A motor speed controller circuit is an electronic circuit that is designed to regulate the speed of an electric motor. There are various types of motor speed controller circuits, each with its own unique design and operating principle.
The most common type of motor speed controller circuit is the Pulse Width Modulation (PWM) controller. This circuit uses a microcontroller or other control circuit to generate a series of pulses of varying widths. These pulses are then used to control the power delivered to the motor, thereby regulating its speed.
Another type of motor speed controller circuit is the DC motor speed controller. This circuit uses a variable resistor, such as a potentiometer or rheostat, to adjust the voltage supplied to the motor. By varying the voltage, the speed of the motor can be controlled.
A third type of motor speed controller circuit is the AC motor speed controller. This circuit uses a variable frequency drive (VFD) to control the speed of an AC motor. The VFD adjusts the frequency of the power supplied to the motor, which in turn controls its speed.
In all cases, motor speed controller circuits are designed to provide precise control over the speed of an electric motor. They are commonly used in a variety of applications, including robotics, industrial automation, and home appliances.
The IRFZ44 is a type of power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) designed for high-current switching applications. It is manufactured by various companies, including Vishay, Fairchild Semiconductor, and Infineon Technologies. The IRFZ44 features a low on-resistance (RDS(on)) and a high drain-source voltage rating, making it suitable for use in a variety of applications, such as power supplies, DC-DC converters, motor control, and lighting control.
The IRFZ44 has a maximum drain-source voltage rating of 55 volts and a continuous drain current rating of 49 amperes at 25°C. It has a TO-220 package with three pins, including the gate, drain, and source. The gate threshold voltage typically ranges from 2 to 4 volts, and it has a fast switching speed, making it ideal for high-frequency applications.
One of the key advantages of the IRFZ44 is its low RDS(on), which helps minimize power dissipation and improve efficiency in high-current applications. Additionally, it has a robust design, allowing it to handle large transient currents and voltage spikes. Overall, the IRFZ44 MOSFET is a versatile and reliable device commonly used in power electronics applications.

Oh great! Glue a transistor that heat up like a pan to a motor that heat up like a pan

Don’t blame him, he’s a 3rd world coolie….
@@usmanballo7621Can confirm. Education is a joke here in the third world.
First I read/understood your comment wrong and was like "I dont understand, what is wrong with the capacitor and the motor"
And then I read again and saw again the video to realize he did what he did with the glue hahah
Altough i wouldnt say its because he is a "third World dumbass" as some try to say here. Im just a newbie for example, and altough I know both heat up, I might do the same mistake because of not thinking and just thinking on the circuit (like i was doing watching the video, I didnt think about the cooling, just wanted to see the circuit)
Just a newbie mistake or not thinking straight, sometimes you just do something dumb because the process is easy and you underthink the solution
That's not how you use a MOSFET, it's either fully ON or fully OFF, I'm sure this will heat up really quick
Won't a P.I.D controller be a better option? Or even a HFO?
Mosfet analogue Audio power amplifiers would like to disagree about them being only digital. Linear operation is a thing.
@Raymond Casso mmm PID is mostly to adjust physical parameters like temperature or pressure. For a small applications like this you can still use the MOSFET but you would use PWM to change its duty cycle and have a more accurate control without passing high current through it
@@TheMoeP PWM mode is where you pass higher current intermittently and linear regulation is when you pass lower current constantly to achieve same effective power.
PID is just way of including a feedback loop, which has nothing to do with the use of mosfets. PWM control could also be less accurate compared to this as for example Arduino has 8-bit default PWM resolution while this potentiometer is purely analogue. Maybe what you ment is "PWM would be more linear".
All in all, the mosfet here acts as a variable resistor that is made to dissipate more power compared to what power you could dissipate over the potentiometer.
@Šimon Kondrk linear amplification is less efficient and with more power dissipation as heat, you would need a good heatsink, while it can be more accurate for certain applications it's not the best option for low power applications. PWM has higher efficiency but with the problem of EMI and some vibrations. Overall it depends on your application, for small stuff like this (in my opinion) PWM would give you better driving
someone get this man a breadboard
You're really so desperate for upvotes you'll continue this lame copypasta?
it's on _every video_ it's not funny more than once.
The bread is on me
@@nibzlegend99 😊😊😊
Real
I'm pretty sure he does that so we can understand better anyways that's not how u use a mosfet
Honestly, i think these channels only exist because of the shitloads of arguments they know they'll cause in the comments...and i gotta say, im here for it
Imbécilité crasse !!!

This video screams *"I don't know what I'm doing!"*
Voltage de entrada por favor gracias
Your comment proves, you don't know what you are looking at.
他自己也不懂
If he doesn’t know then how did he make it work you duffus
@MrRobarino it's either fully on or fully off otherwise it would overheat. dummy.
the idea of using the motor as a heatsink was genuine.
I don't think he intended for the motor housing to be the heatsink since he used superglue instead of thermal glue. The mosfet is likely to be fine in this usage, but bad practice since it'll overheat.
If it was intended as a heatsink then at more voltage and amps motor will heat up and the mosfet will also so not for long usage
It's not, this is an example circuit, it was done for ease of demonstration and looking cool.
For those that think this circuit is dumb, the mosfet is simply in a common drain configuration to act as a voltage buffer, eliminating the loading effect on the potentiometer. Good work 👍
He could use a regular transistor
how's that work?
edit:
Ok, i read the circuit wrong. The pot is controlling how much electricity the mosfet let out, therefore, controlling the speed. but isn't it dangerous to run motor without flyback diode?
So the motor voltage would be lower without the mosfet?
I also agree there should be a back emf protection diode..
Полевик в линейном режиме, звучит горячо
Все в порядке - он же приклеен на суперклей 😅
Nice,but what was the purpose of that capacitor?
For current stabilization
@@gabtechexpo4017Thanks,but how a capacitor works as a current Stabiliser?
I remember when i was obsessed with the dc motor in grade 6 & wanted to make motor boat.
me too, I built a submarine out of a soda can and some Rc car electronics when I was like 6 years old
Debe usarse un regulador de voltaje y no un MOSFET, de la serie LM217, te da voltaje de 1.5 hasta dis voltios menos que el voltaje que dé la batería.
you don’t need a mosfet you know
Why?
@@musicearth3395 potentiometer alr gives control over voltage. MOSFET is useless
@@iammeobviously6815 Ohh thanks for clarifying dout bro
@@iammeobviously6815that's a lie if you don't know better don't say
@@usuario448 seriously? I use it without a MOSFET ALL OF THE TIME AND ITS FINE
Good to see so many people know the problem! Lol I came here to comment the same things I’m seeing
No hot glue was harmed in the making of this short.
Oh wait they used it for the propeller.
I'm pretty good at soldering, but this cat is a samurai. Nice video.
This is why people go to engineering school.
no, this is why people snap and do mass shootings.
Can't we use 5k instead of 10k potentiometer?
Yes. The speed range will be different
there will be no difference if your using the potentiometer as a voltage controller.. you can use any value (1k to 100k) i think
nice
from Gilgit-Baltistan❤
What is the need of the capacitor? Nice work 👏🏼👏🏼
Is it appropriate to use these mosfets in linear mode?
The potentiometer on its own would be able to control the motor speed, a transistor is not necessary.

@@isaachenrikson3197 yeah it'gonna burn bro
no, at best you have to use one with high rds on
@@tiagoferreira086 sorry
I suddenly feel the urge to install a fan to this and use as a mofset cooler internally 😂
Autonomía infinita. Algo que las industrias no quieren que se sepa. Saludos.
Excelente simple fácil pero muy útil, gracias por compartir
The question is how you soldered so smoothly? I am struggling in this. Any tips?
lots of practice. use leaded rosin core solder. use a very hot ~ 700 - 720 F iron.
Once you know how your iron moves heat through a joint, ou will develop a feel and be able to use a minimum amount of solder.
Once the whole joint is hot, the solder will flow, and if you are fast, coat thinly and evenly.
Keep you iron tip clean and well tinned. Use a damp sponge to clean oxide off as you work.
Having magnification to really see what the solder is doing is very helpful too.
@@jhoughjr1 Thanks for sharing.
You know the MOSFET and the motor will heat each other up don't you?
The MOSFET needs a heat sink and the motor is in no way a good heat sink
The life of the motor and the MOSFET will be very short if you use this setup...
Knowledge needs wisdom lol
he should just use a BJT
I see a small fire after the motor burns out. 😂
why mosfet ..... i have used POT directly to control small lo voltage motors.
Low resistance wire wound I assume
With only de POT the wasted energy for Joule effect would be higher. He could use a transistor though
Que potência. Legal!👏🏻
Dá gosto ver um profissional fazendo uma solda perfeita
Регулятор которому нужен радиатор для охлаждения приклеивают на моторчик, который постоянно греется. Классно😊
This MOSFET includes the diode protection. The circuit is complete with only 3 components. The capacitor filters piks parasit.
P E R F E C T
what a clean finish! 🤙🤙🤙
It's working ❤❤❤😊
Is it a mistake 😂 and it is the transistor being soldered on the motor and the motor is overheating, which leads to damage to the transistor. The transistor must be soldered on a piece of aluminum iron in order to help cool the transistor
Mosfet is a voltage control device. 🙂
A potentiometer acts as a voltage divider to control gate-source voltage
Seems like this stupid trend of using a mosfet incorrectly in a linear mode is out of hand. I've seen too many vids like this lately
❤❤🎉😮❤❤❤🎉
من المعروف أن الموسفت يوضع في مكان يقلل من سخونته ، ووضعك إياه فوق محرك سيتلف المنظومة لا محالة 👌🇩🇿
Love the Music
Hey, put a scope across the motor to observe if just the voltage level is affecting the speed or if there's a frequency component.
Hexfet and active mode, you are genius.
Идеальная конструкция что бы спалить транзистор он его приклеил к мотору который СУКА НАГРЕВАЕТСЯ
Зимний вариант , просто
Да сам транзистор в не правильном режиме работает. Он у него полуоткрытый получается а это лишний нагрев.
قشنگ بود و کاربردی 🙏👏
இதே மாதிரி போடணும் மற்ற பத்தி 🙏👌❤️❤️
So nice 👌 i like it superb
Hi 🤔👼
I installed one of these with a propeller as a kid on my plastic battleship. I sailed away… forever 😂
i search this much time ago , ty bro
Этому мотору достаточно обычного переменного резистора
Во во
Этому мотору давно пора поставить памятник
Переменный резистор при маленьких сопротивлениях сгорит . Нужен постоянный резистор .
Если простой переменный, то с большой мощностью рассеивания, а так просто сгорит
@user-fi3jg6fx7r it's better if they put a variable resistor in series with a fixed resistor to set a minimum resistance
Salama po dahil nagawa ko din ang ginawa nyo na dc motor
Nice! 👍
Есть ли вариант использовать что-то вместо мосфета? Так как он очень сильно греется
В линейном режиме будет греться все. Используй ШИМ и будет тебе счастье и холодный транзистор.
@@ВладимирИванов-м8б2л я только начал создавать схемы шим можно просто купить в радиодеталях?
@@tweertle есть готовые контроллеры в виде собранных плат. Есть удобные микросхемы, например NE555 - вот на них можно собирать.та любой линейный регулятор избыток энергии на себе гасит, потому и греется, а полевой транзистор в линейном режиме еще и из строя легко выйти может.
@@ВладимирИванов-м8б2л то-есть подключить просто через шим и всë будет работать и не грется? А что понадобится для того чтобы управлять яркостью лампочки 220в?
@@tweertle для переменного тока, а конкретно для лампочки нужно использовать фазовый регулятор мощности на симисторе.
Someone could explain how the circuit works?, not really sure why the mosfet was needed nor the capacitor
Trust me, Just forget what you saw here. If I explain to you why he puts them and what's function for each one, you will understand that this is what should never be done.
The only thing you need to know is that this "fake" circuit is so poorly made that it doesn't regulate speed finely (See that it accelerates from little to 100 with almost no movement) and the MOSFET is bound to die from overheating and reverse voltage.
❤❤❤❤❤🙌🙌🙌🙌🙌👍👍. Love the layout...
Wow wow beautiful ❤❤🤝👍
Bu devreyi transistör kullanmadan da yapamaz mıydın? Neden Transistör kullandın?
kanal sahibi türk mü?
Transisörsüz olursa devre çok daha vermsiz olurdu
Bisa berguna kedepannya utk pengembangan dunia automotif
What if I just use 3V (2x1.5V AA size) power battery? Should I minimize the size of potentiometer and the other things?
3V may not be enough for gate of mosfet
Does this work with negative DC voltage too? Does the motor spin in reverse side if negative voltage is given?
What was the need for the mosfet in this system? Will a potentiometer always output a voltage unless gated by the mos?
Very nice
Does It Protect From OverLoad
линейный режим - это утюг, странно что мосфет сразу не вышел из строя, нет ни керамического конденсатора ни обратного быстрого диода
Всё в порядке, мосфет же приклеен на суперклей!
Нихрена ему не будет при такой мощности. А вот в нагрузке будут проблемы
Wow! Amazing!
when motor become a heat sink of transistor 😂
Se ahorra el trabajo con el solo potenciómetro pero está chévere
a place for my head intro 😵💫
😊😊😊
M yes Troom-troom of circuit world
It doesn't make the dinamo faster, it just make it slower or to it's full speed by decreasing the voltage. It can't increase the voltage
Benefit of mosefit?
What kind of bettery did you youse?
Good idea
Awesome bhai ❤❤❤
😂❤
Never use fevikwick on surface which gets heated😊
я поначалу подумал что опять вечный двигатель изобретает а нет все норм
Best of Mosfet 👍
You don't want to have the heat sync in contact with the motor or it will get damaged
The can of that motor is not connected to anything! So, not an issue
What soldering iron do you use and with what type of tip?
🎉thanks
this will make mosfet very very hot and burn. use PWM for speed control. never use mosfets in linear region.
Está dissipando o calor do Mosfet na carcaça do motor! Vai superaquecer se o motor trabalhar com carga.
Let me ask one more thing.
Does a power supply direct to outlet or there is a battery so that motor can run?
Runs straight off of 120v 60Hz like good god intended. Try it out, you can use any transistor with 3 pins.
Superb
Working voltage and current details. Whether 12 v dc?
Does that circuit also works for a dimmer?
You can build a fan with this circuit
Зачем городить огород было? Один только переменный резистор точно также работал бы. Транзистор там не нужен, и конденсатор там только для снятия помех (которые и так мизерные) будет работать.
Для ролика. Больше это никуда.
Ну типа ключевой режим
I hope my girlfriend can handle the extra "heat" from the mod I just made to her "rampant Rabbit" hahaha.
Parabéns irmão arrasou em na Estalacao eletrônica vc e um Jenio
mos管不是控制负极的吗？不需要加一个10K电阻吗？
Eu não colocaria o Mosfet colado no motor, mesmo que a potência não seja o suficiente para uma super aquecimento
Por que?
Por que?
Dude is going to fry the whole rig.
These electric motors gets crazy hot under load.
What course should I take to learn how these parts work?
How long do you think before putting a MOSFET directly on a motor?!
it will be a barbeque party 😂
This transistor will heat up very quickly, its not controlling its speed, its converting some energy into heat so motor spins slower
Hello, I made this circuit and it works, but when I fully open the potentiometer, the motor does not work with full power. Can you help me with this?
это первый класс!
кто узнал мотив, ставь лайкос
If you plug it directly to the power supply spin's at full?
Nice profense
Only the potentiometer is really needed
exactly lol
Pot can't handle that much power
Where does the electricity source come from? Is it from the transformator? Please help answer. I want to make it
What is the use of the mosfet in this case?
