BLDC Spice model?

I'd expect it to be the same as a regular PM DC motor: windings commutation is just not done with brushes but otherwise I can't see any difference.

Anyone have a decent Spice model for a BLDC motor?

I see a bunch of IEEE papers and some commercial products on the net, but nothing freely available.

Thanks!

I'd like to be able to model, for example, the difference in torque ripple for sinusoidal vs. trapezoidal commutation, and accurately model the waveforms at the driving semiconductors. I don't think a DC motor model will work for that.

If it's never been done, might you have to *GASP* _MEASURE_ one? ;-)
