| الوصف: | Aiming to improve the efficiency of the water-filled submersible motor, the method of optimizing the ratio of diameter to shaft length and air-gap length of the motor is proposed to reduce the water friction loss of the water-filled submersible motor. By analyzing the composition of the mechanical loss and the research status of the water friction loss of the water-filled submersible motor, the optimization methods of the water-filled submersible motor efficiency are determined. Two-dimensional time-harmonic field solutions are employed in this paper to accurately estimate the electromagnetic performance of the submersible motor, which costs less time and computational resources compared to the transient solution. By fitting the curves of water friction loss and electromagnetic losses with the optimized parameters, the influence of the ratio of diameter to shaft length and the length of the air-gap on the efficiency of the motor is analyzed. Finally, the parameters of the motor are determined, with the consideration of the influence of the radial to axial ratio and the air-gap length on the performance parameters of the motor and the requirements of actual working conditions. The results show that the two methods can effectively reduce the water friction loss of the water-filled submersible motor and improve the efficiency of the water-filled submersible motor in the motor design stage. |
