Abstract: A cooling device includes a body formed into an elongate strip having upper and lower surfaces. The elongate strip is configured to contact the housing along the lower surface for conductive heat transfer from the housing to the body. Each of a plurality of cooling fins is attached to the strip and extends from one end attached to the upper surface of the strip another, free end. The device includes a first tab disposed at one end of the elongate strip, and a second tab disposed at another end of the elongate strip. The elongate strip is made from a compliant material such that the elongate strip conforms to a shape of the housing when the first and second tabs are connected to the housing and a majority of the lower surface contacts the housing. The fins are arranged to convectively dissipate heat from the body.

Abstract: A rotor of a synchronous reluctance motor may include: a plurality of laminations forming a stack, each lamination including: two parallel surfaces and a perimeter that define the lamination and a direction of stacking the laminations that is perpendicular to the parallel surfaces, the lamination at least partially filled with a magnetically soft electrical conductor and at least one cavity encircled by the conductor and extending from a first to a second surface of the two parallel surfaces, the conductor forming at least one bridge at the perimeter of the lamination from one side of the at least one cavity to another side of the at least one cavity. A value of a magnetic property and a value of a mechanical property of the at least one bridge differs from a value of the magnetic property and a value of the mechanical property of the conductor material.

Abstract: A transmission includes a housing, a plurality of components, and a cooling system. The housing has a plurality of walls that cooperate to define an interior space and a sump configured to store lubricating fluid in use of the transmission. The plurality of components are arranged in the interior space and configured to cooperatively transmit rotational power between an input shaft and an output shaft of the transmission to reduce a rotational speed of the output shaft relative to a rotational speed of the input shaft in use of the transmission. At least one of the plurality of components is supplied with lubricating fluid stored by the sump in use of the transmission. The cooling system is supported by the housing.

Abstract: A mechanical drive system includes a mechanical drive component, an enclosure, and a centrifugal fan. The mechanical drive component has a housing and a rotatable shaft supported within the housing. The enclosure is disposed on the housing and a wall of the housing has an output opening therein through which the rotatable shaft of the mechanical drive component extends and another of wall has an intake opening therein. Surfaces of the housing and the walls of the enclosure define an air passage channel extending from the intake opening to the output opening. The centrifugal fan is aligned and in fluid communication with the output opening of the enclosure. The impeller is operatively connected to the rotatable shaft.
