Abstract
A motor housing assembly is formed by positioning a stator relative to a motor housing to configure a fillable gap between the stator and the motor housing, and filling the fillable gap is at least partially with a polymeric material to form a thermally conductive layer. The polymeric material may include a metallic filler material. The thermally conductive layer is in contact with an exterior surface of the stator and an interior surface of the motor housing adjacent the exterior surface of the stator, and is configured to cover at least half of the exterior surface. A method to form the thermally conductive layer includes injecting a high flow polymeric material through a port defined by the housing and in fluid communication with the fillable gap.
