http://homepages.enterprise.net/jayjay/cdrom_motors.htm [Broken] So this is modified brushless motor. It says that it uses jeti06 ESC. But frankly I am not ready to sneeze 25€ for a ESC. How do you drive this in principle? You send pulses into those 3 windings, one after another, something like a synch machine? Can somebody give me an explanation what is happening, in a nutshell? I will chase the math later, I need the idea how it works.
