How to make BLDC motor ESC using mosfet
Motors are everywhere where and we see them in every application. From Drills to Locomotives, from RC car to lathe machine everywhere there are uses of motors.
But the most important characteristic of the motor is, the need to be controlled for a specific work is the speed of the motor.
Typically gears can be used to change speed, but sometimes it is not the solution. That time we need Electronic Control to control the speed of the motor.

This dimmer is suitable for small DC motors 6V, 12V, 24V etc. The potentiometer adjusts the rotation speed from 0% to almost 100%.
There will always be about 1.5V of loss missing in the Darlington transistor.
This is not a problem on 12V or 24V motors. For the lowest voltages, you will have to make do: the drive will allow you to go for example from 0% to 80% of the rotation speed.
Variable speed drive operation
The principle of this drive is based on a ballast transistor.
The potentiometer creates the voltage from 0% to 100% of the input voltage and the transistor amplifies the current from the potentiometer (= current which enters the base of T1). You have to use a Darlington.
T1 dissipates the difference of the input and output voltages multiplied by the current flowing through it. If the current motor is a few Watts or more, you absolutely need a heatsink for the drive transistor.
The inverter output voltage is approximately proportional to the input voltage.
