Reducing Power Consumption of Powerful Grid Synchronous Motors

Abstract

Evolution the power electronics and microprocessor’s technology has contributed to that an adjustable electric drive based on synchronous and asynchronous motors has become predominant in metallurgical industry. However, a large number of nonadjustable powerful synchronous motors (SM) remain. With the existing technology of metallurgical industry, most powerful synchronous motors will remain in the near future and the issues of their effective use as energy-intensive consumers as energy-intensive consumers remain relevant and practically significant. The article discusses the unrealized reserves for power saving and the existing methods for starting powerful synchronous motors in rolling production, and also describes the developed model of a powerful grid synchronous motor.
