YVF2 Series Variable Frequency Adjustable Speed Three Phase Induction Motor is AC high-efficiency and energy-saving adjustable speed motor. Equipped with the frequency converter, it is a new product for speed regulation of electromechanical integration. It offer such features as low noise and vibration, high starting torque, small starting current, simple construction, reliable working, convenient maintenance and wide usage scope etc. Flat and step less speed regulation can be done in 3(5)~100Hz or more. It is equipped with an independent forced cooling fan. Best cooling effort has been got at any speed. It is suitable for driving various machines on ships such as pumps, blowers, separators, hydraulic engines and other auxiliary equipment.

YVF2 series are designed according to IEC60034-1《Rotating electrical machines—Rating and Performance》.
The motors are also complied with the relevant requirements of the following standards and specifications.
IEC60034 Rotating electrical machines
IEC60068 Environmental testing
IEC60072 Dimensions and output ratings for rotating electrical machines
