I’ve seen some really high temp magnet wire and with zinc melting at 700f and being a pretty good conductor I’m thinking of giving it a shot. Aluminum melts at 1200f and there’s wire that can sustain that for many hours and maybe even some more standard wire could survive the temp shock of being cast within molten metal. Instead of air encapsulating the heat the vacuumed in metal would transfer better to the stator and if the motor were designed for it could have transit pipes that would go to a heatsink outside the motor.
The cast metal would also hold the wire firm as a winding epoxy does and could replace it.
Maybe there’s expansion rates of the metals that vary and that could lead to failure. Zinc expands more than aluminum and both more than copper. Anyone heard of doing this?https://www.ceramawire.com/technical-information/ceramaTechspec.pdf
I was thinking I’d bring the wound stator up to 700f also with a high temp silicone mold and pour molten aluminum or zinc in and maybe would have to vacuum it in for best results.
Maybe eddy currents would be a problem. Wonder if could be simulated well and tempted just to try it.
