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 ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable ...

You can also use a single thyristor, a full-wave unsmoothed supply, and a pot to control the speed. The back-EMF from the motor switches the thyristor off when the voltage drops, the pot setting ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
