The M2E-H series of high efficiency three-phase induction motors are completely enclosed fan-cooled marine motors of the squirrel-cage type. This series features low noise, high insulation, and multiple safety systems. These efficient induction motors drive various machines on ships such as pumps, blowers, separators, hydraulic engines and other auxiliary equipment.The motors comply with National Standard IEC60034-1 for the rating and performance of rotating electrical machines and for GB18613-2012 for energy-efficient sea-going vessels. This motor is also approved by CCS and meet the following standards:
IEC60034            Rotating electrical machines
IEC60068            Basic environmental testing procedures
IEC60072            Dimensions and power ratings for rotating electrical machines
IEC60092            Electrical installation in ships

The motors also meet international specifications for the following Ships Classification Societies.
