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.

Maximum 12v ?!! Or it can be 24
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
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.
Полевик в линейном режиме, звучит горячо
Все в порядке - он же приклеен на суперклей 😅
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..
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 !!!
Tu devrais garder tes commentaires pour ton propre système critique
Si ça ne te plait pas, n' en dégoutes pas les autres.
Y en a à qui ça plait, ou qui y trouve des bonnes idées, voire, d' excellentes idées !!!
@@guyallavoine6815 t’a rien compris toi tg
😅procede
That's great! Heater + fan + a speed controller!
Nice! 👍
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
I'm pretty good at soldering, but this cat is a samurai. Nice video.
Dá gosto ver um profissional fazendo uma solda perfeita
No hot glue was harmed in the making of this short.
Oh wait they used it for the propeller.
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.
Регулятор которому нужен радиатор для охлаждения приклеивают на моторчик, который постоянно греется. Классно😊
Autonomía infinita. Algo que las industrias no quieren que se sepa. Saludos.
Excelente simple fácil pero muy útil, gracias por compartir
nice

Good to see so many people know the problem! Lol I came here to comment the same things I’m seeing
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
Se ahorra el trabajo con el solo potenciómetro pero está chévere
Que potência. Legal!👏🏻
இதே மாதிரி போடணும் மற்ற பத்தி 🙏👌❤️❤️
Love the Music
Hexfet and active mode, you are genius.
This is why people go to engineering school.
no, this is why people snap and do mass shootings.
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 is the need of the capacitor? Nice work 👏🏼👏🏼
I suddenly feel the urge to install a fan to this and use as a mofset cooler internally 😂
Mosfet is a voltage control device. 🙂
A potentiometer acts as a voltage divider to control gate-source voltage
Salama po dahil nagawa ko din ang ginawa nyo na dc motor
Never use fevikwick on surface which gets heated😊
what a clean finish! 🤙🤙🤙
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
Ingenioso 😊
я поначалу подумал что опять вечный двигатель изобретает а нет все норм
Very nice
I installed one of these with a propeller as a kid on my plastic battleship. I sailed away… forever 😂
Bisa berguna kedepannya utk pengembangan dunia automotif
i search this much time ago , ty bro
Wow! Amazing!
Wow wow beautiful ❤❤🤝👍

Superb
So nice 👌 i like it superb
Hi 🤔👼
Exelente
Подойдёт любой транзистор средней мощности, а схема также, электронного ключа!
قشنگ بود و کاربردی 🙏👏
❤How interesting
В старину для этого использовали самый обычный проволочный реостат)
🎉thanks
Спасибо🎉🎉🎉
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.
❤❤❤ phoni first uspe happy food cc bill Gaya yaad
Parabéns irmão arrasou em na Estalacao eletrônica vc e um Jenio
Транзистор транзистор и конденсатор для красоты.😂
من المعروف أن الموسفت يوضع في مكان يقلل من سخونته ، ووضعك إياه فوق محرك سيتلف المنظومة لا محالة 👌🇩🇿
Good idea
Dude is going to fry the whole rig.
These electric motors gets crazy hot under load.
Крутая регулировка на паяльник дешевый
Этот чел гений, больше нечего сказать 😂😭
Идеально для помех " связи" . проводники забыл по 5 см
No turning back ❤
a place for my head intro 😵💫

Best of Mosfet 👍
Only the potentiometer is really needed
exactly lol
Pot can't handle that much power
when motor become a heat sink of transistor 😂
Красиво сделал!
Nice,but what was the purpose of that capacitor?
For current stabilization
О нет, они придумали линейный регулятор! Колдовство кончилось!
Está dissipando o calor do Mosfet na carcaça do motor! Vai superaquecer se o motor trabalhar com carga.
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
Сопротивление другой группы надо с более плавным регулированием
Top demais 👏
По часовой стрелке, увеличение частоты вращения
Awesome bhai ❤❤❤
😂❤
это первый класс!
кто узнал мотив, ставь лайкос
Cool
Fmz tô ligado meu deus 😊
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.
Awesome
Este tipo es un mostró
Pero más mostró es quien invento todo eso repuestos que el utiliza para hacer que eso funcione
Оооо,ёпт,получился обогреватель мини,для ладошек,с вибрацией
Nice
Super
"Perfectly" utilized all the good MOSFET characteristics l... Please give us thumbs down count back.
How long do you think before putting a MOSFET directly on a motor?!
it will be a barbeque party 😂
А кто нибудь может обозначить предназначение этой конструкции,.....😅 , облака разгонять или бешеных диких тараканов 😂😂😂???
Для шортса нормально)
Nice.
Muito top
Sell us real tools, they sell crappy soldering irons this side. You can be waiting for days to solder just one terminal on that potentiometer. You have made it look so so easy.
استمر بنشر ❤❤❤👍👍👍👍
Молодец, что не написал в названии ШИМ регулятор
Muito útil
SUPER
Epiiiiic
Eu não colocaria o Mosfet colado no motor, mesmo que a potência não seja o suficiente para uma super aquecimento
Por que?
