ABSTRACT:
An electric submersible pump having an electric motor forming a unit with the pump impeller and where the stator of the motor has 2 pm (p = number of pole pairs, m = number of phases) groups of coils, each group being subdivided into a plurality of coils of different width arranged symmetrically with respect to the axis of each group of coils and where the coils of each group are adapted to have different voltages applied thereto. The voltages imparted to the coils increase from the coil of smallest width to the coil of largest width by small amounts to eliminate arcing between adjacent conductors in the medium being conveyed. A portion of the liquid pumped by the impeller moves past the coils to provide cooling.
The method of operating an asynchronous motor having a plurality of coils in the stator where each coil had a single turn winding comprising the steps of applying different voltages to the coils where the voltages between adjacent coils is less than that to cause arcing between adjacent coils.
