But it is a trivial matter to run any three-pahse
motor from
single phase... one uses capacitors to shift the phases of the
windings in proper relationship. It takes a knowledge of R/C
networks and a good AC ammeter to finely balance the currents in the
leads, but it can be done for the price of the caps. If one has
access to a large surplus or appliance salvage yard, so much the
better. I have run several machines this way.
Have you actually run a 9766 or another comparable drive that way?
Everybody talks about doing it, but I've never yet heard any documented
case of it being done for a removable-pack disk drive using an AC
synchronous spindle motor.
I'll believe it when there's a documented case of it being done, and
working successfully. Until then, I'll stand by my claim.
