The focus of the work demonstrates the validation of the new shape translator taking account of leakage elements
in linear oscillating generator for a series hybrid electric vehicle. By comparison and analysis using the
various shapes of translator teeth, it is studied to minimization of the force ripple and increasing useful magnetic
flux by equivalent magnetic circuit (EMC) and finite element method (FEM). It will be analyzed considering
the leakage reluctances for a more practical and effective analysis, and design process of tubular linear
reluctance generator. At last, the trapezoidal shape of translator is selected as optimal model among the proposed
translator teeth in tubular linear reluctance generator. The results of this study will give elaborate information
about the design rules and the performance data of linear gensets.
