Abstract:
Embodiments of the present disclosure are directed toward a sealing system for a motor that includes a first sealing element configured to be circumferentially disposed around a rotor shaft of the motor. The sealing system also includes a second sealing element configured to be circumferentially disposed around the rotor shaft. A sealing tip of the first sealing element is configured to lift from a surface of the rotor shaft in response to a pressurized fluid directed between the first sealing element and the second sealing element. Additionally, the first sealing element and the second sealing element are configured to radially float around the rotor shaft.
