| description | To address the heat dissipation problem of submersible motors, an improved strategy based on the characteristics of air gap fluid is proposed to avoid localized overheating of the motor to obtain better heat dissipation. Considering the heat exchange form of the submersible motor and the influence of multiple heat sources on the motor stator, a numerical calculation model of the temperature field inside the water-filled submersible motor is established. The temperature distribution of the stator of the submersible motor under different air gap inlet fluid flow rates is simulated based on the finite element analysis method. The simulation results show that the stator winding insulation realizes the necessary cooling. The reasonable axial flow rate of the motor air gap inlet fluid is 2 m/s. Finally, the validity of the method is verified by comparing the calculated results with the experimental data. The results of the study provide a theoretical basis for the determination of the reasonable flow rate of the air gap fluid and the optimization of the design of submersible motor drive pump wheel. |
