The document was unreadable, because it didn't download.

The short answer is, NO. The other poster has pointed you to a microcontroller that can be used to drive the 3-phase motor. It will not be a simple task to run the motor from the CD ROM. There is no way to apply simple DC and have it run.

Hook wires to your battery, and touch them briefly to the motor terminals in every possible combination. Some of these might work, and if so you can see which is best.

However, I don't know if a CD-ROM motor is powerful enough to run a propeller.
