降压起动下异步电机起动参数的研究与分析

摘要

In the production life, induction motor occupies a large part, and it will produce great current in the startup momentary moment, so the reduced-voltage starting method is often used. Based on the theoretical analysis of the motor, in-depth analysis of the torque-speed characteristic curve is made, the startup time, startup power, startup consumption and other parameters in the startup momentary moment are studied, and a series of characteristic relationship when induction motor starting are obtained, which plays a guiding role in project practice.%在生产生活中，异步电机的使用占用很大一个部分，而异步电机在起动瞬间会产生较大的电流，所以，经常采用降压起动的方法。本文在电机理论分析的基础上，深入分析机械特性曲线，针对异步电机起动瞬间的时间、功率、损耗等参数进行研究，得出异步电机在起动时的一系列特性关系，对工程实践起到了一定的指导作用。
