Design and Development of A Segmented Magnet Homopolar Torque Converter

Abstract

This program is for the research and development of a new mechanical power transmission concept: the segmented magnet homopolar torque converter. The purpose of this device is to convert unidirectional torque of constant speed (such as from a steam turbine prime mover) into variable speed output torque in either the forward or reverse directions. The concept offers an efficient, lightweight low volume design with potential application over a wide range of speeds and power ratings in the range from hundreds to tens of thousands of horsepower. This machine concept can be applied to commercial and military advanced concept vehicles for both terrain and marine environments. In Phase I the technical problems were reviewed, the machine concepts were studied, and a detailed technical plan was evolved for the entire program. In Phase II, a reliable constant speed current collection system was developed and demonstrated in an actual segmented magnet homopolar generator (SEGMAG). The objective of Phase III is to extend the technology developed in Phase II for constant speed machines to the case of the torque converter which must operate at variable and reversing speeds. The program places particular emphasis on the technology of advanced current collection systems for the reason this is essential for the success of the homopolar machine concept. Phases I, II, and the initial Phase III effort were based on the use of liquid metal current collectors. In Phase III-A (Begining July 1, 1975) work was redirected toward the use of a promising current collection concept utilizing a solid brush-gas-vapor additive system.
