摘要
对工作于轻载或空载下的感应电动机,适当调节定了端电压的幅值,可以实现效率最优。本文提出了一种以8031单片机为基础,以负载电流为控制量,使电机传动性能接近最优的方法。实验证明,当电机负载低于60％时,可取得一定的节能效果。
Maximin e(?)ciency can be realized (?) a in drction motor operating under lower load of ro(?) load by Properly adjusting the amplitude of stator terminal voltage.This papet proposes a single-board m icrocompater-based digital control system which ases the stator current of motor as control variable,end optimized drive performance can be obtained app(?)oxi mately.Experiments show that certain effect of saving power can be obtained ander the load lower than 60%.
