COOLING ASSEMBLIES FOR OUTER ROTOR ELECTRIC MOTORS

Cooling assemblies for outer rotor electric motors are disclosed. An example electric motor includes a stator, a rotor, and a heat exchanger. The stator has a central axis. The rotor circumscribes the stator. The rotor is configured to rotate relative to the stator. The heat exchanger is coupled to the stator. The stator circumscribes the heat exchanger. The heat exchanger includes a plurality of fins extending in a radially inward direction away from the stator and toward the central axis. In some examples, the fins are circumferentially oriented. In other examples, the fins are axially oriented. In still other examples, the fins are helically oriented.
