Rancangan Alat Pengontrol Kecepatan Putar Motor Listrik Berbasis Mikrokontroler AT89S52

Abstract

Had design a instrument who can measure and controlled of electric motor who active otomaticly. The Instrument controlled electric motor before with control voltage gived at motor. This instrument design for defend stability speed rotary motor although motor have interference by different load. All the part from this research instrument are stand of from optocoupler sensor, microcontroller and stepper motor. The instrument also have good carefulness in measuring with 0,83%. The weakness of the instrument is Instrument just can measure and control speed rotary adjust with input data, and have time response 1 second.
