Research on the Analysis Method of Magnetic Field in the Axial Magnetic Drive Mechanism

The numerical analysis and calculation of magnetic field is one of the key issues for designing the magnetic drive mechanisms. This paper discusses the method of finite element analysis of the magnetic field based on ANSYS software, analyzes and simulates the magnetic field in the axial magnetic drive mechanism of the latest textile twisting spindles by means of ANSYS, analyzes and calculates the magnetic induction intensity, magnetic field intensity distribution with the different thickness of the air gap between the drive rotor and driven rotor, and the different quantity of magnets. The analysis method and results can provide reference for the design of magnetic drive mechanisms.
