diy mosfet motor controller
This is convenient for many projects using micro control motorscontroller.
Can be used as an electronic speed controller (ESC)
With forward and reverse controls.
It can be used for robots, remote control projects, portable vehicles and most things that are motorized.
It also uses very few parts.
All of this is made into a small package to fit your DIY project.
This circuit is based on driving a larger load circuit in my book.
The circuit uses only one MOSFET and one diode.
It means a micro.
The controller that controls the speed of the motor.
To be able to run in reverse, I just added a DPDT relay and another MOSFET, diode pair to control the polarity switch.
I hope you enjoyed the instructions.
This motor drive is simple.
Because of its simplicity, it uses only a few parts.
Material: Tools: Place all parts on the perfboard.
Place them so you can easily weld the circuit to the schematic shown above and still fit neatly on the board.
For pin straps, just break 2 pin increments and 4 pin increments (
If you want to weld the motor directly to the circuit, you don\'t have to do 2 pin increments).
Cut short 2-pin increments on both sides and use your wire stripping pliers to bend the long ends of the 4-pin increments at a 90-degree angle.
If you don\'t have this feature for your strip pliers, just use an extra set of pliers.
After placing all the components on the perfboard.
Weld the circuit to the schematic shown above.
You can use any soldering iron and soldering tin you like.
Connect two closed leads and jumpers using part leads to connect the remote leads.
For jumpers, cut and peel off the end of a small piece of wire using your stripping machine.
Weld two distant leads with them.
For the perfboard, I found that the perfboard of copper is best suited for soldering this compact circuit, but the bare perfboard is cheaper.
In this step, you can also weld the motor channel to the circuit board as I did, or use a 2-pin increment.
The circuit I completed is shown above.
For you to use it in a small system, a controller or a robot, the next thing to do is cut off the circuit.
I cut to the size of the circuit I made, but you can cut to whatever size you want, or different functions.
Just make sure the circuit works.
Cut the perfboard from the bottom so that you can cut under the control pin and the Power pin.
Cut it out using DREMEL or any small saw.
I found DREMEL to be the easiest tool to cut a perfboard, but use any method you would like to do the job.
Finally, make sure that the control pins and power pins can be plugged into the board or other circuits.
Now just add the finishing touches and organize.
Shorten the remaining wires that stretch out.
Use the stripping machine to cut off the protruding wires.
You can also use the pliers end of the stripping pliers to bend the wire back and forth until the wire is disconnected.
Make sure that no solder joints are damaged using this method.
After the plug of the hot glue gun.
To ensure that the circuit is not short-circuited, use a hot glue gun with a saw-shaped pattern to cover the circuit.
The finished product should look like the picture above.
This should then prevent the circuit from being short-circuited and further insulating and protecting the circuit.
It\'s time to use the new motor controller.
It should be easier if you design and build it like I did, and you can follow the layout above.
If you put your parts in a different place, or weld the circuit together is different from just looking at the schematic layout above.
Either way, make sure you see the schematic diagram above.
