The Steady State Analysis and Performance of an Experimental Autodyne

Some ten years ago Professor Otto Benedikt published a book entitled ´The Autodyne, a New Electrical Machine´. About the same time, however, machines engineers in the West were concentrating their efforts towards invertor fed machines using semiconductor devices, and because of this, interest in the potential of the autodyne has been negligable. This paper presents the theory and steady state analysis of the autodyne in familiar form, and gives the results obtained from a prototype machine, which was built up from an existing rotary convertor.
