Patent ID: 8847458

Claim:
An electrical machine, comprising: an armature, a field magnet arrangement, wherein the armature and the field magnet arrangement are separated by a gap from each other, wherein the armature and/or the field magnet arrangement comprises a plurality of coils, wherein each coil comprises conductive body sections, wherein the body sections of the coils are joined electrically by conductive end sections, wherein each end section is symmetrical with respect to a plane passing axially through the winding end section, wherein at a first end of the armature a first end section of a first coil of the armature is tilted in a first direction away from the armature by a first angle in respect to the body section of the first coil of the armature, at the first end of the armature a first end section of a second coil of the armature is tilted in a first direction away from the armature by a second angle in respect to the body section of the second coil, at the first end of the armature a first end section of a third coil of the armature is tilted in a first direction away from the armature by a third angle in respect to the body section of the third coil, each of the first, second, and third angles different from other ones of the first, second, and third angles, wherein the first direction away from the armature is toward or away from the field magnet arrangement, and at a first end of the field magnet arrangement a first end section of a first coil of the field magnet arrangement is tilted in a direction away from the field magnet arrangement towards the armature by a fourth angle in respect to the body section of the first coil of the field magnet arrangement, at the first end of the field magnet arrangement a first end section of a second coil of the field magnet arrangement is tilted in a direction away from the field magnet arrangement towards the armature by a fifth angle in respect to the body section of the second coil of the field magnet arrangement, at a first end of the field magnet arrangement a first end section of a third coil of the field magnet arrangement is tilted in a direction away from the field magnet arrangement towards the armature by a sixth angle in respect to the body section of the third coil of the field magnet arrangement, the fourth, fifth and sixth angles different from other ones of the fourth, fifth and sixth angles.
