  • Patent number: 6657338
    Abstract: A motor including a first compartment, a second compartment, a frame, a first end shield, a second end shield, an armature shaft, a stator winding, an armature, a cover, and a switchboard is provided. The first and second end shields are disposed adjacent opposing ends of the frame to define the first compartment. The armature shaft extends between the first and second end shields. The stator winding is supported by the frame within the first compartment. The armature is rotatably supported by the end shields and disposed within the first compartment adjacent the stator winding. The cover includes a first end, a peripheral edge, and ventilation openings. The cover peripheral edge is mounted to the motor adjacent the second end shield. The ventilation openings include a plurality of openings positioned along at least part of the cover peripheral edge and in the cover first end.

  • Patent number: 6252321
    Abstract: An endshield assembly for an electric motor is described. The endshield assembly includes a metal endshield, a bearing assembly, and an injected molded metal center housing that couples the bearing assembly to the metal endshield. The bearing assembly includes a cylindrical housing having an outer surface. The center housing includes a cylindrical wall having an inside surface and a plurality of projections extending from the inside surface of the cylindrical wall. The projections are positioned around the circumference of the inside surface of the center housing to engage the outer surface of the bearing housing. The projections are staggered about the center housing circumference so that every projection contacts the outer surface of the bearing housing on an opposite side of a bearing housing circumferential centerline than an immediately adjacent projection.

  • Patent number: 6220901
    Abstract: A terminal board assembly for an electric motor is described. The terminal board assembly is configured to mount inside an electric motor terminal or conduit box and includes a terminal board and a mounting bracket. The terminal board includes six terminal studs and three connecting bars extending between the terminal studs. Quick connect spade type connectors are coupled to the six terminal studs adjacent the bottom of the terminal board to facilitate quick and easy connection of the wire connection leads of an electric motor. The terminal studs and connecting bars permit a choice of “Y” or “Delta” voltage connections to the electric motor. The terminal board also includes a first and a second slot positioned at, and parallel to, opposing ends of the board. The mounting bracket includes a base portion and first and second side portions depending from opposing ends of the base portion.
