Abstract:
A motor includes a rotor rotatable about an axis, a housing defining a motor chamber receiving at least a portion of the rotor, and a bearing assembly rotatably supporting the rotor on the housing. The housing includes a pair of axially spaced apart endshields. The bearing assembly includes a bearing and lubricant collection structure associated with the bearing. The lubricant collection structure defines a collection chamber configured to collect lubricant from the motor chamber and direct the lubricant to the bearing.
