Making a Powerful PWM DC Motor Speed Controller 12v 10A || Concept of Freewheeling Diode

[@colinmcintyre1769]

I was about to jump into this thinking, how hard could it be, chat GPT got me way to hiped 😂. Thank you for this video, and I got to 8:46 before I snapped out of that learning haze that's just magic, thank you for that. You really saved me a lot of head ache amd heart ache, knowledge is crazy in how it can be passed on so easily, yet not.

[@guyconiglio8223]

You have saved me so much frustration! I am so glad that I didn't try making my pwm circuit before I saw your video.

[@paulboberg5512]

Yes I learned what I needed to know, thanks. It really helped that you didn't edit out your failure, instead you showed how you diagnosed it then solved it. I have found that my failures are often my best teachers.better yet you're failure was a exalent teacher.

[@0ii076]

Perfect timing that I found this video, what a godsend! Many thanks!

[@aseerahmad2671]

does it work with 9 volt dc battery?

[@jaffasoft8976]

Thats cool how the back the board solered all the joins together. Neat and tindy didnt know could do that. Also that is can be a light dimmer, now im going to see if i can find a kit to dim my lights as well as slow my dc gear oil pump motor.

[@yousefLa52.]

What can be installed as a replacement transistor for IRFZ44N ?? I thinking about the IRF630 ! What do you think???

[@javeedrasheed]

u can install any n channel mosfet , (75n75 , 3205 etc)

[@threeiem]

This is great! Thanks for showing how you problem solved this. :)

Good vid. The actual live oscilloscope view showed us definitively what's going on too.

Whoo I am glad I found your video. I am trying to make one too to control a power mosfet irlb3034 for a vape device and 100nf ceramic cap to produce a lower frequency. The problem is, it doesn't change the power. It always is on 100% power. Do you have any idea as to why?

Hi. i want to make this pwm control for a 3.7v low ampere 10mm x 6 mm mini dc motor.can i replace this mosfet with a smd type bc547 transistor?

[@desislavkanev9613]

I construct this schematic, it works and It is very simple. But i have an idea - i want to replaces the potentiometer with thermo resistor / 10k omh / and the speed will be based on temperature. But is it possible to make the motor to run aprox. 40% / idle,not depending on temperature/ and the thermo resistor to control the speed of motor in range 40-100%…. Is it possible to change the schematic to work like this?

Excellent!!! You are a professional, but I am wondering why you didn't use a IC base on GP pcb so that you can easily replace the IC, whenever required.

[@klausbrinck2137]

What would I have to do, in order to get 15kHz, instead of just 10kHz ??? What would I have to do, in order to get 20v output, instead of just 12V (Amps are irrelevant, 0,1A output would be enough, instead of 10A as in your case) ??? Must I simply change the source for a 20V-source??? All I need to do, is to drive an igbt, instead of your mosfet (needs 20V, but needs nearly no current at all, to be driven). Otherwise, well done video, and thanks for any answer !!!

[@TifinDragoshP-]

@klausbrinck2137 You are going to need a separate voltage supply for the igbt, because 20v is exceeding the 555 timer voltage range, so I would recommend you to either use the same schematic, with a different, higher voltage mosfet and feed the 20v source to the output, instead of the motor(load) or just use a discrete igbt driver and supply it with the 20v. For a different frequency you'll need different capacitors with less capacity and probably a different variable resistor, I intend on using the same 15kHz frequency and will add to this comment if it works out.

[@harsh7.30]

It's posible than using 4n25 or 4n35 optocouple and fga25n120 igbt to control high voltage rating motor Optocouple use for isolation between power and control circuit Also use for switching

[@sangrambhumia9320]

I have a transformer of 12 volts which only outputs max 500 milliamps may be due to it's high internal resistance. But i want to run a motor at 5 volts with 1amp .is there anything i can do?

Personally i use only two-transistor multivibrators to drive the Mosfet since it has two outputs.

[@londam2405]

@Aatik's lab awesome video! Definitely useful for me and answered a lot of questions. A noob question though. If I'd want to get 24V 10A to a DC motor (instead of 12V 10A), what would I have to change (apart from the power source of course)? Which components I'd have to change in order not to fry them with higher voltage? I guess the schematic would be the same, I'd just need to place tougher components?

Better way is to use a proper havle H-bridge between the 555 timer circuit and the motor, 555 timer can only sink and source a limit amount of current.

SOS please help. Hello friends. I designed a program with my Arduino to run a 5 to 9v dc motor forward, stops and backwards for a few seconds. Then stops and waits for sensor again. The code was put into an IC ...the AtTiny85 to shrink the project. Here are the component's...9vdc battery, .i used a PIR sensor to detect motion as input. Im using a LM7805 (100 nf electrolytic cap at input and 0.1 nf ceramic cap at output) regulator to reduce voltage to supply IC with 5vdc so it can go into program. The outputs of the program are .. light up an LED ( with a 200 omhs resistor) and start the motor by giving signal to small DX1616 Motor Driver. Tge mot Also , during this operation, the system can be shut if a Microswitch is pressed. MY PROBLEM: the code, and this system works perfectly on breadboard. But when i solder it on card...it works for a few minutes and the motor starts spinning only fwd non stop AND ITS LIKE THE SYSTEM DOES NOT GO INTO PROGRAM FROM THE ATTINY85 or not enough current to start it. Everything (sensor, driver, motor) takes power from the 9v battery , only the AtTiny85 is supplied with regulated 5vdc but that input to the regulator also comes from 9v battery. Could my capacitors be the problem? Is 100 nf too much at that input and dissipates all the energy?? Should i also separate the grounds of the circuit. The 9vdc circuit and the AtTiny85 circuit SHARE the same grounds. Thank you

It only works in small motors. Not works with 12v 9amp motor. Transistor damaging always

if the problem is coz of heat, then Use a heat sink for the transistor

not because of heat. Because of overload

[@vusiliyK]

1.) You should never solder an IC directly into a PCB... use a socket. 2.) The free-wheeling diode is part of every motor control schematic online so never say "I KNOW my circuit is correct so it must be a bad component 3 times in a row". Do more research first.
