直流伺服电机的磁阻力矩难于直接测量,但在伺服电机和测速机的组合系统中,可借助X—Y记录仪对伺服电机的电流和转速(通过测速机)进行测量,并进行简单的计算即可。进一步的分析表明:磁阻力矩只影响以伺服电机为执行元件的伺服系统的低速平稳性,高速时因电机的固有特性而使其衰减。
The reluctance torque of a DC servo motor is difficult to measure directly. However, in the combination of servo motor and tachometer, the current and speed of the servo motor (through the tachometer) can be measured by the X-Y recorder and simply calculated Can be. Further analysis shows that the reluctance moment only affects the low speed stability of the servo system with servo motor as the actuator, which is attenuated due to the inherent characteristics of the motor at high speed.
