Abstract
A stator core for an electric machine includes a stator tooth for mounting an electromagnetic coil and a cooling structure associated with the stator tooth. The cooling structure has multiple sections adjacent each other along a direction parallel to the axis of the stator core. Each section includes multiple channels for the flow of a coolant. The plurality of channels are spaced azimuthally from each other and are arranged asymmetrically about the stator tooth. Adjacent sections of the cooling structure along the axis of the stator core are substantially identical to each other and are rotated 180 degrees about a radial direction relative to each other.
