Controlling Large Motors with Arduino

Hey.

I want to make a microcontroller that can rotate a fan. I don't know how the motors will work with microcontroller.

How can you interface large motors with arduino?

Has anyone have experience working with large motors for arduino?

I don't have any experience with this sort of thing, but you might be able to use power relays.

How can you interface large motors with arduino?

Relays, solid state relays or motor drivers to suit the motor. First, pick a motor to run the fan.

What do you call "large"? For me, a large motor requires a crane to lift the bolts that hold it down to the floor.

Yes, I've seen fan motors that big too. 8)

The first choice for the motor controller is the power source: is it AC or DC?

With a bit more information about your project, I'm sure we can help you.
