WhisperPower launches Hybrid Propulsion System

WhisperPower’s complete range of hybrid propulsion systems, from 5-250kW, is based on a high efficiency permanent DC magnet motor.  The system powers the propeller, and a variable rpm generator with one, three, five or six cylinders, which engenders electric power and charges the Li-ion batteries. Shore power or a shaft generator, when sails are in use, can also charge the batteries.

The batteries power the propulsion, hydraulics and/or other power consumers, with or without the use of an inverter.

Integrated management technology fires up the generator automatically, raising the rpm when power demand increases. When power demand falls it slows the rpm or shuts off the generator.

WhisperPower’s hybrid propulsion system will be installed on two J-class yachts, which are under construction at Holland Jachtbouw, in mid-2011: 39.5m Rainbow, and the recently ordered 40m Yankee.
