We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more appliances which we make use of, are operated by DC. This is a project used to control ...

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, ...

This application note presents BLDC motor control using a sensor sinusoidal PWM modulation with the Z16FMC microcontroller. It further discusses the ways in which to implement the modulation and phase ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector type ...

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 ...
