An explanation of H bridges (a type of motor control circuit). I also show you how to build a bidirectional motor speed controller.

Hello ! , thanks for sharing this knowledge ! :) , helps a lot ! ; Just have some questions please, help !
Please I want to ask you,
- Can I use another diode , replacement instead of the 1N4004 ? and the same for the MOSFETS ? , can I use replacements ?. which ones ?
- What is the voltage on the 1000uf capacitor ? and Resistors ?
Thanks a lot again !
Will wait for you answer to go to the electronic shop , can´t wait :D
Greetings ! -
If I make a PWM circuit, can I use hall sensor instead of a potentiometer ?
-
I used irf540n and irf9540n and n channel mosfets become very hot. But circuit vorks properly? Please can anybody help me why they are becoming hot?
-
Thanks for the info. great video, one question:
What elements in the circuit should I change to make it work safely with a 24v 100w DC motor? I just want to control the speed of motor, reverse not necessary. Thank you. -
Can you show us how to find the Kn and Kp factor of the NMOS and PMOS on datasheets? Did you use it to find the drain voltages assuming the triode operation?
-
why don't you just use a dpdt switch and wire it to invert the voltage polarity?
-
Is it basically a Brushed ESC?
-
or just put an non electrolytic cap on the motor that is about 1000uf and has 2x v-in rating and working voltage
-
hi, I am trying to copy your circuit to 3 dc motors (with reductions ), but the 3 IC 555 gets too hot, I am using 2p2t swicth for each motor instead of transistors, ac/dc adaptor 12v and 0.3 amp as power supply, what do you advice me ?? thanks in advance
-
Could you use a small capacitor to smooth out the square wave through the motor, and thus reduce the 1Khz whine? Also, does attaching an inductive load directly to a mosfet, and feeding through a square wave, risk damaging the mosfet?
-
Hi there, I love how you explain your process! Thanks so much
Is there any way to use a H-Bridge to control a DC motor and make it spin and stop at 4 or 5 separate points? Something that could operate a 4 way valve? Sorry I just have to ask... -
I’m a software developer and I came here to kinda relax my brain a little. Now my brain is more tired than it originally was. In another life, I’d like to be an electrical engineer.

+Afrotechmods the arabic subtitles are a joke. The maker literally translated "motor" as a fucking car!! and "H bridge" as a literal car bridge! Power as in literally power (i.e. person in charge) wtf... it's seems auto generated

Good Job!
I have a question. What about controling 24V load by a Mosfet (Vth=4 V)? -
question is what the voltage on that capacitor? i wonder the same for those 103 ceramic capacitor at the store they asked that so i ask that too xD
-
What would happen if we used lipo what would happen?
-
How can you use this with an Arduino controlling the logic? Like with only 2 wires, for PWM each direction. Also how would you stop the motors from spinning? This method you show would need 3 wires to control from an Arduino right? A PWM for the speed, plus which direction its going? Have not been able to find any specific info on how to turn the motors off when only using 2 wire control..

could you please review your cat
