A novel tangential radial hybrid excitation synchronous variable frequency aircraft generator

This paper introduces a novel tangential radial hybrid excitation synchronous generator (or T/R-HESG, for short). Firstly, the author deeply analyses its magnetic path model, completes the design and gives some improved methods with the assistance of Ansoft Maxwell 14 software. Then the author developed two models of T/R-HESG, but only one, a 380V/1.5KVA prototype, has been fabricated and its corresponding control strategies are studied in the different load experiment with working frequency of 50Hz. However, the other one, serving as a variable frequency aircraft generator, is manufacturing, whose simulation results are given in this article. Experimental results and simulation results both indicate that T/R-HESG has advantages of high power density and convenience of voltage-regulating. This kind of machine is very likely to play as a novel aircraft generator.
