	No,but you can run the machine by connecting a Ac drive. By connecting your 60 HZ M/C you can run but not at full speed. you will get only the M/c rated speed/60 X50. __________________ Binod Kumar Panda

	Friend, syn machine has been designed in order to get maximum benifits at minimum maintenance. But I do not recommend for this. Do you remember this formula: N=120*f/P Where N= speed in rpm f= frequency P= No. of poles So for 4Poles at f=50Hz, N=1500rpm; similarly for 4Poles at f=60Hz, N=1800rpm. Hence, we need to run this machine at high speed, the probable problems occurs are: 1. Vibration 2. Failure of bearing 3. more forces over over hangs of rotor. 4. Probable chances of rubbing between rotor and stator. I feel I have answered your question. Suvek Kumar __________________ Er. Suvek Kumar
