Abstract
A submersed electric motor includes a stator assembly arranged within an annular insulation chamber, and a stator with stator windings and a capacitive electric starter which is connected electrically thereto. The insulation chamber is formed between an outer tubular jacket, an inner tubular jacket, which is coaxial to the outer tubular jacket, with two annular end covers adapted to close the annular interspace between the outer jacket and the inner jacket. The submersed electric motor further includes a rotor arranged inside the inner tubular jacket. The capacitive electric starter includes at least two capacitors, which are mutually complementary, and have a transverse cross-section with an arc-like profile and are connected in parallel to each other.
