The motor drive system almost all use inverter supply power, which output non-sinusoidalvoltage-current and produce non-sinusoidal electromagnetic field.
电机传动系统大都采用变频器供电，输出的是非正弦电压、电流，其在电机中产生非正弦磁场。

The results showed that the sinusoidal output voltage at high Q and non-sinusoidal output voltage at low Q were obtained respectively when the parameters of the load network got various.
结果显示，当放大器的负载网络取不同参数值时，分别得到高q值的正弦输出电压和低q值的非正弦输出电压。

The non-repeatability error and influence induced by temperature and humidity are small when the input voltage is sinusoidal.
