That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an Arduino and has a couple of posts ...

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 use of 555 timers ...

Many applications using ... speed it can be represented by an inductor, resistor and power source. The back EMF, along with the RL circuit in a brushed DC motor, brings non-linearity to the PWM ...

FIGURE 1: Variable frequency drives (VFDs) convert a motor’s ac input to dc to a simulated ac signal at varying frequencies. August 31, 2015 Using variable frequency drives (VFDs) to control the speed ...

A VSD using vector control can control torque as well as speed. Vector control is used to achieve independent control of motor speed and motor torque, similar to how a DC motor is controlled. With ...
