Abstract: A throughflow motor assembly includes a motor assembly having a rotatable shaft and a housing with a motor assembly mounted to one end and a housing opening therethrough. A fan assembly is rotated by the rotatable shaft and received in the housing at an end opposite the motor assembly. The housing includes a partition which partitions the fan assembly and the motor assembly from one another, and includes at least one centrally located flow passage extending therethrough. The fan assembly draws air over the motor assembly, through the housing opening and at least one centrally located flow passage, and then into the fan assembly which exhausts the air.

Abstract: An appliance provides a platform having a platform bottom and a platform base which supports a main base. A motor is carried by the platform base and rotates a ventilation fan which has a plurality of radial vanes with a fan aperture centrally positioned therein, such that the ventilation fan draws air in through an intake port provided by the platform. A fan shroud encloses the ventilation fan and has a shroud opening. The fan shroud extends from the platform base toward the platform bottom, wherein the main base surrounds the motor. The main base has an outer housing with at least one housing port, wherein rotation of the ventilation fan draws air into the fan aperture from the intake port, through the shroud opening, and expels the air radially from the plurality of radial vanes so that the air flows through the motor and out the housing port.

Abstract: A motor-fan assembly includes a motor assembly having a tubular core with a rotatable shaft extending therethrough. The assembly includes a working fan assembly which has at least one working fan rotated by the rotatable shaft. A blower housing separates the motor assembly from the working fan assembly, wherein the rotatable shaft extends through the blower housing.

Abstract: An appliance includes a reverse air flow motor housing. A casing carries and supports a motor, and a ventilation fan is rotated by a rotatable shaft driven by the motor. A lower platform with an air intake port carries a ventilation shroud that partially encloses the ventilation fan. An inner support is mounted between the lower platform and the casing. An outer housing has a sidewall that substantially encloses the motor and is supported by the lower platform. Rotation of the ventilation fan draws in ambient air through the air intake port which then proceeds between the casing and the motor and subsequently through the sidewall port.

Abstract: A fan/motor assembly having an integrated brush support and bearing retainer is disclosed. The fan/motor assembly includes a rotatable shaft, a working air fan coupled to the shaft, and a motor bracket and baffle assembly interposed between the working air fan and the motor assembly. The motor bracket and baffle assembly retains a bearing which rotatably receives the shaft and provides integral brush boxes for the motor assembly.

Abstract: A combined commutator brush retainer clip and electrical connector includes a main body portion and a terminal portion. The main body portion has a recessed portion with a plurality of dimples therein. A commutator brush is electrically connected to a brush holder sleeve, and the brush holder sleeve is, in turn, clampingly engaged to the commutator housing with the retainer. The brush holder sleeve is disposed within the recessed portion of the retaining clip and is frictionally engaged by the dimples. The terminal portion of the retainer engages a corresponding terminal member on the motor stator such that an electrical connection is established between said commutator brush and said stator by way of said retainer.

Abstract: A brush holder clip and connector for motors and generators is provided in the form of an integral V-shaped spring steel member having an electrical connector extending from one of the legs thereof and opposite an apex of the clip and connector. The housing containing the commutator has a slot therein through which the brush holder passes. The V-shaped clip and connector is inserted into the slot and wedged between the brush holder and an edge of the slot. The clip and connector is electrically conductive and communicative with the brush holder 22 and is adapted for mating interconnection with a wire or other conductor.
