Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

This circuit takes advantage of the voltage drop across bridge rectifier diodes to produce a 5-position variable voltage supply to a DC fan or other small DC motor. It is not as efficient as a ...

The circuit illustrates the operation of solid state switches as it controls the movement and the direction of the motor as denoted by the LED. DC Motor – a single coil apparatus used to convert ...
