Calculation of a linear generator for a hybrid vehicle concept

Abstract

This publication deals with the design calculation of a linear generator intended for use in a hybrid power train design for a vehicle. The system surrounding the linear generator and some parameters have an influence on the linear generator. They will be explained to achieve a fundamental understanding of the requirements and the resulting topology selection. Then, the analytical and numerical calculations are presented. Furthermore, the question if the forces from a linear generator can be calculated either analytically or numerically will be discussed. From this, there results a presentation and analysis of the differences in the forces calculated. The calculated values are compared with the values measured on a prototype to permit an assessment of the quality of the calculations.
