Abstract
An electric motor includes a stator having a plurality of conductive windings radially spaced about a central axis. A rotor is located radially inward up the stator and is rotationally fixed with respect to a shaft along the central axis. The rotor and the stator are disposed in a frame. A heater is in operative communication with the windings. A thermostat is in operative communication with the heater and is configured to activate and deactivate the heater responsively to a motor temperature.
