This paper presents calculation and finite element analysis of a high-performance permanent magnetic gear. Magnetic gears can offer significant potential advantages compared with mechanical gears,such as reduced maintenance and improved reliability,inherent overload protection,and physical isolation between the input and output shafts.Based on the practical application,this paper mainly describes the theory and structure of the magnetic gears.And in this paper,we set up the physical and mathematic model for finite element analysis of the magnetic gear.After the finite element analysis of the magnetic gear,we simulate the distribution of the magnetic field. By comparing the calculation data with the data of finite element analysis software ,we conclude that the finite element analysis of the magntic gear is corect.
