FEA of Magnetic Field for Cylindrical Magnetic Coupling

In order to further study magnetic performance fo cylindrical magnetic coupling, the numerical simulaiton for magentic performance of cylindrical magnetic coupling was conducted with ANSYS software. The distribution law of the magnetic lines of force (B-lines) and the magnetic induction intensity under differetn magnetic poles and different magnetic rotation angles was studied. The numerical results show that the distribution of the magnectic lines of force (B-lines) and the magnetic induction intensity have obvious peridicity with the number of magnetic poles. The number of magnetic poles was bigger, the distribution of the magnetic lines of force (B-lines) and the magnetic induction intensity have obvious periodicity with the number of magnetic poles. The number of magnetic poles was biggen, the distribution of the magentic lines of force (B-lines) was more closely, its magnetic induction intensity was bigger, and ints magnetic performance was better. The numerical simulation and stufy was supposed to provide the useful reference for the design of cylindrical magnetic coupling.
