Hello,
I have a CD drive disk brushless motor, and I want to build a simple anemometer using it. I detached the motor, it is built-on a small board containing 3 electronic components (H1, H2, H3) I think these are Hall-effect sensors... I don't know much about Hall-effect..etc and this is not the point of my question. I can see three wires come out from the coils of the motor. What I know about these motors is that they are BLDC (brushless dc motor), so they are DC. I want to know how to power it, if it needs a control circuit I'll be very thankful if someone provide me with a simple circuit, and notice that this motor have 9 coils and only 3 input lines to it. By the way this is not for the anemometer project. Back to the anemometer and the cd drive motor, I want to get out a DC voltage out of it, using a rectifier circuit (I don't know how to do it in this case -3 lines)
Here is the project that I'm trying to build: http://www.instructables.com/id/Easter-Egg-Anemometer-Wind-Speed-Meter/
In this one, the motor seems to be a normal brushed dc motor.
Regards,
Hazim
