Hi all,

Am trying to control a EBM papst fan motor which has following spec;,

input voltage : 230V
control voltage : 0-10Vdc or PWM

is it possible to control the above fan motor using arduino?
If so, can you please explain me how to do so? ( How to generate 0-10Vdc control signal from arduino)

You need a 10V power supply, an NPN transistor and two 1K resistors.
Transistor is wired,
Emitter to ground, base through a 1K to a PWM able output pin.
Collector to a resistor, other end to the 10V. Then connect the input of your controller to the collector of the transistor, and make sure all grounds are connected together, that is Arduino, controller and 10V power supply.
