VARIABLE FREQUENCY DRIVE - gsengr.com

VFDRECOMMEN-DATIONSVARIABLE FREQUENCY DRIVEThe synchronous speed of an induction motor isprimarily a function of the number of poles andthe FREQUENCY :A slip between actual and synchronous speed isgenerated by the applied load torque. This slip isusually small, typically 1-3% of synchronous way to achieve a VARIABLE speed motor is to varythe FREQUENCY . Such a device is called a frequencyconverter. FREQUENCY converters, also called vari-able speed drives, are usually installed to allow fora better process control and to save energy. Theusage of VARIABLE FREQUENCY DRIVE (VFD) control inpump applications is becoming increasingly com-mon.
