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.

In one embodiment, a permanent magnet rotor for use with a stator is provided. The permanent magnet rotor includes at least one permanent magnet and a substantially cylindrical rotor core including an outer edge, a hub having an inner edge defining a central opening, and a plurality of independent pole pieces spaced from the hub radially about the central opening. The rotor core further includes at least one radial aperture extending radially from the outer edge through the rotor core between adjacent independent pole pieces, the at least one aperture configured to receive the at least one permanent magnet.
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.
