The expediency of conducting research in the direction of improving the energy efficiency of submersible induction motors due to the introduction of a set of tools for the design synthesis of their innovative designs was reasoned. Means of design synthesis of submersible induction motors of innovative designs are considered. The combination of which in the implementation of the design will allow to increase the level of improvement of submersible induction motors in accordance with the requirements for modern equipment, such as: reliability, energy efficiency, economy. The results of realization of the induction motor optimal design synthesis of the submersible pump of an innovative design on the basis of the ПЭДВ 2.8-140 motor by criterion of a maximum efficiency are resulted.
