Analysis of U-I and U-U Type Rail and Actuator Used in Electromagnetic Levitation System Using FEM Software

Electromagnetic levitated and guided system is commonly used in the field of people transport, tool machines frictionless bearing and conveyor system. In the case of low speed people transport vehicles, the electromagnetic levitation offers the advantage of a very salient motion and of a reduced maintenance of the rail.In this work FEM based analysis and design of different structure of rail (guide-way) and electromagnetic levitation system (EMLS) has been performed utilizing ANSYS software. Actuator and guide-way are the most important part for magnetic levitation system. A FEM analysis utilizing ANSYS software has done to find out the flux pattern, working flux density, field intensity, force etc. for different single actuator based levitation system at different operating conditions. Different aspects of rail and actuator have been described based on the ANSYS simulation results. In this paper shows a simple magnetic model for the study of the levitation and guidance forces produced by an electromagnet and rail. The electromagnet shapes taken into consideration in this paper U type and with I and U type rail.
