子绕组电流进行了有限元仿真与数学计算的比较。结果表明，两者在稳态下的运行特性非常吻合，并表现出相似的趋势。

Estimation of rotor current based on mathematical model of wound-field synchronous motor self-excited by space harmonics

This paper describes estimation of the rotor winding current based on a mathematical model of a self-excited wound-field synchronous motor where the space harmonics power is utilized for the field magnetization instead of the permanent magnets. The operation principle of the proposed motor is explicated by a voltage equation on the synchronous rotating reference frame. Furthermore, the rotor winding current is compared between the FEM based simulation and the mathematical calculation. Consequently, it has been confirmed that both operation characteristics in the steady state agree very well and indicate similar tendency.
