In this paper, a method for analyzing the torque capability of single-phase permanent magnet synchronous motor (SP-PMSM) is proposed. It is an important factor to verify the torque capability of a motor with respect to the motor design and control. This paper proposes the analysis of the motor capability under the inverter output voltage and current constraints using the phasor diagram. Since, the torque capability of the SP-PMSM is determined by both the DC-link voltage and rated current of the motor and the inverter, the torque capability curve of the SP-PMSM is analyzed through these limitations and the motor parameters. The magnitude and the phase of the inverter output voltage for the maximum torque per ampere are explicitly calculated. Several simulation and experimental results are presented to verify the proposed theoretical analysis.

单相永磁同步电机的最大每安培转矩控制，第 1 部分：最大转矩能力分析

在本文中，提出了一种分析单相永磁同步电机（SP-PMSM）转矩能力的方法。在电机设计和控制方面，验证电机的扭矩能力是一个重要因素。本文提出了使用相量图分析逆变器输出电压和电流约束下的电机能力。由于 SP-PMSM 的转矩能力由电机和逆变器的直流母线电压和额定电流共同决定，因此通过这些限制和电机参数来分析 SP-PMSM 的转矩能力曲线。明确计算出每安培最大转矩的逆变器输出电压的幅值和相位。提出了几个模拟和实验结果来验证所提出的理论分析。
