- In this video, you will see that we can make a DC motor speed controller with two simple parts.
The circuit of this project is very simple and consists of two parts:
- IRFZ44N MOSFET
- 10 kOhm potentiometer
Important note: To use a 12 volt motor, set the input to 12 volts and to use a 6 volt motor, set the input to 6 volts.
If you have new ideas for future videos, leave them in the comments.

✅️Note: To prevent damage to the MOSFET from back EMF, connect a flyback diode with the motor.
Thank you for your support, I am waiting for your comments and suggestions. ❤
Salamat idol may natutunan ako
Hi dear friend! I am very glad that it was useful to you. have a nice day. 🌺🙏
This is toturial what i find for...simple and easy to understand for me and its work.allready test it..Thank Bro..keep it up to many good idea..
Thank you dear friend, I am glad that it helped you 🌺
استمر بنشر ياصديقي 👏👏👏👏👏
شكرا لدعمكم 😉🌺
أحسنت 👍👍👍👍
شكرا لتعليقك يا صديقي العزيز 🌺🌺
if the source voltage drops down, e.g. on a 12vot, you have set it to 6volt, when the source becomes 10volt, will the output drop too?
When the input voltage is 12 V, the output value varies between 0 and 12 volts.
When the input voltage is 10 V, the output value varies between 0 and 10 volts, which can be increased or decreased by turning the potentiometer.
To the top , well done 🎉
Thanks for your comment ❤️
Working tnx alot
Thank you dear friend.
I'm very glad that it was useful to you.
have a nice day 🌺
@@Skill_DIY it stopped working 😢 nothing is wrong tooo
What motor did you use?
Did you put a sink for the MOSFET?
@@Skill_DIY I used a 755
This motor draws a lot of current and you need to use a large heatsink and a fan to cool the MOSFET because if the MOSFET gets too hot it will burn. Also, this circuit should not be used for a long time for this motor.
the motor may not start if trhe pot is turned down since gate voltage is low so max current would be low
Agar mosfet tidak panas bagaimana caranya?
Saya menggunakan irf44n dan potensio 10k input 12 v motor rs 550..
Tegangan mentok di 9v..
Panas saat motor mulai berjalan di tegangan 3v..
Mohon jawabannya..🙏
Gunakan heatsink untuk mencegah MOSFET dari kepanasan.
Saya juga merekomendasikan penggunaan Thermal Pad untuk kinerja yang lebih baik.
Apakah Anda yakin MOSFET Anda sehat?
Does it have high torque on low rpm
No
Can the MOSFET be replaced with SCR
No, because MOSFET and SCR have many differences.
Is ok for motor of dc 30v?
No, the MOSFET might burn out.
I want input only 4,2 Volt ...output 3-3,7 volt...can do or not ?
Hello, dear friend, welcome to the channel !
Probably, but this circuit is not suitable for this use
Bro, is heating normal? And 1 heatsink is good?
Hi dear friend.
Yes, at normal currents, the heating produced by the MOSFET is normal, and a heatsink is good.
Motors often have high inrush current so you must derate the MosFet
I don't understand what you mean, please explain more 🌺🤏
@@Skill_DIY which do you not understand.....you can Google motor inrush or starting current
I know the inrush current of the motors but I don't understand your solution.
@@Skill_DIY simple. if the nominal current is 1A with an inrush current of 5A then pick a transistor that can handle more than 5A
3.7 volt bhi lagasakte hi
yah sambhav hai, lekin sambhavatah yah theek se kaam nahin karega.
Would this work on a larger motor
If it is much larger than this motor, it will draw too much current, and the MOSFET may burn out.
@@Skill_DIY this would not work on an 18v power supply?
It will not work on 18V power supply, and the MOSFET will probably burn out.
Input 3v bisa tidak?
Untuk motor 3v, inputnya harus 3v.
Tapi untuk motor 12v, inputnya harus 12v.
Tapi rangkaian ini tidak cocok untuk motor 3V.
is that a LOG or LIN pot
I don't think there is much difference in using LIN or LOG potentiometer in this circuit, but it is better to use linear potentiometer.
Voltage drop 24to 9 when attach 12 v motor
How many input volts did you connect to the circuit !?
Where can we buy the parts?
You can buy parts from electronic parts stores or Amazon
Can i be use 100k potenciometer instead 10k?and using transistor
By changing the parts of the project, the circuit may not work properly.
If you use a 100K potentiometer instead of a 10K it probably won't be a problem, but I don't recommend it.
@@Skill_DIY tnx bro I'm going to used this idea..
nothing done in case of back EMF?
This circuit is simple and educational, but if you have any suggestion for this topic, please write it.🙏💡
@@Skill_DIY
With no explanation/discussion/advice/no coversge about issues the educational value is rather dismanl
I agree with you and thank you for pointing out this problem. 🌺
You can connect a flyback diode with the motor. and solve the back emf problem.
@@Skill_DIY I know so back to my original question
I said the solution above...
You can connect a flyback diode with the motor. and solve the back emf problem.
20volt ?
I don't recommend
