This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

The Arduino sketch reads the data from the potentiometers and sends the cursor position and switch clicks to your computer through the USB cable.

It envisages applications in motor control, load management and switch-mode power supplies. A89347 is the fan driver IC, also qualified to AEC-Q100 for automotive use, and proposed for electric ...
