Abstract
A motor assembly comprising a stator including: a yoke with an axial end surface, an integral tooth extending radially inward from the yoke, and a segmented tooth extending radially inward from the yoke. The motor assembly further comprises a winding wound around the integral tooth; and a cap positioned at the axial end surface. The cap includes a rim portion aligned with the yoke and a tooth portion aligned with the segmented tooth. The cap is a thermal conductor and an electrical insulator, and the cap provides a thermal conduction path to extract heat from the end winding portions of the stator windings.
