摘要
基于异步电动机电磁转矩的实用表达式,分析了电动机分别带恒转矩、恒功率和平方律性质的三类典型负载的降压运行,得出其转差率和转速降落的计算方法,并进行了实例计算研究.在理论上为校核降压引起的电动机转速降低是否满足运行要求提供了依据.
Based on the practical expression of the electromagnetic torque of asynchronous motor, this paper analyzed the reducing voltage operation when motor run with three typical load such as constant torque, constant power and square law nature respectively. It can draw a conclusion about the calculation method of slip and speed landing, and carried out example calculation and study, which provides the theory basis for motor speed decreased whether it meet operation requirements caused by verifying reducing voltage.
