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

Abstract

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.

The role of magnetic field in the biopharmaceutical production: Current perspectives

“…We observed that most of the experimental setup in the reviewed articles was developed in such way that cells were placed for exposure right next to, right under or in between the MF generator, which would never be true for humans and the electrical appliances. This is also verified by the physics that by increasing the distance, the MF reduces [ 29 ] and, therefore, the induced effect reduces or vanishes.…”

“…The strength of MF within the air gap induced by magnetic couplings depends on a number of factors, including the materials used, the shape, width and height of permanent magnets, the number of pole pairs, the axial length and the air gap [ 27 ]. The smaller is the air gap, the higher magnetic flux density and vice versa [ [27] , [28] , [29] ].…”

Calculation and Analysis of Drive Torque of Axial Magnetic Drive Mechanism

“…When the active rotor was stopped, the passive rotor synchronization stopped. Namely, it was the axial magnetic coupling principle [4].…”
