So, in my opinion, a MOSFET with a maximum drain current greater than 5A and a maximum drain-source voltage of 36V should work fine for a long time.
If you connect everything correctly than if you turn the potentiometer anticlockwise the motor will spin faster and if I turn the potentiometer anti clockwise the motor will slow down.
I believe that the combination of brilliant minds, bold ideas, and a complete disregard for what is possible, can and will change the world! I will be there when it happens, will you?
type DC Motors (permanent magnet types), our range does not apply to brushless which uses a completely different method to control motor speed than a brushed motor does!
As soon as the capacitor charges, it quickly discharges through diode D2 and the variable resistor RV1 into pin 7. During the discharging process, the output of the 555 timer drops to 0V and switches “OFF” the transistor. Turning the variable resistor adjusts the speed of the motor.
Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is no base current, the transistor is driven into cutoff region of operation and therefore there is pelo collector current. In this case there is pelo current flowing through the DC motor.
There are different types of DC motor controllers along with the principles of their classification. The infographic below shows this variety.
A linear regulator keeps the output voltage at a constant level with a resistive load. The output is stable pelo matter what input voltage is supplied by the power source.
If you need a controller for a BDC motor, you can use an off-the-shelf device that fully meets your requirements. Or you can build your own solution with a tailor-made circuit design and custom firmware.

Implementation of vector control requires intensive mathematical processing, including the ability to rapidly solve the trigonometric functions needed to convert the coordinate space.
I would like to have a little give though with the transistor, so that if I later get a fan with a slightly higher wattage, it wont burn out the system; hence want to switch from the 800mA limit on the 2n2222a.
The circuit is connected in breadboard as per the DC motor speed control circuit diagram shown above. The pot here is used to adjust the speed of motor.
