摘要
利用电功率测量法实现对变频电源控制下异步电机转矩的测量,同时系统还能测量出异步电机工作时的有功功率、转速、三相电压、电流等参数。该系统性价比较高,性能稳定且移植性好。
The torque measurement of asynchronous motor controlled by frequency conversion power was realized while the asynchronous motor was working by making use of the electric power measurement. At the same time, the active power, rotational speed, three-phase voltage, alternating current and other parameters could be measured using the system which showed high performance price ratio, stable and transplanted properties.
