[Abstract]:Aiming at the shortage of traditional submersible motor which needs to be equipped with reducer to drive submersible screw pump, a low speed submersible motor with double fractional slot concentrated windings is proposed to drive submersible screw pump. The motor stator adopts two sets of fractional slot concentrated windings with special space distance. According to the special winding structure, the magnetic potential of the motor at different times is analyzed, which shows that the motor can produce constant electromagnetic torque. The finite element method is used to analyze the two-dimensional transient field of the motor, and the magnetic field distribution and related characteristics of the motor under the condition of no-load and rated load are obtained. The results verify the rationality of the electromagnetic design of the motor. The designed motor can increase the number of poles without increasing the outer diameter of the stator of the motor, reduce the synchronous speed, and hopefully realize the submersible screw pump directly driven by the submersible motor, thus effectively reducing the cost of the whole oil recovery system. The pumping quality is greatly improved, which is of great significance to the energy saving of the whole system.
