Simulation of Reciprocal Power-fed Linear Induction Motor Drive Test

Based on the dynamic mathematical model of linear induction motor (LIM),a novel reciprocal power-fed linear drive experiment system was researched. The construction and operation principle of this scheme were discussed,and its high efficiency and flexibility were analyzed. The simulation model of the reciprocal power-fed LIM drive test rig was built including linear induction motors,inverters,controller and platform body with application of computer simulation. Simulation results is given to verify the validity of the proposed LIM drive test rig and this novel method offers a new thoughtway for designing and debugging actual reciprocal power-fed LIM drive test rig.
