Abstract: A transverse flux machine (TFM) includes a stator assembly that provides a plurality of U-shaped magnetic circuits placed circumferentially around a rotor assembly. The plurality of U-shaped magnetic circuits being comprised of a first stator segment, a second stator segment, and a plurality of stator yokes. The first stator segment and the second stator segment each have a plurality of poles spaced around a first circumference and a plurality of slots spaced around a second circumference opposite each of the plurality of poles. The plurality of stator yokes each have a first end sized to fit within one of the slots associated with the first stator segment and a second end sized to fit in one of the slots associated with the second stator segment.

Abstract: A stator of an electrical machine has a cross section, a longitudinal extension, a jacket surface, a plurality of winding holders configured for receiving field windings, the winding holders being distributed inhomogenously around an inner circumference of the cross section, such that a density of the field windings in at least one first region formed around a stator circumference is smaller than in an adjacent second region.

Abstract: A rotor is accommodated in a yoke housing. Six magnets are arranged at equal intervals in the circumferential direction on the inner circumferential surface of the yoke housing so as to face the rotor. The core is generally cylindrical and includes an annular portion at an anti-output side and a balance at an output side. The magnets have six poles so as to effectively narrow a basal path width of the core in which the line of magnetic force concentrates most and magnetic saturation is likely to occur most. This reduces the diameter of the core. Therefore, the motor is effectively miniaturized in the axial direction and in the radial direction without complicating the formation steps.
