A system, comprising:
- a submersible actuator, comprising:
- a first electric motor;
- a second electric motor;
- a control circuit configured to control the first and second electric motors to actuate a submersible flow control mechanism;
- a first container holding the first and second electric motors, wherein the first container is filled with a liquid;
- and
- a second container holding the control circuit, wherein the second container is filled with a gas.
4 more elements
A system, comprising:
- a submersible actuator, comprising:
- a first electric motor;
- and
- a control circuit configured to control the first electric motor to actuate a submersible flow control mechanism, wherein the control circuit is configured to control a speed and a direction for rotation of the first electric motor based on a first feedback indicative of an actuator position and a second feedback indicative of an absorbed current.
