Publication number: 20220368196Abstract: 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.Type: ApplicationFiled: July 27, 2022Publication date: November 17, 2022Applicant: Nidec Motor CorporationInventors: Richard L. Eason, Michael L. Largent, Steven R. Palmer, Jeffrey Scott Sherman, Richard A. Belley

Patent number: 11063495Abstract: A clamp assembly is operable to engage at least three heat-generating electrical components arranged side-by-side and clamp the electrical components relative to a heat sink. The clamp assembly includes a clamp bar and a fastener to secure the clamp bar to the heat sink. The clamp bar includes at least three spaced apart projections configured to be located in engagement with the respective electrical components. The clamp bar presents a slot positioned between a spaced apart pair of the projections and defines respective clamp bar sections on opposite sides thereof. The slot permits the clamp bar sections to shift relative to one another and thereby facilitate clamping engagement of the projections with the electrical components.Type: GrantFiled: July 1, 2019Date of Patent: July 13, 2021Assignee: Nidec Motor CorporationInventors: James L. Skinner, Richard A. Belley, Michael L. Largent

Publication number: 20210006190Abstract: 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.Type: ApplicationFiled: July 1, 2019Publication date: January 7, 2021Applicant: Nidec Motor CorporationInventors: Michael L. Largent, Steven R. Palmer
