기중기의 모터속도 측정장치 개발
Development of the speed-measurement device of motor in a crane
초록
The conventional motor in a crane has a tan generator to feed back the number of turns. The tan generator is contacted to a motor shaft through the coupling. Don has been often generated because the coupling has worn out while the motor is turning. In this paper, we design the speed-measurement device of motor in a un. The device is composed of PIC16F84 controller, photo-sensor, and analog-to digital converter. The photo sensor measures the turn of a motor without contact so the device decreases the probability of errors. And The device can acknowledge the turn direction of the motor with a gin81e senor and two color reflectors.
