【Abstract】 Magnetic drive is a new type of transmission technology without mechanical connection, which generates relative motion and transmits torque and power through the magnetic coupling between internal and external magnetic rotors.The size of a magnetic transmission mechanism for mud generator was designed by using Gauss theorem.The finite element model of the magnetic transmission mechanism was established by using ANSYS Maxwell.The distribution laws of its magnetic flux density and eddy current loss were analyzed, the influences of magnetic circuit structure and various permanent magnet parameters on transmission characteristics of the magnetic transmission mechanism were studied, and the causes of leading to the influences were analyzed.The magnetic transmission performance between internal and external magnetic rotors with different structural parameters was tested.The accuracy of Gauss theorem, finite element analysis is verified by comparison of theoretical, simulation and experiment results.The result shows that the error between Gauss theorem and finite element analysis result and experiment result is less than 12.6%.Therefore Gauss theorem and finite element analysis can be used as the design method of the magnetic transmission mechanism for mud generator.更多还原
