Electrical machine for motor vehicle for production of electricity from flow energy contained in exhaust gas stream, has wing mounted in pivotably-movable manner such that angle of wing is adjusted

摘要

The machine (1) has a transducer (10) for conversion of periodic tilting movement of a wing (3) into electrical energy. The wing is arranged in an exhaust gas stream (2). The wing is mounted in a pivotably-movable manner such that angle of the wing is adjusted. Spring elements (4, 5) are provided for mounting the wing. One of the spring elements is provided in front at the wing in a flow direction, and the other spring element is provided at back in the flow direction. The wing is designed as an even plate, and the transducer is designed as a moving coil or piezo ceramic transducer.
