Analysis of Water Friction Loss and Calculation of Rotor 3D Temperature Field for Wet Submersible Motor

Abstract

The water friction which is produced in the high-voltage wet submersible motor is much more than that of General motor, and it plays an important role in total consumption of motor. It is difficult to calculate the consumption of water friction. In order to study the high-voltage wet submersible motor water friction loss and temperature field distribution more accurately, this paper take the 6kV-3150kW motor as an example. Based on the Fluid Theory and the Heat Transfer Theory, it establishes the model of the loss of water friction and rotor temperature field. At last, the finite element software is used to analyze the water friction loss of motor and calculate the rotor temperature field .The rationality of the model and the validity of the calculated value are verified by the experimental results, which lay a theoretical foundation for the optimum design of high-voltage wet submersible motor for future application.
