Inquiry Form

The YVF2-H Series of variable frequency adjustable speed three-phase induction motor is efficient and energy-saving. Equipped with a frequency converter, this adjustable speed motor has low noise and vibration, a high starting torque, small starting current, reliable operation, and convenient maintenance. Flat and step less speed regulation can be done in 3(5)~100Hz or more. Equipped with an independent forced cooling fan, the induction motor is ideal for machinery on land or water.

The motors comply with IEC60034-1 rating and performance for rotating electrical machines and with the standards for the following specifications:
IEC60034   Rotating electrical machines
IEC60068   Environmental testing
IEC60072   Dimensions and power ratings for rotating electrical machines
