Verified by model calculation and calculated the present example electromagnetic field equation of motor on non-linear sine alternation eddy.
并实例计算了非线性正弦交变涡流的电机电磁场方程。
The Sine wave Pulse Width Modulation (SPWM) is used to reduce the wastage and the noise of the motor more effectively, as comparing to the equal pulse width modulated PWM.
相对于等宽脉宽调制PWM，正弦波脉宽调制SPWM可以有效地降低电动机的损耗和噪声。
The performance test was carried out for AMD control system driven by linear motor under the sine directive force with different frequencies and amplitudes.
然后对直线电机驱动的AMD控制系统进行不同频率和幅值的正弦力指令试验。
