  • Regenerative dynamometer for use with an electrical submersible pump
    Patent number: 12590530
    Abstract: A dynamometer is used to dynamically evaluate an electrical submersible pump (“ESP”) motor while both are inside of a well. The dynamometer includes a ESP dyno that is mechanically coupled to the ESP motor. The ESP motor and ESP dyno can be a permanent magnet motor or an induction motor, and can have the same or similar values of inertia. Energy absorbed by the ESP dyno can be regenerated as electricity that is transmitted back to a power source, or converted to heat energy in a resistive load bank.
