The motor-speed-control circuit in the figure shows an SG3524 pulse-width-modulation (PWM) IC, U2, driving the high side of a motor through a p-channel FET, Q1. The motor terminal voltage is more ...

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 paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

Brushed DC motors are increasingly being replaced by brushless (BLDC) and stepper motor competitors. But their use still makes sense, as the control effort is considerably lower. Here we show how to ...
