Dynamic simulation of planetary type magnetic gear based on reluctance network analysis

Magnetic gears have attractive features such as low acoustic noise and maintenance-free operation in comparison with conventional mechanical gears. Planetary type magnetic gears, especially, have higher transmission torque than the other types. Therefore, the magnetic gears are expected to be put into practical use. This paper presents a method for dynamic simulation of the planetary type magnetic gears based on reluctance network analysis (RNA). The RNA has several features including a simple analytical model, high calculation accuracy, and ease of coupled simulation with rotational motion of rotors.
