Patent ID: 6882066

Claim:
A unipolar transversal flux machine, in particular a unipolar transversal flux motor, comprising a rotor ( 12 ), which is non-rotatably supported on a rotor shaft ( 13 ) and is comprised of two coaxial ferromagnetic rotor rings ( 14 , 15 ), which on their outer circumference remote from the rotor shaft ( 13 ), are provided with constant tooth spacing, and having a permanent magnet ring ( 16 ), which is magnetized in an axially unipolar fashion and is clamped axially between the rotor rings ( 14 , 15 ), and a stator ( 11 ), which is concentric to the rotor shaft ( 13 ) and has U-shaped stator yokes ( 19 ) with two yoke legs ( 191 , 192 ) that are connected to each other by a crosspiece ( 193 ), which stator yokes ( 19 ) are fixed to a housing ( 10 ) with a spacing that corresponds to the tooth spacing, and are disposed so that the one yoke leg ( 191 ) is disposed opposite the one rotor ring ( 14 ) and the other yoke leg ( 192 ) is disposed opposite the other rotor ring ( 15 ), each with a radial gap distance, yoke elements ( 20 ), each of which is disposed between respective stator yokes ( 19 ) arranged one after the other in the rotation direction of the rotor ( 12 ), extends axially over the two rotor rings ( 14 , 15 ), and is disposed opposite them with a radial gap distance, and a stator winding ( 21 ), the stator winding ( 21 ) having two coils ( 22 , 23 ), each with two coil sides ( 221 , 222 or 231 , 232 ), whose one coil side ( 221 or 231 ) extends coaxial to the rotor shaft ( 13 ), respectively over a group of stator yokes ( 19 ) and yoke elements ( 20 ) arranged in succession in the circumference direction, along the side of the yoke elements ( 20 ) remote from the rotor shaft ( 13 ), between the yoke legs ( 191 , 192 ), and wherein the group spanned by the coil side ( 221 ) of the one coil ( 22 ) is disposed spatially offset on the stator circumference and electrically offset by 90° in relation to the group spanned by the coil side ( 231 ) of the other coil ( 23 ).
