Abstract
Described herein are immersion-cooled axial flux electric motors and methods of operating thereof. An immersion-cooled axial flux electric motor comprises a rotor and an immersion-cooled stator. The rotor comprises a set of magnets and a magnet support plate extending perpendicular to the motor axis. The set of magnets is attached to the magnet support plate and distributed about on the motor axis. The immersion-cooled stator comprises a cooling-fluid inlet, a cooling-fluid outlet, a set of stator windings, and a stator-sealed space. The set of stator windings is positioned within the stator-sealed space proximate to the set of magnets such that during the operation of the motor magnetic flux between the set of stator windings and the set of magnets is aligned substantially parallel to the axis of rotation of the rotor. The cooling-fluid inlet and the cooling-fluid outlet are fluidically coupled to the stator-sealed space.
