Abstract: A bearing assembly cooperates with a bearing seat formed in a bearing housing and includes a bearing having an inner ring, an outer ring and a rolling element in engagement with the rings and an anti-rotation device. The anti-rotation device engages the outer ring to the bearing housing limiting rotation of the outer ring within the bearing seat. The anti-rotation device includes a first feature engaging the outer ring and a second feature engaging the bearing housing. The features limit the rotation of the outer ring within the bearing seat. The first feature has an internal surface for engagement the outer ring and the second feature includes an engagement surface for engaging a protrusion extending from the bearing housing.

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 terminal board assembly for a multi-voltage device. The terminal board assembly includes a terminal board including a terminal block. The terminal board is configured for attachment to the multi-voltage device. The terminal block is configured to electrically couple with an electrical power source and the multi-voltage device. The assembly also includes a plug that is configured for insertion within the terminal block. The terminal block is configured to receive the plug in at least one of a first inserted position and a second inserted position. The orientation of the plug relative to the terminal block is the same in the first inserted position as in the second inserted position. The terminal block is configured to transfer a first voltage to the multi-voltage device when the plug is attached to the terminal block in the first inserted position.

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: A mounting bracket for a motor run capacitor includes a capacitor clasp which extends from a base to the motor run capacitor. The mounting bracket further includes a U-shaped member which attaches the bracket to a motor shell. The bracket also includes a tab which connects to a tab coupling on the shell. The motor shell includes a slot and a circular opening for engaging the U-shaped member and a circular projection on a lock of the mounting bracket, respectively.

Abstract: An electric motor has a housing including a frame and first and second end shields disposed adjacent opposing ends of said frame to define a motor compartment. A stator winding is mounted on the housing within the motor compartment and includes at least first and second main windings. An armature is rotatably mounted on the housing within the motor compartment in spaced relation to the stator winding. A voltage selection switch, which is moveable between first and second positions, is mounted on the first end shield to allow the motor to be run at high or low voltage settings. The first end shield also includes a silicon-grease filled tubular seat which reduces the transfer of contaminants into the motor compartment.

Abstract: A speed reduction switch for a multiple speed induction motor includes a speed selector switch and a delay element. As the motor is switched from a high speed to a lower speed, the delay element temporarily prevents electrical connection of a motor auxiliary winding for low speed operation. The motor is therefore de-energized and slows down. After a preselected delay, the delay element connects the motor auxiliary winding when the motor is at a lower speed so that little magnetic braking of the motor occurs, and the motor smoothly transitions from a higher speed to a lower speed.

Abstract: Systems and apparatus for integrating an air switch and a power cord into an electric motor, and methods for assembling an electric motor including an integral air switch and an integral power cord, are described. In one embodiment, an air switch and a power cord are incorporated into an electric motor. No additional removable cover is required for the switch and cord. To eliminate the motor centrifugal switch, an air switch is provided to control energization and de-energization of the motor windings. The air switch includes a snap action switch to cut-out the start winding used for ensuring that the rotor has sufficient starting torque.

Abstract: An air compressor system having an actuator for controlling the energization of the primary and start windings of the compressor motor and the state of a relief valve is disclosed. No power is applied to either of the windings and said valve is closed when the actuator is disposed in the first position. Movement of the actuator to the second position energizes both of the windings and opens the relief valve so that the motor and compressor can reach full speed before a load is applied. When the actuator is released and moved to the third position, the start winding is deenergized and the relief valve is closed to allow an air storage tank to be filled.
