A motor with a flat wire is provided. Since spatial collisions which occur in horizontal and vertical directions can be prevented by flat wire patterns which intersect with each other and are stacked on slots of a stator core, there is an advantageous effect in that a motor is miniaturized.

In one possible implementation, a motor is provided including a rotor and a stator. Front cooling fins are thermally coupled to a front of the stator, and rear cooling fins are thermally coupled to a rear portion of the stator. The winding is between the front and rear cooling fins.

An electric machine including a stator having a fully non-magnetic core and stator windings formed of a non-superconducting transposed conductor to reduce eddy current losses. It further includes a rotor having a fully non-magnetic core and superconducting windings or superconducting magnets which produce a magnetic field for interaction with the stator windings. A cryogenic cooling system is arranged to cool the stator windings to reduce conduction losses in the stator windings.

One aspect of a stator of the present invention is a stator disposed radially outside a rotor rotatable about a center axis line. The stator includes a winding portion including a plurality of conductors, a stator core in which a plurality of slots through which the conductor passes are provided, and a plurality of bus bars disposed on one side in an axial direction of the stator core. The plurality of conductors include a terminal conductor including two straight portions passing through two different slots and a bent portion connecting ends of the two straight portions on one side in the axial direction of the stator core. The terminal conductor is connected to the bus bar at the bent portion.

A rotating electric machine includes a rotor rotatably supported and also including a magnet portion; a stator including a stator winding; and a plunger configured to displace the rotor and the stator relative to one another along an axial direction of the rotating electric machine. The stator includes a slotless structure in which at least one of no magnetic teeth and slot is provided. Thus, an attracting force acting between the magnet portion and the stator is weakened, thereby the rotor and the stator are easily displaceable relative to each other by the plunger.

Stators are already known which in each case comprise an annular stator stack having grooves which are open towards an axis of the stator and in which an electrical winding is provided which comprises a plurality of winding branches. The plurality of winding branches each have a plurality of parallel wires for reducing the so-called skin effect. The parallel wires are arranged in the grooves, wherein the winding branches in their configuration each form a plurality of turns of a coil which are each part of an electrical coil, wherein a turn of a coil is formed in each case by two sides of a turn, lying in different grooves, of one of the winding branches and by a turn side connector which connects the two sides of a turn to one another. In electrical windings having parallel wires, an unfavourable wire position and a resulting linking of different magnetic flows may lead to disadvantageous compensating or circular currents which produce additional copper losses in the electric motor. In the stator according to the invention the compensating or circular currents in the parallel wires are avoided or at least decreased. According to the invention, the parallel wires (Z) which are arranged in the same groove (2) are in each case provided in a common groove section (y.sub.f) of the respective channel (2) having a groove section height (H.sub.f), wherein the groove section (y.sub.f) in each case comprises, arranged one above the other in the radial direction, layered regions (y1 . . . yn), wherein in each case the parallel wires ( ) which belong to the same side of a turn arc arranged in the same layered region (y1 . . . yn) of the groove section (y.sub.f).
