The phases on the AC output connector are rotated to balance the load on all three phases when three drives are daisy-chained. If you look at the power wiring diagram on page 3-120 of the Memorex 677-01 manual you will see only two of the phases going to the power transformer.

Ok.  I just looked up the RP04 maintenance manual.  It isn't all that explicit but it does say that the spindle motor is a 3-phase induction motor.
