With advantages of strong drive capability,nested-loop secondary linear machine(NLS-LM)has great potentiality in linear *** its secondary structure with multiple loops,it is difficult to calculate the electromagnetic thrust of NLS-LM ***,in this paper,one thrust calculation method is proposed considering variable loop inductance and transient loop ***,to establish the secondary winding function,the modeling domain is confined to a limited range,and the equivalent loop span is employed by analyzing the coupling relationship between primary and ***,in order to obtain the secondary flux density,the transient secondary current is solved based on the loop impedance and induced ***,the electromagnetic thrust can be calculated reasonably by the given primary current sheet and the calculated secondary flux *** simulations and experiments have demonstrated the effectiveness of the proposed method.
