Research on Electromagnetic Field Analysis of Magnetic Levitation Rail Machine
This paper introduced the working principle of magnetic levitation rail machine and carried out the magnetic analysis. Take the weight of 132N simulation workbench prototype for example, finite element analysis of rail electromagnetic fields is applied through ANSYS software to find out the variation law of magnetic field distribution and affecting factors. Analysis shows that magnetic levitation rail machine has small leakage magnetic field, high load capacity and large anti-external disturbances capacity if the parallelism and the straightness of magnetic levitation rail machine are no more than 0.1mm and 0.2mm respectively when the table is suspended normally. The research results provides theoretical basis for structural optimization of the magnetic levitation rail machine.
