Abstract

Tubular-type linear generator for the free-piston engine is anlayzed using finite element method and its characteristics are explaind. Magnetic characteristics of the linear generator are calculated using the finite element method and various structures are considered to achieve the lowest detent force within the rated voltage. The path of the magnetic flux is constructed by the axially magnetized magnets and the iron pole, and the detent force is minimized by adjusting the width of the magnet pole.
