Abstract
A gap seal for an electric machine having a rotor rotatable about a rotation axis and separated from a stator by an annular gap. The gap seal includes an annular body defining a radial ring and an axial ring joined to the radial ring as a unitary part. The radial ring extending in a radial plane and the axial ring extending in a direction of the rotation axis. The radial ring and the axial ring each define an inner surface, the inner surface of the axial ring is configured and positioned to abut an annular axial peripheral surface of the rotor and provide a sliding seal, and the inner surface of the radial ring is configured and positioned to abut a radial peripheral surface of the stator and provide a static seal, wherein the sliding seal and the static seal cooperate to provide a liquid-tight seal of the annular gap.
