Cool little motor Angus.
"I was planning to just turn it down, epoxy the magnets on"
That's what I do.
The intention is to keep the factory coils?
About what size is the coil wire?
How many ohms per phase or set of coils?
My guess, do not turn it down for 2 magnets deep. Looks like it will fall apart.
That's a 220V motor? The coil resistance is probably pretty high.
And the coil wire pretty small.
Might be OK because it has 6 wires. Wish I could find one like that.
Keep the magnets close together. The flux can be shorted out, back to the rotor, with a piece of malleable steel for each magnet. It lets the next neo be placed a little closer to the last one. I could post a sketch if you don't follow that.
Careful not to epoxy the steel to the top of a neo. :-(
It's easier for me to epoxy 1 magnet per pole, per day. Use slow cure epoxy, not `5 minute' epoxy.
Looks like it will be a high voltage, low amp PMA.
That kind of blades sure don't go very fast. I think they sort of self-stall. Hub can be good for wood blades.
Be gentle handling it when the coils are exposed.
Big fun!
