摘要： An electric motor includes a stator and a rotor. One of the stator and the rotor includes a magnetic core, preferably an iron core. A reactive metal or a mixture or reactive metals is fixed to the magnetic core. The or each reactive metal has a reactivity greater than the reactivity of the metal of the magnetic core. A rotor and a stator is also provided. By fixing the reactive metal or metal mixture to the magnetic core of the motor, rotor or stator, oxidation and corrosion of the core can be avoided or reduced.

摘要： A method of manufacturing dynamoelectric machines includes producing a first plurality and a second plurality of stator and rotor laminations using a die press, forming a first rotor from the first plurality of rotor laminations, and forming a second rotor from the second plurality of rotor laminations. The first plurality and the second plurality of stator laminations have the same inner and outer diameters. The first plurality and the second plurality of rotor laminations have the same inner and outer diameters. The first plurality of rotor laminations have a first magnet slot configuration and the second plurality of rotor laminations have a second magnet slot configuration different than the first magnet slot configuration. The first rotor and the second rotor may have the same or different stack heights. Preferably, a ratio of each stator lamination's inner diameter to outer diameter is at least 60%.

摘要： For miniature drives which are used in particular in car locks, the axial play of the motor spindle is prevented, or is at least greatly restricted, by the necessary axial stop and also the further motor stop being assigned to the housing cover of the housing. When the housing cover is placed onto the housing casing, said axial stops are inserted into corresponding guides in such a manner that said axial stops subsequently not only restrict the play of the motor spindle and ensure an always uniformly secure arrangement of the motor housing in the housing, but at the same time also make possible the substantially simpler production of the required bearing bore. Said bearing bore and the associated aperture are produced from the outer side of the housing casing during the injection molding.

摘要： An electric machine includes a rotor assembly having a rotor core that extends in an axial direction and a stator assembly surrounding and coaxial with the rotor assembly. The stator assembly includes a stator core having slots extending in a radial direction into an inner surface of the stator core and extending axially from a first end surface to a second end surface of the stator core. The stator assembly includes stator coil windings disposed within the respective slots of the stator core and a first electrically insulating conformal coating disposed between the stator core and the stator coil windings. The conformal coating includes a polymer matrix impregnated with an effective amount of thermally conductive ceramic materials, above a percolation threshold, that form continuous thermal pathways across a thickness of the first coating.

摘要： A stator unit for use in a motor includes a cylindrical bearing housing, a stator core, a resin insulator, a conductive wire, a circuit board, a molded resin portion, and an elastic member. The stator core is fixed to an outer circumferential surface of the bearing housing. The insulator is attached to the stator core. At least one of the bearing housing and the insulator has a ring-shaped groove. The conductive wire is wound around the teeth with the insulator therebetween. The circuit board is electrically coupled to the conductive wire. The molded resin portion covers the stator core, the insulator, the conductive wire, and the circuit board. The elastic member is fitted in the groove and interposed between the bearing housing and the insulator.
