bml3e4crk brushless motor is commonly used as the spindle motor of many CD ROMs. Can anybody find the pinout to the 11 pin connector of that particular motor. Because it can easily be used in another project

If it is not directly available on the internet, you need experiment to find the pins. If you know the theory of BLDC motors, it is not a big deal. More than half of those pins are for sensor feeedback so you can omit them for now.
I have found a PDF with pin outs of another 3-phase BLDC motor. Hope this will give you an idea.
