The experimental results demonstrate: the automatic measurement system which bases on the DC dynamometer and DSP can well measure torque-speed characteristic of induction motor.
Employing the control method of DTC, using the squirrel induction motor to construct a full-function AC dynamometer system is a better solution scheme.
运用直接转矩控制方式、使用鼠笼式异步电机构建全功能型交流测功机系统是一种较理想的解决方案。
