DC motor speed control circuit

Published:2011/3/23 3:32:00 Author:Jessie | Keyword: DC motor, speed control | From:SeekIC

This circuit can be used to control the rotating speed and direction of low power dc motors, series motorsor parallel motors. Motorsseries with rectifier bridge G1, then access them to the power transformer secondary windings n2. If rectifier bridge output terminal is impassability, motor stops, this is like potentiator's sliding contacts RP inmiddle position, if sliding contacts move upward or downward, then motor will rotate positive direction or reverse direction, so it can control the rotating of motor.
