I had an idea recently on vacation to replace the cogged wheel on the 3D printed televisor im making with a stepper motor, but while still keeping the universal motor to provide most of the torque. I have noticed that with some of the stepper motors i have bought, they are exceptionally high in torque while turned on. By high, i mean needing two of my arms and a foot long pole connected to the axis to act as a lever, and i still had trouble! You can by stepper motors with 2,4,6,8,10,12,14,15,16,18,20, and up to fifty poles, but after a point they become un-affordable. So the basic concept would be to have a sync signal from the video signal converted to be able to power up the stepper motor, and wait for the universal motor to come up to speed. The stepper motor would not be powered up all the way, so as not to retard the speed of the disc. So far, its an idea and a hastily explained one at best, but still needs to be tested and have some designing done.
Fun times, ain't it?
