Abstract
The expediency of low-productivity oil wells continuous operation has been specified. The analysis of possible ways of transferring oil wells with low flow rate to continuous operation is given. We noted the most rational use of low-speed asynchronous electric motors in the electric drive of plunger pumps. The problems of low-speed asynchronous electric motors development and production have been considered. The emphasis is placed on high weight, size and cost parameters of low-speed asynchronous electric motors and low values of their efficiency and power factor. A number of possible solutions to these problems are proposed. Thus, it is recommended to use a stator winding with a shortened pole pitch length to improve the weight, size and cost parameters. Reduction of electrical and magnetic loads and the use of copper instead of aluminum as a stator and rotor windings material contribute to the increase of the efficiency factor. The use of internal compensation of magnetizing current and reactive power is aimed at achieving the power factor values close to one.
