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.
