Temperature Field Analysis of Linear Motor Considering New Energy Generation Access and Fluid-Solid Coupling Boundary

In order to solve the problem that the fluid-solid boundary heat dissipation coefficient of the submersible linear motor is difficult to deal with, this paper takes the submersible linear motor as the object and uses the fluid-solid coupling boundary condition to solve the three-dimensional steady-state temperature field of the motor in combination with the actual working conditions. On this basis, considering the special structure of the submersible linear motor and the characteristics of new energy access, the overall three-dimensional model including the motor stator, rotor, oil guide pipe, one-way valve, casing and flowing crude oil, and the photovoltaic energy storage output model are established; the temperature distribution of the motor under different conditions is studied, and the cloud map of the overall temperature distribution of the motor is obtained. The influence of different conditions and photovoltaic and energy storage output characteristics on the submersible linear motor is then analyzed. Finally, the rationality and feasibility of the fluid-solid coupling model and the new energy access characteristics are verified through the simulation.
