Abstract
In a unipolar transverse flux machine, to attain a modular structure favorable in terms of production, the stator and the rotor each have the same number of identical stator modules and rotor modules. Each stator module includes an annular coil, disposed coaxially to the rotor shaft, and U-shaped stator yokes fitting over the annular coil. To achieve a high static torque, each rotor module comprises two rotor rings with external toothing, and the rotor rings surround two radially oppositely magnetized permanent magnet rings, which in turn are seated on a common flux-conducting element, which is formed for instance by the rotor shaft produced from ferromagnetic material.
