Switched reluctance motors

摘要

Motor design engineers have long been searching for a solution to their drive application problems which is low cost, reliable, versatile in application, fault tolerant and quiet. The motor design which was most likely to achieve that coveted position for several years was the switched reluctance motor (SRM). However, designers found difficulty in making this type of motor quiet enough for some applications, particularly those in residential environments. Breakthroughs in noise control at Emerson and its subsidiary companies over the last two years have made that no longer an issue. Thus the SRM is now poised to win a new and powerful place in motor drive applications. The author describes the constructional features of switched reluctance motors and their manufacture.
