  • Publication number: 20150091396
    Abstract: A mounting feature plate rigidly mounts a mounting feature to a stator of an electrical motor in proximity to an end shield to help maintain a predetermined air gap between a rotor and a stator in the electrical motor. The mounting feature plate includes a planar member, an offset member extending from the planar member that has a mounting feature configured to mount an electrical motor within an appliance, and a pair of flanges extending from the planar member. Each of the flanges has an opening with a cylindrical extrusion aligned with and extending from the opening. The extrusions are configured to be received within a mounting hole within a stator to enable a bolt to pass through the opening and the extrusion and be received within the mounting hole in the stator.

  • Patent number: 8994245
    Abstract: The permanent magnet type electrical rotating machine has an overhung rotor support structure in which a shaft of a rotor is supported at only one end side thereof by a bearing provided on one side of a casing of the electrical rotating machine. Another end side of the rotor shaft to be a bearing support-free side is capable of being joined to an end of a shaft of a prime mover via a flange formed at an end of the shaft. The rotor shaft is configured such that, upon a state of not being coupled to the prime mover shaft, the flange on the bearing support-free side is joined to an end face of the casing through a retaining member to be prevented from moving in any of an axial, radial and circumferential directions of the rotor shaft.
