  • Negative pressure motor sealing
    Patent number: 9929625
    Abstract: A system includes an electric motor including a housing enclosing a substantially-sealed internal environment, a pump including an inlet connected to the substantially-sealed internal environment of the electric motor via a first conduit, and a fluid supply storing a makeup fluid, the fluid supply including an outlet connected to the substantially-sealed internal environment of the electric motor via a second conduit. The pump is configured to create a negative pressure within the substantially-sealed internal environment of the electric motor to mitigate potential contamination of an external environment of the electric motor with the makeup fluid.
