摘要： 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. To design and construct the ESP, a desired constant radially directed load is determined for an electric submersible pump (ESP) to stabilize the ESP when instability of an electromagnetic field of the ESP occurs. The air gap is manipulated to achieve the desired constant radially directed load or the design of a stator of the ESP is manipulated to achieve the desired constant radially directed load. The ESP can then be constructed.

摘要： An ESP including a motor section for driving the ESP. The motor section includes a stator with winding channels disposed axially therein and windings disposed in the winding channels to generate a stator electromagnetic field. The motor section also includes a rotor rotatably disposed in the stator. The rotor having a body with multiple permanent magnets to generate a constant magnetic field and rotor bars disposed axially in the rotor that cause an induced electromagnetic field when subjected to the stator electromagnetic field. Alternatively, the rotor includes multiple permanent magnets to generate a constant magnetic field wherein the stator electromagnetic field and the constant magnetic field create a two pole magnetic field for the motor section. A method of determining a layout of multiple permanent magnets disposed axially in a rotor to generate a desired constant magnetic field and produce a two pole magnetic field for the ESP and constructing the ESP.
