YVF2

YVF2 variable-frequency three-phase asynchronous motors

YVF2 motors are designed for inverter duty in frame sizes 80–355. A sturdy cast-iron or aluminium-alloy housing gives a wide, precise speed range, and mounting dimensions and power ratings match the YE2 series for easy interchange. A separately driven cooling fan keeps the motor cool at any speed.
