With a copper stator winding there appears to be a direct relationship between electron drift velocity at rotor stall and rotor velocity at no load.
For example doubling the number of turns halves the electron drift velocity at stall and halves the rotor speed with no load. Doubling the voltage doubles the electron drift velocity at stall and doubles the rotor speed with no load. Doubling or halving the winding cross section doesn’t change the electron drift velocity at stall and doesn’t change the rotor speed with no load.
Changing the winding material from copper to silver (without changing the geometry) changes the electron drift velocity at rotor stall, but does it change the rotor velocity with no load?
