Title:
ユニポーラ横磁束電動機
Document Type and Number:
Japanese Patent JP2004516780
Kind Code:
A
Abstract:
In a unipolar transverse flux machine, for its modular construction, at least one rotor module has two coaxial, ferromagnetic rotor rings, toothed with a constant tooth pitch over its outer circumference, and a unipolarly magnetized permanent magnet ring fastened between them, and as at least one stator module, concentric with it, has a number of yokelike stator poles corresponding to twice the number of teeth of the rotor module, the stator poles being offset from one another by a pole pitch (tau) and with their two yoke legs facing the two rotor rings, with an air gap between them, and an annular coil. At least one pair of stator pole groups having the same number of stator poles is formed, and these groups are displaced relative to one another by an electrical angle alpha=180°/nu, where nu is the ordinal number of the harmonic in the torque that is suppressed by this displacement.
