So it's easier for me to provide a positive contribution - I'll dare again
Google'ing the coercivity of Nd Magnets yields somewhere between 600 and 1200 kA/m.
For Sa-Co I found values as low as 80 kA/m
Whats our field?
can still only speculate.
I remember a figure of some forty windings for a custom make, so 50 might be a reasonable order of magnitude.
People (larsb?) have reported 500 phase amps.
And we need some geometry factor (coil length?), for which I'd throw up 50 mm
200 A - 50 turns / 0,05m = 500 kA/m
So we are in the magnitude of Nd coercivity, and taking inhomogenous flux intoaccount, i still see a risk.
Loooks like I did'nt manage to shift the borderline of speculation that far
But as i've got it, reluctance torque and field weakening are different concepts?
Maybe both are utilized by the same sihft of current phase angle, but a motor w/o reluctance can still use field weakening - OK?
The rotor image here
shows nearly no gap between magnets, which I have learned were relevant for reluctance torque, OK?
Anyway, I'll not dig into all details of motor design.
I just would like to program my controller so that I can get out the torque curve QS labelled "with flux weakening" in their ads .
Unfortunately, the Votol controller figures are not comprehensible in terms of physical meaning - at least not for me.
The best point to start with I found is this file
