Abstract:
A multi-strand transverse flux machine with unilateral stator and rotor, wherein:essentially U-shaped yokes that are assigned to the strands and essentially I-shaped yokes are respectively alternately arranged one behind the other in one plane in the stator with electrical annular windings;a rotor is provided with permanent magnets that are attached planar to its surface adjacent to the yokes, said rotor having a circular back iron;the permanent magnets are arranged in rows, mechanically displaced against each other;currents flowing through the annular windings are electrically displaced accordingly;legs (7.1 to 7.4) of the U-shaped yokes of each individual strand are bent toward each other in each plane;adjacent legs (7.2, 7.3) of the strands, which are respectively arranged in one plane, are connected to each otherat least some portions of the connected legs (7.2, 7.3) of several strands are used jointly for conducting the flux; anda thickness of the connected, jointly used legs (7.2, 7.3) is reduced in accordance with predetermined flux conditions.
