Kevin,

THis may be a 1725 rpm motor.  If so it can be modified for sync
operation by grinding or filing flats on the armature.   An 1100
rpm motor can also be modified for 1200 rpm sync but will need
6 flats instead of 4.   It's not a very
powerful motor, so the rotor and electrodes should be very light
esp for sync operation, or it won't lock up.
