    Abstract: In a rotor having plural permanent magnets secured on a rotary shaft for use in, e.g., an electric motor which is incorporated preferably into a rack-type electric power steering device, a cylindrical cover is fit on the rotary shaft to cover the external surfaces of the plural permanent magnets, and one or both axial end portions of the cylindrical cover are plastically deformed thereby to secure the cylindrical cover onto the rotary shaft. Thus, the cylindrical cover is firmly secured to the rotary shaft and, even when one or more permanent magnets are separated from the rotary shaft or broken, prevents the separated permanent magnets or the broken fragments from scattering within a housing of the motor.

    Abstract: The rotor has a core with an internal space. Permanent magnets are arranged on the core. These permanent magnets are surrounded by an outer cylinder, which is connected flush to closure disks which bear stub shafts. Channels run out from the internal space in the radial direction to the region of the permanent magnets. A resin mass is first introduced into the internal space. The rotor is thereafter heated and run up to centrifuging rotational speed. As a result, the molten resin mass flows through the channels to the region of the permanent magnets and fills up all the cavities present there and also cracks which form in the brittle permanent magnets on running up to speed. The resin mass hardens while the rotor is kept at centrifuging rotational speed. Each surface region of the permanent magnets is thus reliably protected against corrosion.

    Abstract: A gas transfer machine for use as a vacuum pump, for example, has a pump rotor mounted on a rotatable shaft for transferring a gas, and a reluctance-type motor for rotating the rotatable shaft. The reluctance-type motor has a stator, a motor rotor surrounded by the stator, and a shield member isolating the stator from the motor rotor. The motor rotor is directly coupled to the rotatable shaft and has a plurality of magnetic salient poles.

    Abstract: An annular member 51 is fitted to the outer periphery of the stator cores in a rotating electric machine. The rotating electric machine has a cooling passage 29 in an axial direction between a resin molded section 50 and adjacent stator cores 20. The annular member 51 is formed from a material which has a larger coefficient of linear expansion than the magnetic material comprising the stator cores. At low temperatures, stress resulting from the differential between the coefficient of linear expansion of the stator core and the resin molded section is reduced because an inward compressive force is applied to the stator core by the annular member as a result of the difference in the coefficient of linear expansion.

    Abstract: A stator structure is provided with a stator core having a plurality of cooling passages or slots and an annular resin layer formed on an inner peripheral surface of the stator core that defines a rotor receiving opening. The stator core has a plurality of protrusions disposed on the inner peripheral surface of the stator core to control the depth of the annular resin layer formed on the inner peripheral surface of the stator core. The protrusions have radial thicknesses that are substantially equal to the radial thickness of the annular resin layer.
