Do you want to build it? US $3.73-$4.78 / Piece 2 Pieces (Min. This circuit is suitable for the DC motor with a power that is not much. Today I share with you a motor control circuit new small project. How to Run a 24 Volt DC Motor on 12 Volts. Not all 4 wire motors are Armature Voltage controlled. The choice of Q2 must correspond to the current of the motor as well. So, you can build it on a universal PCB. The 12V DC PWM controller features a 5 inches(12.7 cm) long connection to its potentiometer. And, both diodes D3 and D4 determine the direction of charge and discharge current of C2. While motor function, maybe a reverse current, it must put Diode D1-1N4148 to prevent this circuit. These motors are capable of speed modulation when required. But if you want easy and cheap.
