DC move hasten control employ Microprocessor technique Intoduction : This is the oppose diagram utilise in the project! hither the DC labor is controlled by the microprocessor (8085). The kit theatrical roled was dynalog 8085 kit. The DC motor is genuinely difficult to control unlike the stepper motor, which butt be controlled by giving the appropriate control WORD. By disherning the DC motor theory we know the diametric methods used to control the motor, the most primitive and the formerly upon a time the most popularly method was WARDLEONARD motor festinate control, but this had many disadvantage, so the world of Electronics brought in the thyristor control, which were very flexible and stinkpot be employed to use AC instead of DC cause they had a intact convertor. The thyristor-based dodge is good but when used with Microprocessor based secureness control they are really good. We have shown the block diagram, locomote diagram used by us to control a low ly tape recorder sized motor velocity CONTROL:. The microprocessor takes a feedback from the CONTACTLESS INFRARED direct SPEED measurement intentional and developed by us. It is similar to a carrousel encoder we used only one wooden rigid disc with a hole (even at center for mounting purpose).

indeed using a sensor (Infrared) like those readily easy in the market (we have shown it in diagram) or a leafy vegetable infra LED pair mount and aligned decent to sense each other. When the DISC short-circuit the counter starts tally but it increment only when the LED come in sight of each other which is contingent when the hole good deal of the disc comes in bankroll over we can! find the speed of the rotation by proper calibration .The main lying-in of counting, calibrating, calculating, compare is incorporated in the software used the 8085 dust (EPROM).So by comparing the speed reading with the w anted/ mold speed we can adjust the threshold controlling the DC motor effect come forth and hence in turn control the DC motor. Safety:Its important to attach the power supply region,...If you want to get a generous essay, order it on our website: BestEssayCheap.com
