Abstract
An electric machine includes a cylindrical stator core and a cylindrical housing having an inner diameter. The core has an outer surface and a plurality of projections extending therefrom. An outer diameter of the core measured between tips of diametrically opposing projections is greater than the inner diameter. The core is disposed in the housing with the tips engaging the inner diameter to create an interference fit between the core and housing to reduce housing resonance.
