摘要： An axial flux electrical machine, such as an electric motor, dynamo, pump, generator, or alternator has a casing with vents or openings enabling cooling or pumped media to flow into and out of the casing when the rotor of the electrical machine rotates. The stator is formed from conductive elements connected at their axial outer regions by interconnecting members. Conductive elements have a gap or space to direct cooling through the winding to the central region. A portion of the windings of the stator are spaced apart to allow media to flow between the windings to the central axis area and then is allowed flow outward between the rotor and the stator.

摘要： A magnetically active unit of an electric machine with at least two poles includes a laminated core with slots, and at least one winding for each of the phases. The windings have an electric conductor which forms coil groups in the slots. The coils of the coil groups are formed with at least two sections of the electric conductors of at least one of the windings and are arranged so as to be electrically insulated from each other in the grooves. At least one first coil group of the coil groups of one of the windings has a first number of coils which deviates from a second number of coils of a second coil group of the coil groups of the same winding.

摘要： A stator includes four split cores arranged in the circumferential direction. Each split core includes a yoke including a pair of joint parts, and a tooth. The shape of an end of the tooth is asymmetrical. An angle θ1 (degrees) formed by a side surface of the tooth and a side surface of the yoke on the inner side in the radial direction of the stator satisfies 90 degrees

摘要： A coil wire rod includes a conductor formed of a conductive material, having a uniform outer peripheral shape, and extending in a direction of an axis. The conductor is divided by a division region having a radial shape around the axis in a cross-sectional view orthogonal to the direction of the axis and includes a plurality of stranded wires each extending in the direction of the axis. The division region is twisted about the axis toward the direction of the axis in at least a part in the direction of the axis.
