Design and Temperature Field Analysis of Submersible Motor

Beam-type oil production system has been difficult to adapt to complex well conditions in the middle and late stages of oilfield exploitation. It is of great significance to research and develop submersible motors with low speed, large torque, high efficiency and energy saving. According to the structural characteristics of submersible motor, this paper presents the overall structural scheme of motor. A 3D steady-state temperature field model of the motor is established. Through the analysis of the influence of the surface heat transfer coefficient and insulation material on the temperature change of the motor, the heat dissipation of the motor is mastered.
