Abstract:
A lubricant supported electric motor includes a stator and a rotor and a drive hub. The rotor is moveable relative to the stator and a gap is defined between the rotor and the stator. A lubricant is disposed within the gap to support the rotor relative to the stator and provide a bearing mechanism. The drive hub is coupled to the rotor such that rotation of the rotor causes rotation of the drive hub. The drive hub may be connected to the rotor via a coupler member that is torsionally stiff and axially and radially compliant. The stator may be fixed relative to a connection structure that extends radially within the stator. The connection member may support the drive hub for rotation. Lubricant is supplied via a passageway extending through the connection member into a chamber that includes the gap.
