Hello Tom, I also cannibalized such a washing machine motor from a junk machine, with multi vee belt pulley etc. as described. It has brushes and separately accessible field coil terminals. This brings me to the conclusion that the motor is simply run with different field voltages to yield slow and fast movement like in the good, old DC times - no three phase motor, no variable frequency devices, but usable... :-(
