Abstract: An apparatus includes a lamination stack for a motor stator. The lamination stack comprises a plurality of conductive laminates. The laminates are coupled to each other in a stacking direction along a stacking axis. 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.
