摘要：

The tubular linear oscillating machine can achieve reciprocating movement directly without auxiliary transmission mechanisms, which is widely used in the free-piston energy conversion system. To achieve a lower thrust ripple and eliminate the eddy current effect, a circumferential silicon steel stack is usually utilized in the stator, however, it results in assembling difficulties. In this article, a radially split lamination tubular linear permanent magnet oscillating machine with auxiliary configuration (RSL-TLPMOMA) is proposed to solve the problem. First, the laminated coefficient expression of split-laminated is deduced, the influence of laminated number and radius ratio on laminated coefficient is discussed, and the optimal combination of the laminated number under different radius ratios is given. Second, the subdomain (SD) method is used to analyze RSL-TLPMOMA, the auxiliary teeth, slot, and end effect are considered. Finally, a prototype is manufactured and tested.
