PWM (Pulse Width Modulation) is an efficient way to vary the speed and power of electric DC motors. This post shows how to control a PC CD-ROM (or DVD-ROM) drive sensorless BLDC motor using Arduino UNO board and L6234 three phase motor driver. Many a times we need to use MOSFETs configured as high-side and low-side switches. Current that passes through the motor winding is translated into a voltage through the sense resistor. I have spent hundreds of hours on writing code and I have made many minor and four major revisions of the printed circuit board (PCB). As part of my 3D printer project, one of the big electronics hurdles to overcome was a motor controller for a BLDC (BrushLess Direct Current) motor. Basic DC Motor Circuits! Living with the Lab!
