摘要
本文阐述了利用倍频器和电网的周波补偿等手段组成的数字式测量系统,测量交流电动机的转差率和转速具有简单、便宜和高精度等优点。文中对转差率的瞬时动态测量也提出了简便的办法。该装置如配以适当的逻辑电路还可测量其他旋转体的转速。
This paper introduced that frequency multiplier and cycle compensating method of electric network are used to set up digital measuring system and to measure A.C. motor slip and rotational speed. It has a lot of advantages such as simplicity, Convenience and high accuracy. In this paper it is also proposed as the simple and reliable way to measure slip of instantaneous dynamic.If some necessary logic circuits were added, it can be used to measure Other rotational speeds.
