Following from our previous article about the home-made three phase electric motor, we have now a new three-part (or phase?) tutorial on how to drive three-phase brushless spindle motors that are found in old CD/DVD drives. The authors have described more than one method of doing so, and also explain how to use a SN754410NE motor driver IC as well. Finally after several demonstrations the tutorials culminate with the design of a stroboscope - a rotary form of animation shown below:
