Abstract: An electric motor assembly includes a housing and a stator. The housing includes an outer housing surface, an inner housing surface defining an interior housing cavity, and a plurality of housing protrusions extending from the inner housing surface. The stator is disposed in the inner housing cavity and includes an outer stator surface, an inner stator surface, and a plurality of stator protrusions extending from the outer stator surface toward the outer housing surface. The stator protrusions are configured to mate with the housing protrusions to frictionally couple the stator to the housing in order to fix the stator relative to the housing.
