Abstract

A high-speed, small volume, light weight, high efficiency and power density generator for the miniature turbojet system has been gradually investigated. This paper focuses on the design of a 500W, 100000rpm generator suitable for use with the turbojet system. The design procedure selects the suitable machine type, at the same time, the rotor structure, the design of stator and windings are discussed in details. Through the finite element analysis and electromagnetic simulation, the distribution of the generator´s magnetic field and relative performances are obtained. At last, a permanent-magnet machine with a volume of 31cm³ is manufactured to do the experiment.
