Numerical Analysis of Electromagnetic Field of Solid Rotor Asynchronous Permanent Magnetic Coupling by Finite Element Method
A new-type of solid inner rotor asynchronous magnetic couplings which work on the principle of electromagnetic induction is researched by ourselves. This kind of asynchronous magnetic couplings can solve the problem effectively that the permanent magnets on its inner rotor is demagnetized if its temperature is high, because its inner rotor need not the permanent magnets, In order to study the transmission capability of the new-type magnetic couplings, its magnetic field need to be analyzed. Because of its magnetic field variety, it is extremely complicated and a precision result is difficult to get by the analytic method of the magnetic field calculation. Here the software ANSYS FEM is used to analyze its magnetic field. And some formulas were deduced and used to calculate its torque. The experimental and calculational results indicate that this design is practicable.
