Abstract: Systems and methods include providing a tolerance ring in an electric drive motor assembly having a housing and a stator disposed within the housing. The tolerance ring is disposed within the housing and retains or secures the stator within the housing and control movement of the stator within the housing. The tolerance ring includes an annular ring-shaped substrate formed from a metallic material and a plurality of projections protruding radially inward from an inner surface of the substrate or radially outward from an outer surface of the substrate. The tolerance ring optionally includes one or more cooling features formed in the substrate and configured to promote cooling between a fluid disposed in the housing and the stator.
