Run A CDROM Brushless Motor With Arduino : Run A CDROM Brushless Motor With Arduino A brushless dc motor or BLDC is a type of motor without any brush. I think it is a proper low voltage motor for our project. It means that we should prep.A brushless dc motor or BLDC is a type of motor without any brush. It means that there is no direct connection (brush) between rotating spindle and other fixed parts like as coil. So the spinning is yield of changes in current direction of coil.The spindle has a circular magnet (usually). And the coil is an electric controlled magnet itself. So by changing the poles of coil, you can turn the spindle.Have you ever seen a BLDC? Yes, of course. There are many of them in every computer case.Fan, CDROM and also Floppy drive (if you have yet) are devices that use BLDC. The fans usually use 2 phase motors with 2 pins for coil and 1 pin for Hall sensor.CDROM or Floppy drive has 3 phase motor, with 3 pins for coil and 1 pin for Hall sensor.The mentioned Hall, is a simple sensor to detect the current magnet pole of the spindle. Whenever a magnet reaches, it generates a signal. So you can use this pin to detect rounds of motor and also you can control the motor speed (RPM) by altering the signal speed according to this pin.I thinks it s enough of theory, let s make!As you can see in the photo, I found a SAMSUNG brushless motor in my old ASUS CDROM. I think it is a Moncler Down Coats Men Hooded Mid-Length Silver proper low voltage motor for our project.I have many old Hard disks in my room but they are a little bit hard to disassemble and depart. So for this beginner guide, the CDROMs are better victims.Anyway, as mentioned before, we have 4 pins to soldering a wire. It is easy to detect the coil pins, they are after each other. Usually last pin is sensor.But if you had any problem detecting pins, connect a (+), ( ) 3 volt to them to see the spindle shake.Firstly, Moncler 2012 Women 0018 3 phase motors (which BLDC is) should have wires named U, V, W. Just for proffesionality. And so are named on your motor board, just look a bit under the motor.Secondly, This method of driving isn t goot, because when one Moncler Cheap Jackets winding is high, other is low, last winding should be in high impedance state just not connected anywhere. In your method you have one winding high, and two low. To achieve correct BLDC driving you should use two L239D chips, to have at least 3 separate Enable pins, to be able to put one winding in HiZ when the other ones are connected.
