Research has been carried out along with the plan and the development of estimation method for surface permanent-magnet synchronous motors has been completed. The experimental system was constructed to confirm the validity of the new estimation method and the estimation was implemented. The tested motor is 400 W, and the rotary encoder is mounted on the shaft of the motor to be able to observe the rotation and the position of the rotor. Research results obtained from this study are as follows :1. The rotor position can be accurately estimated by observing the motor current using the optimal voltage vectors.2. The method automatically determining the amplitude and the output time of the optimal voltage vector was developed.3. The generating method of the voltage vector was developed to reduce the estimation time.4. Procedures on the estimation are automated and simplified as much as possible.5. The estimation is implemented within about 12 ms.6. This method can be applied to interior permanent-magnet synchronous motors.7. The average error is ± 1.83 °for the surface permanent-magnet synchronous motor and is ± 1.34 °for the interior permanent-magnet synchronous motor.This estimation method is accurate enough for practically, and the reproducibility of this method is confirmed by the experiment. Sensorless drive for surface permanent-magnet synchronous motors was also discussed as a purpose. However, we could not find the useful step. We have a plan to continue studying this problem.

根据该方案开展了相关研究工作，完成了表面永磁同步电机估计方法的开发。建立了实验系统，验证了新估计方法的有效性，并对其进行了实现。被测电机为400w，旋转编码器安装在电机的轴上，能够观察转子的旋转和位置。本研究得到的研究结果如下：1。利用最优电压矢量观察电机电流，可准确估计转子位置。提出了一种自动确定最优电压矢量幅值和输出时间的方法。为了缩短估计时间，提出了电压矢量的生成方法。评估过程是尽可能自动化和简化的。估计在大约12毫秒内实现。该方法可应用于内置式永磁同步电动机。表面永磁同步电机的平均误差为±1.83°，内部永磁同步电机的平均误差为±1.34°。该估计方法在实际应用中具有足够的精度，并通过实验验证了该方法的可重复性。讨论了表面永磁同步电动机的无传感器驱动。然而，我们找不到有用的步骤。我们计划继续研究这个问题。
