Frequency Inverter Brings Revolution to Industrial Washing EquipmentIn the past, washing equipment was driven by an on-off switch or constant voltage. The use of a frequency inverter has brought revolutionary development in drive technology, and now it is one of the most useful electrical devices u

1. What is VF controlFor asynchronous motors, in order to ensure that the motor flux and output force remain unchanged (constant torque). When the motor changes frequency, the ratio of voltage V and frequency F needs to be maintained approximately unchanged. This method is what we called constant vo
