摘要
提出了一种测量封闭体内电动机转速的方法。通过测量异步电动机定子电流内的转子槽谐波频率分量和偏心频率分量,辨识出转子槽数,用转子槽谐波频率和转子槽数获得电动机的转速。
This paper proposes a speed measurement scheme of asynchronous motor in closed body, by measuring rotor slot harmonic and eccentricity harmonics in stator current, identify the number of rotor slot, using slot and eccentricity harmonics to get the speed of asynchronous motor with rotor slot harmonic and the rotor slot number.
