An Integrated Wankel Expander-Alternator
Abstract
A compact Wankel expander-alternator combination is provided. The combination includes a stationary outer housing that has embedded stator coils and a rotating inner housing having corresponding magnets disposed around the housing with the magnet/coil interaction generating power. Within the rotating housing, a three-sided rotor turns within a two lobed Wankel cavity, powered by working fluid acting on the rotor. The rotating housing and the rotor each circumscribe a stationary shaft. The shaft has an eccentric lobe about which the rotor turns on a bearing disposed between the rotor and the lobe. The rotating housing turns on bearings supported by the stationary shaft. The rotor and rotating housing are linked so that as the rotor turns in response to the working fluid force, the housing turns at a higher speed the speed ratio being preselected to achieve the desired output energy.
