1. A wet cavity electric machine comprising:

  • a stator core having at least two stator poles formed by a set of stator windings, with the stator winding having end turns;

    a rotor having at least two rotor poles, and configured to rotate relative to the stator core, and having a channel for liquid coolant to flow through the rotor to at least one nozzle;

    at least one oscillating heat pipe received within the set of stator windings and having an evaporator portion extending through the stator core and a condenser portion extending axially past the stator core proximate to the at least one nozzle, and wherein the evaporator portion and the condenser portion are positioned between sealed opposing ends of the at least one oscillating heat pipe; and

    a working fluid in the at least one oscillating heat pipe, wherein the working fluid is disposed in alternating liquid and vapor phases in the at least one oscillating heat pipe;

    wherein liquid coolant from the at least one nozzle can be sprayed onto the condenser portion of the at least one oscillating heat pipe to cause the working fluid to oscillate and extract heat from the stator core.
