Variable Frequency Drive

Send Inquiry

We are manufacturing Variable Frequency Drives that are an inexpensive solution to the conventional DC motor. These are used for controlling the speed of an AC / synchronous motor. These drives are very important for speed control with complete torque, which is possible via the maximum rated speed. If the latter speed needs to be surpassed, then torque needs to be reduced. The variable frequency drives or VFDs operate by manipulating the output frequency via alteration of incoming AC current to DC.
