Abstract
A stator winding includes a plurality of conductors including ducts. The ducts can be connected to a heat pipe or a conduit providing a coolant flow to directly cool the winding. The heat pipe can be connected to a heat exchanger that includes a coolant flow. The stator winding can be produced using additive manufacturing, with hollow ducts extending through leg sections and solid end sections. The heat exchanger can also be additively manufactured. A circuit for driving an electrical machine can be in thermal communication with the heat exchanger, such that the thermal system manages both the stators and the drive circuit.
