How To Make Simple DC Motor Speed Controller Circuit

[@Creativecreator]

Hey Guys what you are doing? One thing I should mention that you can connect Flyback Diode with the Motor. It will Protect the MOSFET from Back EMF. And Use a Heat sink for the Transistor. It will Heatup if you use it continuously. My Quarantine Time 😁😁 Visit: circuitbest.com/dc-motor-speed-control/

PLEASE DON'T TRY THIS. Don't you know that you're connecting the potentiometer 1st and 3 rd pin to the battery? The potentiometer will heat up extensively

[@rupeshpatil5568]

You are wrong my bro. The current will be limited by the resistance, if you calculate with ohms law only 12ma will flow.

[@willcrane6185]

sorry to ask, Why was a transistor used?

[@YeetTheAn3On]

@@willcrane6185 a transistor acts as a variable switch. The potentiometer cannot handle high currents, so it is used to control the input voltage of the transistor. The output of the transistor is based on the input of the transistor, thus, the potentiometer controls the transistor which controls the motor

Hi Creative Creator,Why did you add a Transistor to it. What is the use for it.

[@akongas]

I'd like to know too! Did you figure it out at all?

[@abinadvd]

Why not... From 12 V to 48 V. Not ok under about 8 V. In my mind the IRFZ44N accept about 50 V) 1) Use a radiator on the Mosfet or you will destroy it at half power after few times. 2) Never use more than 15 V on the gate or mosfet destroyed, you can add a resistor on the + of the potentiometer. His value depends on the potentiometer.

[@AitoLaikoSamoMoaCawfy]

yep using resistor and probably 555 timer ic would improve efficiency and using even a small heatsink will help the mosfet

[@abinadvd]

@@AitoLaikoSamoMoaCawfy You are talking about pwm. A 555 with diodes can do it , it is a classical . I mean changing the on/off ratio , the frequency is not important there. Dont forget a free wheel diode on the engine , if no , bye bye the mosfet. Of course pwm is better.In fact a transistor (or mosfet) must be used 100 % open (low resistance) or closed once you can. At 50 % ( Imax/2, Rengine=Rmosfet) it is like a resistor and heat same as the engine. Without a radiator on this little thing , good luck. This video is for fun and show what a mosfet under 50 cents can do. It is impressive if you never did it.

Great tutorial. Could you use this setup between a Brushed ESC and a motor as a speed regulator? As in limiting the max speed of your motor output.

[@tonywright8294]

No it’s against the law

[@Patrick-rj8gh]

How does this work? there's no PWM control here. As the gate-source voltage drops below the threshold wont there will be excessive heating on the mosfet?

[@ravindrajagtap43]

yes

[@theultimatetime8029]

Its not an efficient idea but you can use it with adopters.. batteries could drain a bit faster than expected in less speed...if you are using less voltage or high voltage application it doesn't matter..it takes same current all the time..in lowest currents the mosphet can become hot

It is not about max voltage bro it is about current. This is about some mili Amps. If you say about voltage then i will say if you want to vary speed of a motor then 3 to 5v without mosfet. 12v for dimming leds 😉

Do you just flip the MOSFET? I'd like to know 😊

[@bernardocisneros4402]

Hi, I'm just getting started in electronics. What is the purpose of using a mosfet? What would happen if only potentiometer was used?

[@YeetTheAn3On]

potentiometer will burn due to high current. The MOSFET acts a variable switch that changes it's voltage while being able to support high amperage. The input or gate of the MOSFET is controlled by a potentiometer which cannot support that much amperage.

[@bernardocisneros4402]

@@YeetTheAn3On Thanks! I get it now. It's like using a switch to control a relay. The potentiometer is the switch and the mosfet is the relay

[@AlexChipman]

What is the transistor doing? Does a potentiometer always have to have a transistor attached?

[@satvindersiddhu4911]

How else would you vary motor speed

[@MaxC_1]

it's a power transistor and a potentiometer cannot take the amount of current (considering most are rated at around 0.2W) so a power transistor allows higher currents to be driven depending on components used

AoA sor, I made one and it worked but despite of heat sink attached, the transistor LM317 ended up pretty hot, it also turned the heat sink too hot to touch. I was using 12v 48amp solar battery as power source. Any solution for this?

[@Creativecreator]

This circuit is a linear converter, so if you try to use the circuit for higher current output then it will eventually heat up. Then you have to use any type of buck boost converter for controlling the motor speed. This circuit is good for 1A constant output. You can also use a circuit where 555 Timer is used for generating pwm pulses and it drives a n channel mosfet. And that mosfet is used for powering the motor. Specially here all current handling part is done by a mosfet. So it can handle much amps (5-10A). Happy Building 😊 Don’t forget to subscribe:)

[@Creativecreator]

Use buck boost converter

[@joshnabours9102]

Or a boost circuit works too. A buck converter converts higher voltage dc to lower voltage dc, boost converter converts low voltage dc to high voltage dc, and buck boost converter can convert a high or low voltage to a higher or lower voltage. Buck boost is required if supply(battery in your case) will provide a voltage within a certian number of volts of what you want at the output since boost converters only can supply voltages greater than a few volts above the supply and buck converters only can supply voltage at or below supply voltage ( minus diode voltage drops).
