    Abstract: A blower includes an impeller housing, an impeller rotatably secured to the housing and an electric motor. The motor has a motor housing with a central portion and a radially extending portion extending from the central portion, a venturi chamber adjacent the motor housing and opposed to the impeller housing, a stator secured to the central portion of the motor housing, a rotor rotatably secured to the central portion of the housing, and at least one heat generating electrical component secured to the radially extending portion of the motor housing. The impeller housing has a first air pressure therein and the motor housing has a second air pressure therein different that the first air pressure. The venturi housing and the motor housing define a passageway therebetween whereby the difference in air pressure generates air flow within the motor housing to cool the at least one heat generating electrical component.

    Abstract: An axial flux electric machine has a rotatable shaft, a fixed stator core comprising a ferromagnetic material and defining an axis of rotation, and a rotor assembly comprising a plurality of permanent magnets. The rotor assembly is rotatable about the axis of rotation. An axial air gap is defined between the stator core and the rotor assembly. The rotor assembly is axially displaceable towards and away from the stator core. The rotor assembly has a first position wherein the axial gap is a predetermined width greater than zero, and a second position wherein the axial gap is zero, such that the rotor assembly and the stator core contact each other.

    Abstract: A fluid circulating assembly having a rotation axis is provided. The fluid circulating assembly includes a fan impeller including an inlet ring and a rear plate that together define a central fan chamber. The fluid circulating assembly also includes an electrical machine having a rotor assembly, a stator assembly, and at least one bearing assembly. The rotor assembly is coupled to the rear plate such that the electrical machine is located entirely outside the central fan chamber. The rotor assembly includes a hub portion having a radially inner wall that at least partially defines a central opening extending entirely through the electrical machine and oriented about the rotation axis such that the central opening does not include a shaft extending therethrough.
