TECHNICALLY POSSIBLE .
BUT YOU HAVE NOT MENTIONED WHETHER IT IS SALIENT POLE OR NON SALIENT POLE CONSTRUCTION. IT IS QUESTION OF DESIGN ASPECTS OF EXISTIG MOTOR VIS A VIS NEW OUTPUT REQUIRED ALONG WITH OTHER PARAMETERS LIKE TORQUE(NORMAL) AND PULLOUT AND STARTING TORQUE REQUIRED
K.S.RAGHAVAN...
the d.c votage vs ac voltage depends on the number of phases and type of connection ie.,halfwave and full wave
Ripple factor again governs the final dc voltage
sixpulse rectifier can give a higher dc voltage than its rms value if it is with proper ripple factor correction and these basic data...
What will be the performance of microwave oven plugged into 240V, 50Hz circuit instead of 60HZ circuit when the original design is for 60 HZ at 110V
of course voltage can be transformed with a suitable transformer K.S.RAGHAVAN
