Y-H Series are totally-enclosed, fan-cooled three-phase marine motors of the squirrel-cage type. They are a design variation of the brand-new Y series developed recently and noted for their high efficiency and starting torque. The electric motors are applied for driving various machines on ships such as marine pumps, marine winch, marine capstan, marine cranes, marine generators, marine windlass, marine separators and other marine auxiliaries.
