The primary of linear induction motor which drives the metro is installed on the chassis bogie, and because it is quite strict with laying down railway rail to use flat linear induction motor to drive metro, its secondary - - - - reaction board ( called induction board ), which is a kind of compound board of aluminum and steel, is fixed on the rail sleeper between the track. it is the airgap which is a gap between the primary and secondary of lim. the electromagnetic airgap is a very important parameter of lim
