Power steering motor

An electric machine includes a stator with a plurality of circumferentially-spaced stator segment assemblies. A rotor rotates relative to the stator and defines an airgap between an outer diameter of the rotor and the inner diameter of the stator. Each stator segment assembly includes a stator segment core, an endcap that is attached to the stator segment core, and winding wire that is wound around the endcap and the stator segment core. The endcap provides first and second axial mating surfaces. The endcaps provide first and second circumferential surfaces on opposite axial ends thereof. First and second annular seals engage the first and second circumferential surfaces to provide circumferential seals at opposite axial ends of the stator. The annular seals, the axial seals and the circumferential seals prevent the entry of debris into the airgap.
