Abstract: The miniaturization of electrodynamic converters causes and over-proportional reduction in power conversion density. The particular functional arrangement of the elements inside the power converter makes it possible to involve nearly the entire volume in the power conversion process. Flux concentration and multiple functions of different components permit and increase in the power conversion density in comparison to conventional miniaturizable converters. By rotating the toothed element wheel (9), an alternating magnetic flux from the permanent magnet elements (14) of the alternating axially polarized magnet ring (13) is conducted through the holed pin (1) via different magnet flux elements (21). Axially/radially oriented magnetic circuits (19) surround a flat coil (11) resting on the holed pin (1) and exert an induction action there.
