Coupling Characteristics Research On Electromagnetism And Temperature And Force Of Magnetic Isolated Segment In Submersible Motor

Contrary to the physics field coupling problem of submersible motor.Influence law of magnetic isolated segment and rotor bearing size on eddy loss,temperature distribution and force is discussed by studying the influence ofelectromagnetic properties, heat transfer law, force distribution of magneticisolated segment and rotor bearing and exploring the coupling characteristicsamong these types of physical fields. Conduct the simulation analysis byestablishing a coupling model of Force-Electric-Thermal of magnetic isolatedsegment and rotor bearing. Obtain the coupling influence of these physical fields.Research the mechanical properties, electrical conductivity and thermalconductivity properties of different metals or alloys. Reduce additional losses,temperature,while improving the ability to multi-point support of segmentationby using the non-magnetic material or alloy material for the manufacture of rotorbearing.Whether can improve the stability of submersible motors by calculate and analyze the model. Explore the influence law of magnetic isolated segment androtor bearing size on eddy loss, heat transfer and temperature distribution under the condition of stress constraints.Draw correlation curve to provide theoretical support for the future motor design.Design electromagnetic and temperature experiments for submersible motors.Simulate submersible motor stable operation under actual working conditionsby designing two prototypes.test the parameters of the motor,and compared with the simulation results. Together with the method of experimental contrast provedthe accuracy of the calculation method and result to become the theoretical basisfor studying other high-performance submersible motors.
