Hi dear friend! I am very glad that it was useful to you. have a nice day. 🌺🙏

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

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.

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

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.

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?

Can the MOSFET be replaced with SCR

No, because MOSFET and SCR have many differences.

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

@Skill_DIY

Ай бұрын

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

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

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.

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.
