  • Patent number: 11532959
    Abstract: An electric submersible pump (ESP) that has a motor section for driving the ESP. The motor section has a stator has an inner surface, winding channels disposed axially therein and windings disposed in the winding channels to generate an electromagnetic field when power is supplied to the ESP. The motor section also has a rotor rotatably disposed in the stator. The rotor has permanent magnets or induction windings disposed therein that are responsive to the electromagnetic field to facilitate rotation of the rotor relative to the stator. The motor section also includes a manipulated air gap disposed between the rotor and the stator that the electromagnetic field crosses. The manipulated air gap provides a desired constant radially directed load on the rotor to stabilize the rotor when instability of the motor section occurs. A method of designing and constructing the ESP disclosed herein.
