Inside Motor Controller 60V 20A | Copy Diagram
-Parameters: motor speed controller input voltage range is 9-60V, output current range is 0-20A, continuous power is 1200W.
-Application: the dc motor driver can be used to brush motor speed regulation, light dimming regulation in the DC circuit.Note: The motor cannot be used in electric vehicles.
-Speed Control: our motor control board can regulate motor speed by potentiometer; what's more, it support clockwise/anticlock-wise rotation adjustment.
-Easy Wiring: thick red wire for the positive of the power supply, and thick balck for the negative; thick blue wire for the motor positive, and the thick green for the motor negative.
-PWM: the advantage of using a pulse width modulation (PWM) method for dimming / speed regulation is that the energy of the power supply can be fully utilized and the circuit is highly efficient.
Today I bought a cheap motor controller, it is rated 60V / 20A. It uses an NE555 IC, Use the LM317 IC to reduce the voltage to 8V for NE555. A 30A diode to protect the mosfet. A 100K potentiometer to adjust the pulse width (PWM). With 2 mosfet 80N70, I think, it will work fine at 20A.

All my projects are free, I design them on EAGLE 6.0. I uploaded it to Google drive. You need to use a web browser to download the file and open the file with winrar software (extract) on the PC. Open schematic file (.SCH) and PCB file (.BRD) with EAGLE software.
Hope you enjoy my videos and projects. Like, share and don't forget to subscribe to my channel. one more thing, thanks to everyone, my channel has reached 50K subscribers.
