Abstract
A motor for an electric submersible pump includes a rotor, a stator concentrically disposed around the rotor, and a main housing including a first lip having first threads. The main housing encloses a portion of the stator. The motor further includes a first extension housing including a second lip having second threads. The first threads engage the second threads to mate the first extension housing to the main housing. A first recess is formed in the main housing and the first extension housing at an interface between the main housing and the first extension housing. The motor further includes a first insert disposed in the first recess.
Claims22
A motor for an electric submersible pump, comprising:
- a rotor;
- a stator concentrically disposed around the rotor;
- a main housing comprising a first lip having first threads, wherein the main housing encloses a portion of the stator;
- a first extension housing comprising a second lip having second threads, wherein the first threads engage the second threads to mate the first extension housing to the main housing, and wherein a first recess is formed in the main housing and the first extension housing at an interface between the main housing and the first extension housing;
- and
- a first insert disposed in the first recess.
A method of assembling a motor for an electric submersible pump, comprising:
- screwing a first extension housing onto a main housing by engaging first threads of a first lip of the main housing with second threads of a second lip of the first extension housing, wherein the main housing encloses a portion of a stator, and wherein the stator is concentrically disposed around a rotor;
- forming a first recess in the main housing and the first extension housing at an interface between the main housing and the first extension housing;
- and
- placing a first insert in the first recess.
