I decline the role of ex-spurt.

My understanding is that HSD uses magnets buried in the laminations to counter back-EMF that develops toward the top of the rpm range.

I retain this stuff for a short while after reading it. Two big fat wires is DC, three big fat wires is poly-phase DC which is sort of a half-wave AC. Or something.

Sorry.
