Claims
- 1. 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 other at least some portions of the connected legs (7.2, 7.3) of several strands are used jointly for conducting the flux; and a thickness of the connected, jointly used legs (7.2, 7.3) is reduced in accordance with predetermined flux conditions.
- 2. A transverse flux machine according to claim 1,wherein a pole height (du) in a region where the legs of respective U-shaped yokes (7.1 to 7.4) are not bent toward one another is higher than a pole height (dl) of the I-shaped yokes (3), at least in the region of the winding (1. 1 to 1.3).
- 3. A transverse flux machine according to claim 1,wherein the U-shaped yokes (7.1 to 7.4) and the I-shaped yokes (3) are laminated in an axial direction.
- 4. A transverse flux machine according to claim 3, characterized in thatwherein that yokes are designed such that they can be divided.
- 5. A transverse flux machine according to 1,wherein the U-shaped yokes (7.1 to 7.4) and I-shaped yokes (3) are designed as strip-wound cut cores.
- 6. An embodiment of the transverse flux machine according to claim 1, with an inside or outside rotor, or in the form of a linear motor.
- 7. A transverse flux machine according to claim l,wherein a means for conducting cooling agent, which is arranged in a winding window of the U-shaped yokes (7.1 to 7.4), runs essentially parallel to the annular winding (1. 1 to 1.3) and is thermally closely connected to the yokes (7.1 to 7.4) and the annular winding (1. 1 to 1.3).
- 8. A transverse flux machine according to claim 1,wherein an insulating support structure is provided, at least in a region of high leakage flow between the U-shaped yokes (7.1 to 7.4) and the I-shaped yokes (3).
