摘要： An axial-gap-dynamoelectric machine includes resin bobbins having positioning protrusions, and a stator core including a base yoke having a plurality of tooth holes and positioning holes. In each tooth hole, a circumferential length of a tooth-hole-radial-direction-outer-end surface is larger than a circumferential length of a tooth-hole-radial-direction-inner-end surface. Each of the plurality of teeth has a columnar shape in which a circumferential length of a tooth-upper surface is larger than a circumferential length of a tooth-bottom surface. The positioning protrusions are inserted in the positioning holes, and press the teeth against the base yoke inward in the radial direction such that the tooth-bottom surface is brought into contact with the tooth-hole-radial-direction-inner-end surface and the tooth-oblique surface is brought into contact with the tooth-hole-circumferential-direction-end surface.

摘要： A rotary electrical device includes a rotor configured to be rotatable; and a stator disposed in a radial direction of the rotor to surround a rotation axis of the rotor. The stator includes a plurality of stator units that are stacked in an axial direction of the rotor. Each of the stator units includes a winding, a stator core that surrounds the winding, and one or more claw magnetic poles that protrude radially toward the rotor from each of two end portions in an axial direction of the stator core. The rotor includes a magnet that radially faces at least a portion of any of claw magnetic poles of the stator at a predetermined rotation position. At least one of magnet end portions in an axial direction of the magnet protrudes further in the axial direction than all of the claw magnetic poles of the stator.

摘要： A cylindrically-shaped motor shaft forming a rotational axis of a motor includes a processing target region, a spiral groove, and a reverse spiral groove intersecting with the spiral groove at at least one point. The processing target region has a first end closer to a bottom face of the cylindrical shape and second end closer to a top face side of the cylindrical shape. At least one turn of the spiral groove surrounds an outer circumferential surface in the processing target region. The reverse spiral groove surrounds the outer circumferential surface in the processing target region in a direction reverse to that of the spiral groove.

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 hybrid stator core for an axial flux electric machine is described herein. The hybrid stator core includes a laminated component and at least one soft magnetic composite (SMC) component. The laminated component includes a first block section, a first tab, and a second tab, the first block section having a first end, a second end opposite the first end, a first side surface extending between the first and second ends, and a second side surface opposite the first side surface. The first tab projects from the first side surface adjacent to the first end of the first block section. The second tab projects from the first side surface adjacent to the second end of the first block section. The at least SMC component is configured to abut the first side surface of the first block section. The first and second tabs are configured to hold the at least one SMC component therebetween.

摘要： A metallurgical device, in particular a casting installation, rolling mill or strip processing installation, including at least one machine part rotating about an axis, wherein an energy consumer that is in electrical connection with an energy source is arranged in the machine part. To supply the energy consumer with energy on a sustained basis in spite of adverse ambient conditions, the energy source is designed as a generator which is in connection with the rotating machine part for rotation therewith, wherein the generator is otherwise free of any mechanical connection with the metallurgical device and wherein the generator has a housing element, on which at least one eccentric mass arranged at a location that is at a distance radially from the axis.
