Hello friends, I hope you all are doing great. Today, I am going to share the new DC Tachogenerator Library for Proteus V1.0 . Every speed-controlled machine needs to know how fast it really turns: the spindle of a lathe, the drum of a conveyor, the reel of a winder, the shaft of an old servo motor. For decades the answer was a tachogenerator - a small DC generator on the shaft whose output voltage is simply proportional to the speed. Read the volts, and you have the RPM.
