5A DC PWM Motor Speed Controller – Assembled – CANUK1102
This fully assembled 5A DC PWM motor speed controller used the popular 555 Timer Integrated Circuit to generate a Pulse-Width-Modulated (PWM) output voltage with adjustable duty cycle in order to control the speed of a DC motor without sacrificing torque. The motor speed controller incorporates a high power MOSFET with a heat sink and can easily provide a continuous current of 5A to your DC motor or other DC load. The circuit also includes an LED whose brightness varies proportional to the relative speed of the motor therefore giving a visual feedback of the current speed.
The PWM frequency is approximately 140 Hz with the Duty Cycle adjustable from approximately 1% to 99%. The supply voltage can be between 6 to a maximum of 16V.
This electronic circuit is also available as a solder kit – please see our part number CANCK1102
