  • Patent number: 4999532
    Abstract: An electric motor comprising a stator having radially inwardly extending circumferentially spaced polar segments and a plastic support on each axial end of the stator. Each support has substantially the same configuration as the cross sectional configuration of the ends of the stator, including segments overlying the segments of the stator. Each segment includes an axially outwardly extending wall, and a coil is wound around each stator segment and segment of said support. Integral strain relief portions are provided on each support for connecting the coils and for connecting power leads to the ends.

  • Patent number: 4529901
    Abstract: An electric motor comprising a lower housing, and an upper housing. The lower housing comprises a hollow stationary shaft, and a stator mounted on the shaft. The upper housing comprises, a tube rotatably mounted on the shaft and a rotor fixed on the tube and surrounding the stator for rotation about the shaft. A thrust bearing is interposed between the end of the tube and the lower housing. Longitudinally upper and lower spaced bearings are interposed between the tube and the hollow shaft. An oil holding element is interposed between the bearings. An oil sump means is provided in the lower housing associated with the lower bearing such that oil flowing out of the holding element collects in the oil sump.

  • Patent number: 4505031
    Abstract: The method of assembling an electric motor which comprises forming an upper housing assembly by first forming a generally cylindrical shell, forming an end member with an axial tube, mounting the end member on the cylindrical shell with the tube extending axially inwardly, locating the shell radially in an accurate position with respect to the axis of the shell, fastening the end member to the shell to form an upper housing assembly, mounting a radial wall on a hollow shaft, accurately locating a stator on the radial wall so that the stator and the outer diameter of the shaft are in accurate concentric relationship, fixing the stator in this accurate position to form a lower housing assembly, telescoping the upper assembly over the shaft of the lower housing assembly and interposing bearings between the shaft and the tube so that the upper housing assembly is in accurate concentric relationship with the stator.
