Abstract (en)
[origin: WO0249187A2] The invention relates to a unipolar transverse flux machine that comprises, for the purpose of modularity, at least one rotor module (15), two coaxial ferromagnetic rotor rings (16, 17) that are toothed across their outer periphery at a constant circular pitch, and a unipolarly magnetized permanent magnet ring (18) braced between said rings. At least one stator module (14) is concentrical thereto and has a number of yoke-type stator poles (24, 25) that correspond to twice the number of teeth of the rotor module (15). Said stator poles are off-set from one another by a pole division ( tau ) and are disposed with their yoke legs opposite the rotor rings (16, 17), with an air gap in between. The machine is further provided with a toroid coil (23). In order to reduce the ripple content in the torque of the machine, at least one pair of stator pole groups (131 - 134) that have the same number of stator poles is provided. The stator pole groups are off-set from one another by an electrical angle alpha = 180 DEG C/ nu , nu being the ordinal number of the torque ripple suppressed by said off-set.
