| Abstract: | The 3D mathematical model of the stator temperature field over the large submersible motor are developed based on heat transfer theory.The method of calculating the conductivity and thermal coefficient about submersible motor is given.The finite element method is used to calculate the 3D stator thermal field about submersible motor,and the rationality of the thermal field calculation method and the validity of the calculated values are verified by experimental results.The influence of different insulation in the motor stator temperature field are analysed,which could help optimum design of submersible motor in future applications. |
