Electro-mechanical transducer e.g. as AC or DC motor/generator

摘要

The electro-mechanical transducer contains devices (20) for generating a magnetic field (H), and at least one system (22) of conducting material, which is arranged in the produced magnetic field, and through which an electric current (I) flows, whereby the system and the devices generating the magnetic field are relatively movable with respect to each other. The system contains parts (26, 24) from at least two different materials with different permeability, which are arranged in such way, that the current through these parts flows in different directions in reference to the magnetic field. The system and the devices generating the magnetic field are interconnected through one or several flexible elements (30) which consist from materials whose permeability is larger than one.
