I did experiment with that idea. It's terribly wasteful of magnet, though, a lot of flux is inevitably short circuited.circuit said:I'm wondering how you are going to keep the magnets from flying away. Would not it be better to simply embed the magnets under the surface of rotor's lamination? Should not be hard to do in this configurarion.
Miles said:I haven't got any quotes for laminations yet. I'd guess a one off .35mm C5 lamination stator/rotor set would be somewhere between $150 and $200? To get things cheaper, you'd need to have them stamped in large quantity.
Let's try this out as a prototype, first. If it's any good, I'll think about putting a kit together for people to make their own.
Jeremy Harris said:That configuration is great for bonding, as adhesives are generally far better in shear than they are in tension. I suspect the bond areas on the small locating upstands will be more than enough to hold the magnets against the modest centripetal force, and the adhesive overall stress levels will be lowered by not having to take any of the shear reaction from torque.
