FIELD: oil industry.SUBSTANCE: invention relates to oil industry and can be used to create drive of a submersible electric pump to lift fluid from an oil well. Submersible electric motor comprises a housing, stator, rotor, input lead and module with a cosine capacitor. Electric connector of the cosine capacitor is placed in the lower part of the module. Isolated power conductor is arranged in the stator slots and is connected to the electrical connector of the cosine capacitor and the current lead of the submersible electric motor. Inner space of the cosine capacitor is isolated from the oil, and the inner space of the submersible motor, filled with oil, is interconnected with the space around the module. Sleeve of the base of the submersible motor can be used as a module in the submersible electric motor.EFFECT: technical result consists in the cooling of the cosine capacitor and improvement of the reliability of the current lead.1 cl, 2 dwg |
