Segmented electric machine - modular motor and system topology for direct drives

摘要

Recent years have seen a growing need for large diameter direct drives, particularly in precision industry applications. Such drives are required to provide a variety of operating conditions and customers demand low-cost taylor-made drive solutions. Investigations into whether segmented direct drive motors may be used to satisfy market demands were performed. It was found that by using standardized motor modules, i.e. linear motor modules, excellent direct drive synchronous segment motors may be implemented.
