Abstract: A rotor assembly for an electric motor includes a rotor core that is fabricated from a plurality of stacked laminations. The rotor core has a plurality of arcuately arranged, axially extending magnet receiving slots. The rotor core includes a plurality of magnets received in respective ones of the magnet receiving slots. The laminations include radially extending deflectable magnet retaining tabs that extend into the magnet receiving slots. The magnet retaining tabs engage and are deflected by a corresponding one of the magnets to exert a reactive force against the magnets.

Abstract: A motor assembly includes a motor, a controller controlling at least one aspect of operation of the motor, and a control housing defining a control chamber. The controller is in part received within the control chamber. The controller includes a main electronics board and a modular connector assembly. The modular connector assembly includes a secondary electronics board and a connector at least in part supporting the secondary electronics board. The connector includes an inner connector portion and an outer connector portion. The connector extends through the control housing such that the inner connector portion is disposed inside the control chamber and the outer connector portion is disposed outside the control chamber. The outer connector portion defines a first access portal facilitating access to a first component of the secondary electronics board.

Abstract: A motor controller assembly is configured for use with an electric motor and includes a controller and an absorbent pad. The controller includes a capacitor with a capacitor shell and a liquid electrolyte contained therein. The capacitor shell has a frangible rupture area that opens during a capacitor rupture event to permit the discharge of liquid electrolyte from the capacitor shell. The absorbent pad overlies the rupture area to collect discharged liquid electrolyte.

Abstract: An electric motor assembly includes a stator, a rotor, a motor housing, a rotatable shaft, a radial fan, and an air scoop. The motor housing at least partly houses the stator and rotor and presents an exterior motor surface. The rotatable shaft is associated with the rotor for rotational movement therewith, with the rotatable shaft extending along a rotational axis. The radial fan is mounted on the rotatable shaft exteriorly of the motor housing and is rotatable with the shaft to direct airflow in a radially outward direction. The air scoop extends radially outwardly relative to the radial fan and axially to receive radial airflow from the radial fan and turn the airflow axially to flow along the exterior motor surface. The air scoop includes spaced apart axially extending airflow vanes to guide the airflow as the airflow is turned axially.

Abstract: A motor control assembly is configured to operate an electric motor and includes a control housing and a controller. The control housing presents a controller chamber. The controller includes a control board mounted within the controller chamber. The controller further includes an inductor attached to the control housing and positioned within the controller chamber adjacent the control board. The inductor defines maximum first and second inductor dimensions measured along corresponding first and second directions parallel to a board plane and orthogonal to one another. The inductor further defines a maximum third inductor dimension measured along a third direction transverse to the board plane, with at least one of the first and second inductor dimensions being less than the maximum third inductor dimension.

Abstract: A motor includes a shaft presenting a shaft lead end, a switch assembly including a switch arm shiftable between a first position and a second position, and shield structure. The shaft lead end and the switch assembly are disposed axially outward of an endhsield. The shield structure is disposed axially outward of the switch arm to at least substantially restrict direct tool access to the switch arm from an axially outward position relative to the switch arm. The shield structure at least in part defines first and second tool access channels each extending radially inwardly to the shaft lead end, such that the shield structure enables direct tool access to the shaft lead end via the tool access channels but prevents or at least substantially restricts direct tool access to the switch arm via the tool access channels.

Abstract: A motorized pump assembly includes a pump and a motor for driving the pump. The pump includes a pump housing that at least in part defines a pump chamber. The motor includes a stator, a rotor rotatable about an axis, a motor housing, and a bearing assembly. The rotor includes a motor shaft extending along the axis.

Abstract: A location and retention component is provided for positively locating an overspeed guard and retaining a centrifugal actuator at an optimum positional relationship relative to each other. The system includes a first and second retention element removably engagable to the output shaft of a motor and axially fixable to the shaft at corresponding locations to maintain the optimum positional relationship. The first retention element serves as a positive stop for assembling the overspeed guard on the motor shaft, while the second retention element ensures that the centrifugal actuator is properly placed within the overspeed guard.
