Study on the development of the surface magnet type magnetic gear

Magnetic gears are a force transmitter consisting of permanent magnets. The transmission torque properties have been improved by using the rare earth magnets and the computer aided design techniques. However, in the analysis and experimental results is that there is a big difference has been reported. As one of the causes, in the analysis is considered that the actual movement of the magnetic gear has not been reproduced. Therefore, we have tried to do a detailed analysis of movement by calculating the torque from the results of magnetic field analysis. By solving the equations of motion from the torque applied to the secondary rotor, to calculate the position of the secondary rotor of next step, do the analysis in line with the actual movement of the magnetic gear.
