Each laminate comprises a base, a plurality of fins extending from a first side of the base, a plurality of spacings between the fins, a row of teeth extending from a second side of the base opposite the first side, each tooth constructed and arranged to communicate with windings of a conductive coil, and a plurality of spacings between the teeth. The lamination stack also comprises a plurality of first channels formed from the spacings between the fins and a plurality of second channels formed from the spacings between the teeth. The first and second channels extend along the stacking axis.
