A Variable Speed Drive (VSD) is a device that can control the speed of an electric motor. Most conventional motors run at full speed only, but a VSD-equipped unit means it can run at a variable rate. This allows the motor to drive a pump or fan at a speed appropriate to the requirements of the process.
