浅谈异步电机变频调速

文章主要介绍了交流异步电机的发展及变频调速的基本原理。变频调速可以构成高动态性能的交流调速系统来取代直流调速系统,是交流调速的主要发展方向。与其他交流电机调速方式对比,变频调速具有平滑软启动、降低启动冲击电流、减少变压器占有量、确保电机安全、适用于要求精度高、调速性能较好场合等优点。

On the induction motor speed regulation

This paper mainly introduces the development of acinduction motor and the fundamental principle of variable frequency con-trol.Variable frequency speed regulation can form high dynamic performance of communication speed regulation system to replace dc speed control system,is the main direction ofac speed adjustment.And other ac motor speed adjustment waycontrast,variable frequen-cy speed advantage:smooth soft start,reduce the impulse current transformer,reduce the start,ensure safety,occupancy of motor used in high precision requirements,the performance of speed is good occasion.
