However, in this case, the output of the 555 is connected to a MOSFET which is used to vary the speed of a computer fan motor. It’s an excellent way to learn about both PWM motor control and the ...

Brushless DC motors ... The 12 volt output of a standard ATX power supply was used to power the system for testing purposes. A general RC Vehicle electronic speed control and a servo tester ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC ...
