HOUSTON -- The 2010 Offshore Technology Conference has awarded a technology Spotlight to Rapp Hydema for its liquid-cooled electric motor. The motor’s cooling fluid circulates though the internal windings and rotating parts to give control of the windings temperature. Internal motor heat is removed by air- or water-cooled heat exchangers connecting externally to the circulating fluid.

The liquid cooling allows more power per motor size and so is space and weight efficient, says Rapp Hydema. The motor is watertight for offshore and marine applications and can be used in single-drive systems for connected to a gearbox.

With 100% continuous torque at standstill or very low speed, Rapp Hydema says the motor is suitable for constant tension systems and active heave compensators.
