关于三相异步电动机最大转矩与主要尺寸关系的研究

Study on the Relationship Between Maximum Torque and Main Dimensions of Three Phase Asynchronous Machine

本文作为研究大型异步电动机主要经济技术指标与成本关系的一个组成部分,从三相异步电动机的基本原理出发,详细研究了大型异步电动机的主要性能指标之一的最大转矩倍数(或称过载系数)与主要尺寸的关系.所得结论对设计及生产出低消耗及高性能的产品,提高企业和社会的经济效益有一定的指导意义.

This paper is a part of the researches on the relationship between the major econnomic and technical indexes and the cost of the large asynchronous machine.Based on the theory of the three-phase asynchronous machine,the relationship between per unit maximum torque(or overload factor)and main dimensions is completely studied. The conclusion is available for designing and producing asynehronous machine with low price and high performance to meet the market requirement and for increasing economic benefit of the enterprise.
