分析了表面贴装式永磁电机的高频脉动电压信号注入法无位置传感器控制算法。在估计的转子参考系的SMPM机的简化的高频模型的开发。然后，在高频下的SMPM机的阻抗进行了分析，通过有限元分析（FEA），并与阻抗测量使用脉冲宽度调制（PWM）逆变器系统在各种注入条件下进行比较。有限元分析和高频阻抗测量的结果是相互一致的，并给出了物理见解SMPM机器的无传感器操作。在分析SMPM电机无位置传感器控制算法的基础上，给出了利用商用SMPM电机进行速度控制和位置控制的实验结果。
This paper presents the analysis of the surface mounted permanent magnet (SMPM) machine for the sensorless control algorithm using the high frequency fluctuating voltage signal injection method. A simplified high frequency model of a SMPM machine in the estimated rotor reference frame is developed. Then, the impedances of a SMPM machine at high frequency are analyzed by finite element analysis (FEA) and is compared with impedance measurements using a pulse width modulation (PWM) inverter system under various injection conditions. The results of the FEA and high frequency impedance measurements are coincident with each other, and give physical insights in sensorless operation of the SMPM machine. The experimental results of speed control and position control using a commercial SMPM machine are presented based on the analysis of the SMPM machine for the sensorless control algorithm.
