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 ...

This application note presents BLDC motor control using sensor sinusoidal PWM modulation with Z32F128 microcontroller. It also discusses ways on how to implement sinusoidal PWM modulation and ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...

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, ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.
