Easy DC Motor Controller
Very good circuit. It works great
Very good circuit! driving a DC motor with Mosfets. I simulated your circuit with proteus and works great, I builded it up and works pretty good.
Can you please tell me how i connect my arduino or motors to this type of motor driver .
I am curious how you turn on the high side N-MOSFETS in your circuit. To turn these on the gate voltage would need to be significantly higher than the source. In other words, you would need a separate voltage source which supplies the voltage to charge the high side gates. I am unsure why your schematic would even work as the high side MOSFET source is close to 12V already.
Hi,thank you for this great project. I want to control the speed of the motor using pwm with Arduino. How can I do that using this circuit ?
Can you add a simple circuit to run this dc controller with only 1 pmw input which is similar circuit to a L293D driver? I have a Kyosho 370 dc motor.
Hey nice work, but i will ask why did you use NPN and PNP transistors back to back? Cant you connect NPN transistors directly to N-Mosfets, it will work aswell?
Hi dude...I m giving power supply of 12 volts but only getting about 8 volts at motor o/p...this voltage would give low rpm nd low power to motors.pls help me i want full 12 volts output @ output.i hav used bc557 and bc 547 transistors and corrected the emitter collector of Q5 ND Q6 as stated by u but then also m getting only 8 volts which is not sufficient to run the motors..pls reply ASAP...-Thnks in advance... :-) - ManishVarma
I am designing a thermostat circuit using 741 op amp as a comparator, 555 timer as adjustable pulse with controlled DC and a MOSFET fire the dc motor control. Would your application work with this? - kbrumleve
Sure, as long as you credit me and link here! What's your website? :)
great projectcan i place your project on my website.i'm working on a website which is related to electrical projects.i also mention your name, link and other info.plz reply
If you drive a motor that draws a lot of current they might need heatsinks. I didn't need any with the little motor I used to demonstrate it though.
Also can I use 3904 and 3906 transistors?
Do the Mosfets need a heat sink
Yes this circuit seems to work exceptionally well, A PCB version would be preferable for durability and professionality. Maybe a variety of circuits with different power handling capabilities. Like a little pack you get with the PCB and the components and you solder them on yourself? I would like to thank you for this circuit as I was able to adapt it further to create a robot arm controller and control 5 motors with this one circuit.
