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. ❤

What motor did you use? Did you put a sink for the MOSFET?

@electro_kid1 5 месяцев назад

@@Skill_DIY I used a 755

@Skill_DIY 5 месяцев назад

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.

@ThisIsAllFake Год назад

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?

@Skill_DIY Год назад

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.

@kennmossman8701 Год назад

the motor may not start if trhe pot is turned down since gate voltage is low so max current would be low

@Nazgul1221 4 месяца назад

Bro, is heating normal? And 1 heatsink is good?

@Skill_DIY 4 месяца назад

Hi dear friend. Yes, at normal currents, the heating produced by the MOSFET is normal, and a heatsink is good.

Can the MOSFET be replaced with SCR

@Skill_DIY 10 месяцев назад

No, because MOSFET and SCR have many differences.

@hermandebruin1334 Год назад

Does it have high torque on low rpm

@Skill_DIY Год назад

@kennmossman8701 Год назад

is that a LOG or LIN pot

@Skill_DIY Год назад

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.

You can buy parts from electronic parts stores or Amazon

@kennmossman8701 Год назад

Motors often have high inrush current so you must derate the MosFet

@therealsirbassalot 11 месяцев назад

Would this work on a larger motor

@Skill_DIY 11 месяцев назад

If it is much larger than this motor, it will draw too much current, and the MOSFET may burn out.

It will not work on 18V power supply, and the MOSFET will probably burn out.

Gunakan heatsink untuk mencegah MOSFET dari kepanasan. Saya juga merekomendasikan penggunaan Thermal Pad untuk kinerja yang lebih baik. Apakah Anda yakin MOSFET Anda sehat?

Untuk motor 3v, inputnya harus 3v. Tapi untuk motor 12v, inputnya harus 12v. Tapi rangkaian ini tidak cocok untuk motor 3V.

Can i be use 100k potenciometer instead 10k?and using transistor

@Skill_DIY Год назад

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.
