Patent ID: 6888272

Claim:
A unipolar transverse flux machine, comprising a rotor ( 12 ) which is rotatable about a rotor axis and having at least one rotor module ( 15 ), each rotor module including two coaxial, toothed, ferromagnetic rotor rings ( 16 , 17 ) and a permanent-magnetic member ( 18 ) for generating a magnetic flux extending radially in opposite directions into the rotor rings ( 16 , 17 ), a stator ( 11 ) which is concentric with the rotor axis and having at least one stator module ( 14 ) associated with the rotor module ( 15 ), the stator module ( 14 ) including an annular coil ( 23 ), disposed coaxially to the rotor axis, and U-shaped stator yokes ( 24 ) fitting over the annular coil, a toothing of the rotor rings ( 16 , 17 ) provided solely on the outer circumference, facing away from the rotor axis, of the rotor rings ( 16 , 17 ), the stator yokes ( 24 ) of the stator module ( 14 ) including yoke legs disposed such that their yoke legs ( 241 ) each face one of the rotor rings ( 16 ) with radial gap spacing, and the permanent-magnetic member ( 18 ) being formed by two permanent magnet rings ( 26 , 27 ) magnetized radially in opposite directions, the permanent-magnetic members ( 18 ) each being surrounded in a manner fixed against relative rotation by one rotor ring ( 16 , 17 ) and being seated on a common flux-conducting element ( 29 ).
