Abstract:

The magnetic coupling can availably solve the leakiness problems of machine equips. But there is a problem currently in the common synchronous magnetic coupling that the inner rotor magnet steel is demagnetized under high temperature. According to reverse design method, a kind of novel permanent induction magnetic coupling is researched. Its inner rotor is similar to that of asynchronous motor, and it does not need permanent magnet material. So it can be used in both normal and high temperature and is free from transporting medium temperature. Because of the variety of magnetic field, it is extremely complicated. Here the software ANSYS FEM is used to analyze it. Its main process can be divided into three steps: solution preprocess, solution process and solution postprocessing, thus the magnetic field strength value of every point of the coupling can be gotten, and it can be shown conspicuously with the sketches or charts. Then the power and torque also can be solved accordingly.
