My idea was that a multi-phase coil system would be faster than a single-phase design that seems to be standard among commercial manufacturers. It would complicate the driver a lot though. But what the heck. I'm a electronics engineer - I live for this kind of thingsI found the attached picture in somewhere this forum and I think that galvo looks very much like a two phase design... I think they where made by scanergy.
By the way. I have almost figured out the perfect designWater cooling and heat conducting ceramics. No electrically conductive materials anywhere near the moving magnet. I have even figured out how to make a flux ring to boost the magnetic field strength without creating any eddy currents. I really need to try this. I let you all know how it went in a few years when I have found the time to try these ideas
