Old DVD drive motors revisited

Old DVD drive motors revisited. There is a discussion thread running on one of my old videos regarding the stepper motors I had taken from an old CD/DVD drive. To give some extra detail I had a look in my junk box and found another drive assembly and now we have some close up detail to view. You could probably equate these to in-runner and out-runner brushless motors when you look inside. I have also done a short extra video because I also found a drive assembly which has a normal brushed DC motor so we can see the difference https://youtu.be/yMTEmK6P6BU. The original video being discussed is here - Things you can make from an old DVD drive #2 - Step a stepper motor https://youtu.be/kRSwakr8hsw
