STATOR TORQUE RETENTION FEATURE FOR A CAST-IN STATOR ASSEMBLY

摘要

An electric machine is disclosed having a stator and a rotor, the stator comprising one or more windings that "turn" between passes through the stator. The turn portions of the windings are cast within a heat-conductive material such as aluminum that conducts heat away from the turn portions. The casting also defines a cavity for the flow of a heat-carrying fluid (such as water) to remove heat more efficiently from the turn portions. In some embodiments, the windings are electrically insulated (for example, using a ceramic insulator) before the casting.
