An H-bridge (full-bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-bridge driver are high ...

This project controls the speed and direction of a DC motor using an Arduino, a potentiometer, and two push buttons. It requires an L293D motor driver IC to function ...

In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

ArduinoでDCモーターの回転をPWM制御で行うところまではできた。 問題は、実際のターンテーブルが、できるだけ正確に、そして安定して33.3回転を回ってくれる事が大事である。 ところが、実際に回してみると、どこかで回転のロスが出ているのか、抵抗が不 ...

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, ...

この「速度制御」を実現する鍵が、サーボモーターの角度制御でも登場した**PWM（パルス幅変調）**です。 今回は、同じPWMという技術を使い、DCモーターの回転数を自在に変えるための基本的な考え方と、Pythonでの実装方法を解説します。

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
