Variable Frequency Adjustable Speed Induction Motor

The YVF2-H series of variable frequency adjustable speed three-phase induction motor is an energy-efficient AC adjustable speed motor. Equipped with a frequency converter, the induction motor features low noise and vibration, a high starting torque, small starting current, and reliable operation. Flat and step less speed regulation can be done in 3(5)~100Hz or more and an independent forced cooling fan makes the motor long lasting. The motor drives various machines on ships such as pumps, blowers, separators, hydraulic engines and other auxiliary equipment.
This series is designed according to IEC60034-1《Rotating Electrical Machines—Rating And Performance》and "Rules for the Construction of Sea-Going Steel Ships." Motors also comply with the following specifications.

IEC60034 Rotating electrical machines
IEC60068 Environmental testing
IEC60072 Dimensions and power ratings for rotating electrical machines
IEC60092 Marine electric accessories

The motors also meet international standards for the following Ship Classification Societies:
LR Lloyd’s Register of Shipping
GL Germanischer Lloyd
NK Nippon Kaiji Kyokai
BV Bureau Veritas
KR Korea Register of shipping
RINA Registro Italiano Navale
ABS American Bureau of Shipping
