    • Let the rotating axis whose direction coincides with the direction of the current vector that achieves maximum torque control be called the qm-axis, and the rotating axis perpendicular to the qm-axis be called the dm-axis. A motor control device switches its operation between low-speed sensorless control and high-speed sensorless control according to the rotation speed of the rotor. In low-speed sensorless control, the magnetic salient pole of the motor is exploited, and the d-q axes are estimated by, for example, injection of a highfrequency rotating voltage. In high-speed sensorless control, the dm-qm axes are estimated based on, for example, the induction voltage produced by the rotation of the rotor. During high-speed sensorless control, the γ(dm)-axis current is kept at zero irrespective of the δ(qm)-axis current.
    • 将方向与实现最大转矩控制的电流矢量的方向一致的旋转轴称为qm轴,将与qm轴垂直的旋转轴称为dm轴。 根据转子的旋转速度,电机控制装置在低速无传感器控制和高速无传感器控制之间切换其操作。 在低速无传感器控制中,利用电动机的磁凸极,并且通过例如注入高频旋转电压来估计d-q轴。 在高速无传感器控制中,dm-qm轴是基于例如由转子旋转产生的感应电压来估计的。 在高速无传感器控制期间,无论δ(qm)轴电流如何,γ(dm)轴电流都保持为零。
