Abstract

An electric machine includes a rotor configured to rotate about an axis of rotation, a stator having a plurality of teeth annularly arranged on a stator core about the axis of rotation, a plurality of electromagnetic coils, and a base plate. Each coil of the plurality of electromagnetic coils may be mounted on a separate tooth of the plurality of teeth, and the base plate may be located adjacent to the plurality of electromagnetic coils and the stator core. The base plate may be in thermal contact with the plurality of electromagnetic coils and the stator core such that as the plurality of electromagnetic coils and the stator core heat during operation, the base plate is configured to serve as a common heat sink for the plurality of electromagnetic coils and the stator core.
