How To Make Simple DC Motor Speed Controller Circuit
Building an electronic circuit for achieving DC motor speed control may seem quite simple, and you should be able to find many such ordinary circuits dealing with speed regulation.
However, practically you will find that simpler circuits have one serious drawback – they are not able to control the motor speed smoothly at lower levels, and as the desired speed is decreased, the torque of the motor also decreases proportionately.
Due to this, at any unpredictable point the motor may just halt very abruptly.
Also, during power ON, the motor may just not start up at lower speed settings and may require an initial boost by increasing the setting. Such situations are pretty undesirable and do not constitute an ideal speed control.
