s:With the study of soft starting system for differential gear train on large belt conveyor from the speed governing control point of view,it can be found that the controlling speed of the system is decided not only by the parameters of differential gear train but also by the power ratio and the ratio of pole num-bers of both motors.
本文介绍从调速控制的角度对大型带式输送机上的差动轮系软启动系统进行研究,发现该系统的控制速度不仅由差动轮系的参数决定,还由两电机的功率比和极数比决定。
补充资料：调频
载波的瞬时频率按调制信号的变化而变，但振幅不变的调制方式。载波经调频后成为调频波。用调频波传送信号可避免幅度干扰的影响而提高通信质量。广泛应用在通信、调频立体声广播和电视中。
