Switched reluctance motor systems poised for rapid growth
The emergence of a rugged, versatile, and highly efficient alternative to conventional electric motors promises to have a major impact on drivepower markets over the next decade. Although switched reluctance drives are not yet available ``off the shelf`` from major motor manufacturers, they are likely to compete favorably across a broad range of applications, due to their superior performance characteristics. Switched reluctance drives maintain higher torque and efficiency over broader speed ranges than can be achieved with other advanced variable-speed systems, can be programmed to precisely match the loads they serve and, in high-volume production, are likely to be less expensive than competing systems. The principal obstacle to rapid commercialization of switched reluctance motors is the fact that few engineers are trained to perform the exacting and specialized design that this technology requires. This hurdle is gradually being overcome as over two dozen firms now design or manufacture switched reluctance drives, and several are moving into mass production applications. As these and other firms gain experience with the technology, new opportunities will arise for utilities, energy users, and original equipment manufacturers to capture the benefits of switched reluctance motor systems. This report appraises recent progress toward moving switched reluctance drives to mass production and provides an inventory of major manufacturers.
