Applying VFDs to existing motors | Processing Magazine
Motor frequency The output frequencies of VFDs can match any motorrated frequency. Since the VFD controls the motor speed and frequency, this can allow a motor rated for one power system, 60 hertz (Hz), for example, to be operated effectively and at full rating on a 50-Hz power system. Motor speed Motor bearings may depend on speed for lubrication.
