I have an old European Electric Synchronous Motor Clock that is running at 110 Volts at 50 Hz with no earth ground or fuse. I have grounded this clock and fused it. However, this clock is running fast since it is running at 60 Hz and the clock movement was designed for 50 Hz. I am going to convert this clock to run at 16 volts AC to make it safer by creating a new coil with the appropriate turns to have this motor run at this voltage. I will then purchase an UL approved 16 volt AC power pack. I will still have the problem with the frequency since this clock is designed to run at 50Hz. I am looking for a way to make this 50 Hz clock useable at 60 Hz using my 16 volt AC Power pack as the power supply. I do not specialize in electronics and only have a digital volt meter and a variac. Any help on this would be greatly appreciated.
