This wonderful & powerful motor was harvested from a laser printer. It is a brushless 3-phase DC motor with control board attached to it. The control is made by LB11923 and 3 power transistors one for each motor coil.
I post here the image asking if there is a way to hook this board/motor to Arduino ? how a simple code would look like ? any idea ?
this is the IC datasheet
If you want to hook the board to an Arduino, then you need the data sheet or equivalent for the board!!!!!

Have you tried Google to find the service manual for the Laser Printer?
Sounds totally possible - assuming the descriptions of the connections are directly connecting to the respective pins of the LB11923 driver chip.
You have the datasheet of that chip, a quick glance of the specs (and confirmed by the +5V marking) tells me that this operates at 5V supply & signals, making it at least electrically compatible with the Arduino.
The CLOCK pin is probably for the speed control; the CW/CCW pin is likely for the direction control (apparently unused in your specific printer but it's broken out so you may be able to use it). The READY and START no idea what it should be, maybe you can find more clues on that by studying the LB11923 datasheet.
Absolutely no idea what the code for this would look like. You may look into is the AccelStepper library: yes, it's designed for steppers, but those also use pulses for speed control just like this driver appears to do.

The connector is handily marked with all the signals - its a step+direction interface (CLOCK and CW/CCW) so AccelStepper library can probably drive this direct - you'll have to figure out START and READY meanings.
