In the current technological developments, DC motors are widely used in areas and many electronic devices. To regulate the speed of a DC motor, it can be done in a conventional way. Operating a DC motor by setting the armature voltage and controlling the field voltage / current (excitation) using an auto-transformer or starting resistance, requires regular and complicated maintenance. The equipment is physically impractical, relatively expensive, and the armature voltage regulation has low efficiency. Therefore it will be required to control the DC motor speed more practical and economic. To get the solution , the authors compile a final project entitled "Perancangan Penyearah Terkendali untuk Pengaturan Kecepatan Motor DC". As a follow-up of this final project, the authors designed a controlled rectifier kit that converts AC voltage into controlled DC voltage, which can also be used for the lab class to be the introduction and utilization of SCR (Silicon Controlled Rectifier) operation. In this reseach, a DC motor speed control kit was designed with a 220V AC source that was reduced to 12V using a 1A CT transformer. The output from the transformer is connected to the ground, and to the anode of the SCR (BT151) and also to the gate SCR (which was previously rectified using the IN4004 diode and coupled with a 1K potentiometer). The output of the SCR cathode is DC voltage can be adjusted with a potentiometer where when the potentiometer is set from 0% to 100% it can directly change the firing angle which affects the output voltage. Therefore the output voltage connected to the DC motor control can regulate the motor speed. From this research, it has been confirmed that at 25% potentiometer setting, with firing angle at 30o the motor cannot rotate . And at 100% potentiometer setting, with firing angle at 180o the motor can rotate at a speed of ≤ 1867 rpm. The voltage trigger is inversely proportional to the firing angle at the output of the SCR. The greater trigger voltage, then smaller the angle of the waves and the slower rotation of the motor
