Abstract:
The air-gap flux density formula and thrust expression of long primary double sided linear induction machine (DLIM) in the secondary motion reference frame are deduced by using the Maxwell equations firstly. Then, by analyzing the factors that affect the thrust ripple in the thrust expression, a shuttle type secondary structure of long primary DLIMs is proposed, and its thrust performances of the machine with different shuttle size combinations are simulated and compared with that of plate secondary long primary DLIM. Comparison results show that the new secondary structure can suppress the thrust ripple and improve the stability of system acceleration.
