Abstract :
This paper deals with characteristic analysis on ATMB. At first static characteristic analysis on ATMB was analyzed through not conventional EMC method but through EMC by considering fringing effect to improve its accuracy. And from magnetic force equation gained from static characteristic analysis equilibrium equation of force and voltage equation was deducted. Lastly, it was illustrated in state equation and by modeling PID controller dynamic characteristic analysis simulation was conducted.
