In this paper, the control method for the minimum copper-loss operation of single-phase permanent magnet synchronous motor (SP-PMSM) according to given loads is proposed. The proper inverter output voltage to minimize a copper-loss is calculated from a voltage and current limit. Also, the inverter output voltage can be calculated for all load torque variations under the maximum torque capability curve of the SP-PMSM in all speed range. The proposed control method is simple and easy to implement since it has no inner current controller. The performance of the proposed method is verified by experimental results.

单相永磁同步电机的最大每安培转矩控制，第 2 部分：变速控制方法

本文提出了根据给定负载的单相永磁同步电机(SP-PMSM)最小铜损运行的控制方法。将铜损降至最低的合适逆变器输出电压是根据电压和电流限制计算得出的。此外，逆变器输出电压可以在所有速度范围内 SP-PMSM 的最大扭矩能力曲线下针对所有负载扭矩变化进行计算。所提出的控制方法简单且易于实现，因为它没有内部电流控制器。实验结果验证了所提出方法的性能。
