Abstract: A housing for a motor is described. The housing extends between a pair of endshields and includes an inner surface, an outer surface, and at least one raised projection extending outwardly from at least one of the housing inner and outer surfaces. The projection includes at least one opening extending therethrough and at least one fastener configured to attach to the inner surface and extend outwardly through the housing opening.

Abstract: A sump pump motor switch assembly for a sump pump including a motor casing and an end shield, includes a switch assembly and a housing mounted to the end shield. A cam actuator is connected to the housing and a sump pump actuation switch is mounted with the cam actuator. A motor actuation switch is also mounted with the cam actuator body. The sump actuation switch and the motor actuation switch are snap action switches that are simultaneously actuated by the cam actuator. The switch assembly includes a snap fitting assembly configured to fit into a receiving retainer within the motor casing.

Abstract: A bearing load washer that permits assembly of electric motors with the rotor shaft in a vertical position and extending downward is described. The bearing load washer includes a plurality of portions that form a non-planar, wave shaped, substantially circular shaped, washer body. The washer includes a center opening that is sized so that an electric motor rotor shaft can extend through the washer body. The washer includes an outer circumferential surface and at least one raised area extending radially from the outer circumferential surface. The raised areas are configured to increase the outside diameter of the washer so that the outer circumferential surface engages the inner surface of an endshield bearing pocket at each raised area of the outer circumferential surface.

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.

Abstract: An electric motor assembly including an integral tray for placement of tools and accessories is disclosed. The tray includes a plurality of compartments having a variety of shapes and sizes. A first portion of the tray is connected to a cover and the tray extends from the cover along a portion of the electric motor. A second portion of the tray is perpendicular to the cover and includes an open top which allows tools and accessories to be placed within the compartments.

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.

Abstract: An electric motor assembly capable of withstanding heavy side loading includes a motor housing having a shell with first and second end shields including bearing supports having bearings therein. The first end shield further includes a flange for connecting a compressor to the motor. A rotor is rotatably mounted in the housing and supported by the bearings. A stiffening collar, positioned between a rotor core and the first end shield, surrounds a portion of a rotor shaft and provides support for the shaft against deflection due to heavy side loading. A centrifugal mechanism and a spacer are positioned on the rotor assembly outboard of the motor housing. The motor assembly also includes a cover attached to the second end shield. The cover holds a start capacitor, a run capacitor and a centrifugal switch and further includes snaps for mounting the centrifugal switch to the cover. An overload and an overload bracket extend, at least partially, through an opening in the second end shield.

Abstract: An air switch assembly for an electric motor including a first snap action switch, a second snap action switch, and an actuator, is described. The first snap action switch is connected to the motor start winding and the second snap action switch is connected to the run winding. An actuator is positioned within the air switch assembly such that the air switch energizes the start winding, energizes the run winding, and de-energizes the start winding while maintaining the run winding energized when the actuator is actuated from an initial position to a final position.

Abstract: A weldment for attaching mounting brackets and bases to electric motors includes an internal doubler element that is positioned within a motor shell and attached to the inner wall surface of the motor shell. A mounting bracket or base positioned on the outer wall surface of the motor shell is attached to the internal doubler element by a plug weld. The internal doubler element is positioned to increase the strength of the shell at critical stress areas. In addition to utilizing the internal doubler element, the mounting bracket is positioned to be aligned with and adjacent the lap weld seam of the motor shell.
