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 DC motor speed control project is intended to manage the pace of a DC motor by means of an 8051 sequence micro-controller. The pace of DC motor is straightforwardly relative to the voltage ...

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

That’s basically everything except speed control of the motors. There are so many ways to control the speed of DC motors, but an easy way is to use pulse-width modulation. Here, applying a PWM signal ...

The DC motor speed can be controlled from 0 rpm up to 150,000 rpm. ... This DC servo motor controller can also be used with an external potentiometer or the integrated on board potentiometer.

Speed control: There are two ways to adjust the speed of a wound-field dc motor. Combinations of the two are sometimes used. Shunt-field control: Reel drives require this kind of control.
