Abstract
Motors for use in downhole systems such as electric submersible pumps. In one embodiment, an ESP system includes a pump and a motor which drives the pump. The motor has an elongated cylindrical stator and a rotor which is concentrically positioned within a bore through the stator. The rotor is driven by the stator to rotate within the bore. The stator comprises a plurality of separable, interconnected modular stator sections which may be identical. Between each pair of adjacent stator sections, a corresponding interconnect electrically connects coils of magnet wire in the stator sections to a power source. In some cases, the interconnect between stator sections electrically connects the coils of magnet wire serially in the adjacent stator sections. In other embodiments, the coils in adjacent stator sections are connected in parallel the power source.
