Abstract Synchronous magnetic couplings have been widely used in chemical industry, pharmacy and etc. If the working temperature is high, a synchronous magnetic coupling may not operate in normal state because of the demagnetization of magnets on its internal rotor. This problem has been a trouble for a long time. A new type magnetic coupling which works according to the operating principles of squirrel cage asynchronous motors can solve this problem effectively. Finite element method is used to determine the magnetic field distribution of this new type magnetic coupling. The calculated results of torque and the difference between the rotation speeds of internal rotor and external rotor are compared with the experimental results. The experimental results indicate that this design is practicable.
