Abstract:
A unipolar transverse flux machine, comprising a housing; a rotor rotatable about a rotor axis, said rotor having at least one rotor module assembled from two coaxial ferromagnetic rotor rings toothed with a constant tooth pitch and one permanent-magnet ring fastened between said rotor rings and magnetized unipolarly in a direction of said rotor axis; a stator which is concentric with said rotor axis and having at least one stator module associated with said rotor module and including an annular coil disposed coaxially to said rotor axis and U-shaped stator yokes fitting over said annular coil and fixed with a pitch corresponding to a tooth pitch of said housing, said rotor rings having a toothing provided solely on an outer circumference of said rotor rings remote from said rotor axis, said stator yokes in said stator module being disposed such that one leg of each of said stator yokes is located facing one of said rotor rings and another leg of each of said stator yokes is located facing another of said rotor rings the stator legs are facing the respective rotor rings with a radial gap spacing; and one short-circuit element each disposed between successive ones of said stator yokes in a direction of rotation of said rotor and extending axially over both said rotor rings and facing said rotor rings with a radial gap spacing.
