Class D audio amplifiers provide a dual benefit for battery-powered portable devices (Figure 1). They enhance battery life, and they produce much less power dissipation than do their linear cousins. Those features make Class D amplifiers ideal candidates for controlling speed and direction in small electric motors. The standard application circuit for a Class D audio […]

The usage of BLDC motor is already increasing due to its efficiency in driving motors with lesser power requirement. It runs with a digital signal controller IC that has processing power of a 32-bit DSP and a functionality of the microcontroller with a flexible set of peripherals. Due this flexibility in configuration, the designed system

Since we now have a beautiful robotic chassis, we’re ready to continue our Building A Robot series, and get serious with some motor control. This second part of building a robot is perhaps the most crucial as it will define what type of control we will have over the motors. Ideally, we want a simple

This is one project that i’m doing, now I’m going to show how to do it only for one motor, but i’m using and DEMUX to in the future use 4 motor. The project is simple, it uses the pic to control the DEMUX and the DEMUX control the H-BRIDGE that control the motor forward
