The rotary converter

Abstract

Introduction: The rotary converter as a practical element in the transmission of power is a machine of comparatively recent date. Among the first practical converters noted was one exhibited at the Frankfort Exposition of 1891. This machine was of the flat ring, Schuckert make, fitted with four collecting rings outside of the bearing at the commutator end. This machine was operated successfully in its manifold and diverse functions. The rapid growth of the converter and its extension into a large field of usefulness has taken place during the past eight years. A brief comparison of its growth will be mentioned later in this discussion.
