N2 - In this paper, a novel 5-phase double-sided C-core modular linear permanent-magnet synchronous machine (MLPMSM) used for the linear steering engine is researched. Firstly, the structure of the MLPMSM is depicted. Then the thrust produced by one module and the total thrust force of the machine are deduced and analyzed. In the ideal condition, all the harmonics in the thrust force can be eliminated except the 5qth (q= 1, 2, 3, 4,......) order harmonic, when 5 modules are arranged equidistantly. To suppress 5th order harmonic in thrust force, the opening of module's slot (Bs) is optimized. In addition, the first harmonic thrust ripple caused by the different flux distributions in end modules is researched and reduced by a proper current in the windings, located at the edge. The thrust ripple is greatly reduced by the adopted methods.
