Due to the abrupt changes in voltage in the VSI output, the motor line current tends to be discontinuous and rich in harmonics. A sketch of the typical motor current for a VSI is shown in Figure 4. At low frequency, the current harmonics create cogging. Cogging means the rotation of the motor shaft is not smooth.احصل على السعر
