Abstract: An electric motor comprises a rotor and a stator having a yoke. The yoke includes a plurality of teeth mounted to the yoke and being aligned substantially parallel to an axis of rotation of the motor, each tooth including a first radial end adjacent to the yoke and a second radial end extending from the yoke, a plurality of field coils, each field coil being wrapped around a tooth, and a coolant circulation path including a first coolant channel defined between adjacent field coils and a second coolant channel defined between adjacent field coils and between the first radial ends of adjacent teeth. A third coolant channel may be defined between adjacent field coils and between the second radial ends of adjacent teeth.
