    摘要: The invention relates to an electrical machine, which comprises at least one permanent magnet and at least one coil (23). The permanent magnet and the coil (23) are configured to move relative to each other and are coupled by a magnetic flux during the relative movement to each other. A magnetic vector field (32) in the permanent magnet and the coil (23) is generated due to the magnetic flux. The permanent magnet is separated by the coil (23) by a main gap (31). Furthermore, the permanent magnet comprises a main gap facing surface portion. The main gap facing surface portion of the permanent magnet is at least partially covered by a layer (15) for concentrating the magnetic vector field in the permanent magnet and the coil (23), thus increasing the magnetic flux between the permanent magnet and the coil (23). Exemplarily, the layer (14) comprises a ferrous material.

    摘要: An IPM motor for a vacuum pump suitable for use as a motor for a small vacuum pump is provided. The IPM motor for a vacuum pump includes: a rotor core in which a rotor shaft of the vacuum pump is pressed and which also has magnets embedded therein; and a stator core which surrounds the rotor core and around which stator windings are wound. The magnets per pole embedded in the rotor core are each split into two pieces and inserted in respective magnet slots in the rotor core. A hole for stress concentration relaxation is provided at either end of each pair of magnet slots in which permanent magnets split into two pieces are embedded in each pole. The rotor core has a multilayer structure having a plurality of rotor core laminations stacked vertically in an axial direction of the rotor shaft. The rotor core laminations stacked vertically are positioned with a skew angle determined by using the holes for stress concentration relaxation.

    摘要: A multilayer laminated rotor is mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement. The rotor has a plurality of laminas, joined together, and voids for receiving magnets. An annular rotor section, which surrounds a shaft opening within which the shaft is receivable, extends between the shaft opening and a radially outer circumferential rotor surface. The annular section mentioned includes an undulating series of the voids in void groups extending from the radially outer circumferential rotor surface inwardly toward the shaft opening and then back toward the radially outer circumferential rotor surface, as well as a solid radially interior portion without any of the voids. Distal voids in the void groups include curved, arcuate, or recurved stress relieving features extending inwardly from radially innermost corner locations of the distal voids.

    摘要: A stator of a rotary electric machine includes a stator core, a coil, and a magnetic body. The stator core is such that a plurality of teeth that protrude out toward a rotor are arranged spaced apart from one another, and a slot is arranged between the teeth. The coil is formed by coil bodies that are stacked, in a direction in which the teeth protrude, in the slot and wound around the teeth. The magnetic body is arranged between the coil bodies that are adjacent in the direction in which the teeth protrude, in the slot. A thickness of the magnetic body in the direction in which the teeth protrude becomes thicker as a distance to the rotor becomes shorter.
