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.

The bearing cap is selected from the plurality of bearing caps as a function of a width of the stator core. The invention is also a motor system that includes a stator core selected from a plurality of stator cores and a bearing cap selected from a plurality of bearing caps. Each of the plurality of stator cores has a different stator core width and each of the plurality of bearing caps has a different bearing cap length. The bearing cap is selected as a function of a width of the selected stator core.

Abstract: A lubricant retention assembly is employed with an electric motor to prevent the loss of lubricant from a self contained lubricant reservoir of the motor. The lubricant retention assembly includes a thrust collar mounted on the motor shaft and a bearing cap surrounding the thrust collar, where the thrust collar has an annular flange that throws lubricant leaking along the shaft radially outwardly toward the bearing cap. The bearing cap has an angled interior surface that deflects the lubricant thrown from the annular flange of the thrust collar back into the motor interior and toward the lubricant reservoir. A thrust washer is also provided on the shaft adjacent the thrust collar and prevents lubricant leakage along the shaft between the interface of the shaft and the thrust collar. The thrust washer and thrust collar have complementary configurations that maintain the thrust washer in position on the shaft adjacent the thrust collar.

Abstract: A motor shaft bearing assembly restricts the pivoting or swiveling movement of a self-aligning bearing supporting a motor shaft in a bearing seat. The bearing assembly provides projections adjacent the bearing seat that engage with an exterior surface of the bearing to restrict the movement of the bearing relative to the bearing seat. As an alternative or in addition to the projection adjacent to the bearing seat, a bearing retainer holding the bearing against the bearing seat is provided with a projection that engages into the exterior surface of the bearing to restrict the movement of the bearing relative to the bearing seat.

Abstract: A mounting clip that attaches a circuit component to an electrical device attenuates vibration of the circuit component as the electrical device is operated. The mounting clip is designed for a thermo-protector of an electric motor and removably attaches the thermo-protector to a switch housing of the electric motor. The thermo-protector is connected in the circuit of the electric motor and wiring of the electric motor that communicates with the thermo-protector is attached to the mounting clip. The mounting clip is provided with a spring mechanism that engages an abutment provided on the switch housing and biases the mounting clip and the attached thermo-protector and thermo-protector wiring away from the switch housing and thereby attenuates vibration of the thermo-protector and its wiring.

Abstract: A lubricant leakage stop is provided on the shaft of a rotary device in the form of an annular groove in the shaft. In one embodiment the annular groove is formed with an annular inner surface at the bottom of the groove and with an annular intermediate surface positioned between two portions of the annular inner surface. The intermediate surface has a larger diameter dimension than the two inner surface portions on the axially opposite sides of the intermediate surface. The intermediate surface also has a smaller diameter dimension than that of the two portions of the shaft outer surface on axially opposite sides of the groove. In a second embodiment, the annular groove is formed with an annular inner surface that tapers from the bottom of the groove outwardly to the outer surface of the shaft on one side of the groove.

Abstract: A bearing retainer that holds a bearing in a bearing seat of an electromagnetic device has a unique construction that reduces its cost of manufacture. The bearing retainer has a peripheral edge with a plurality of radially extending tabs centered in gaps in the peripheral edge. The tabs connect with tabs of adjacent bearing retainers, allowing a plurality of interconnected bearing retainers to be nested on a steel sheet from which the retainers are stamped, thereby optimizing material use and reducing costs. The bearing retainers are composed of martensite which eliminates a heat tempering process required of prior art retainers and further reduces costs.

Abstract: A dynamoelectric machine includes a stator assembly and a rotor assembly, including a rotatable shaft ad a rotor affixed to and rotatable with the shaft. The stator and rotor assemblies are assembled into a motor and the motor has the stator and rotor insulated from electrical contact with other objects. Because of its construction and design, the motor does not require electrical grounding prior to use so that it is not a hazard to persons coming into contact with it in its application.

Abstract: A dynamoelectric machine has a rotor affixed to a shaft which is journaled at each end by a bearing assembly. These elements preferably are assembled in a housing. A simplified system for controlling end movement or end play of the shaft during transport of the motor and motor start-up and coast-down eliminates the need for end play washers normally associated with motor construction. The system includes a stop (3) molded into an endshield of the motor so as to be integrally formed in one end wall of the housing, while a spacer (7), which can bear against the bearing at the other end of the shaft restrains end play in the opposite direction.

Abstract: A dynamoelectric machine comprises a housing (H), a rotatable shaft (S) installed in the housing and a bearing (B) in which the shaft is journaled. The bearing is installed in the housing adjacent each end wall (W) thereof. A bearing retainer (3) fits over the bearing and contacts an inner portion (7) of the end wall to hold the bearing in position. The retainer includes fingers (21) for self-aligning the retainer with the bearing and for maximum control and flow of lubricant along each end and outer surface of the bearing.

Abstract: A dynamoelectric machine has a housing and a rotor assembly including a rotatable non-stepped shaft which projects through an opening in an end wall of the housing. A fan moves air through the machine to ventilate it and keep it cool. The fan is secured to an end of the shaft extending through the opening by a tab fitting in a groove formed in the shaft and a retention ring fitting over a hub portion of the fan in which the tab is formed.
