Can I use IRFZ44N Mosfet for the project? If no then can you recommend any other mosfet please.
Not recommended. You must use logic level MOSFET that can fully turned on with the 5V logic level.
So any logic level n-channel mosfet is ok?
Yes with appropriate current rating.
@@Circuitdigest example STP55NF06
just curious, why do we need an arduino for this? can't you just use mosfet + pot and it will function the same?
If you use the mosfet with just a pot without the PWM, you control only within the ohmic region.Even there you would be wasting energy since the mosfet will act like a resistor and will generate a lot of heat.
10qs sir!I want to do this project how much money I have to invest?
Hi, Components required are listed on the project page you may use that to check the total cost.
What are those resistors for ? What is its use ?
Pull down resistor is there to make sure that the MOSFET is fully turned off and the gate resistor is used to control over-current in gate drivers and to reduce overshoot between the drain and source during switching (EMI noise-reduction). The switching time (rise and fall time) of MOSFET varies depending on the resistor of the connected gate.
@@Circuitdigest Why not explain it in video and make it simpler to understand?
Doesn't mosfet already have inbuilt diode
The flyback diode is connected across the motor not across the mosfet.
1k for gate is really high. Gate resistor should be around 20 to 50 ohms
With minimum Vtgh and rise time of 10nS, Ig = (1470pF * (5V - 2V)) / (10ns) = 0.42mA. With 1K resistor the current limit will be 5mA at 5V. So the 1K resistor is more than enough and will work just fine.
Can upload automatic motor speed decrease
That what shows at the beginning of the video
