Abstract

The torque of magnetic coupling is sensitive to the number of magnetic poles, the magnetization profiles, the magnetic field strength of magnets, and the separation distance between the magnets of the coupling. For different multipole magnetic couplings with the same magnetic field strength, the torque of magnetic coupling is proportional to the number of magnetic poles at small separation distance, but it is inversely proportional to the number of magnetic poles as the separation distance becomes large. The theoretically calculated values of the torque of magnetic coupling are in excellent agreement with the experimentally measured values.
