摘要: 设计制作一个脉宽调速器,使其工作频率和占空比均可调节,频率调节范围3-5KHZ, 占空比调节范围为30-70%,,根据其参数设计出功率放大器,使之推动直流电动机工作,并用4位数码管显示出电动机每秒所转的圈数, 以监视电动机的调速情况.
关键词: 转速检测脉宽调速功率放大器数码管显示
Summary: The design manufactures a vein breadth adjusts soon machine, make its work frequency with occupy empty ratio all adjustable stanza, the frequency regulates scope 3-5 KHZ, occupy empty ratio regulate scope as 30-70%, choose to settle electric voltage as with the sum a sum settles electric current as a number for of small direct current electrical engineering, according to its parameter designing power enlarger, the push direct current motive that make working, counteracting 4 figureses taking care of displaying electric motor each turning, toing keep watch on the electric motor adjusts soon circumstance.
Key phrase: Turn to examine soon the vein
