Any idea what type of motor this is (see images) and how to control it?
Here are the images attached to the top post.
Here's a link to instructions how to insert uploaded photos (for next time).
I think the motor looks like a read head out of a video tape machine.
Its a video recorder head motor + rotary transformer + head assembly.
The signals to the spinning read/write heads are coupled to the rotor using a series of concentric
rotatating signal transformers. The motor itself is likely to be brushless, probably 3-phase.
