CHANDLER and PRICE printing press power supply and electric motor conversion?

Here is a video of a working electric belt driven printing press. It looks much easier of a conversion than with a capstan drive that will need more precision. I could see the speed being controlled with a VFD (Variable Frequency Drive) or series ac caps or a triac with the size of a motor that will produce the same torque a foot pedal would produce.

for most AC automobiles, you'll want to de-fee the utilized voltage value because that at a decrease utilized frequency the magnetic flux interior the gadget will develop that may develop currents interior the windings. some automobiles are designed for a 50/60Hz variety and paintings superb on both frequencies, yet examine with the motor nameplate or producer. So, for a gadget designed for 60Hz operating on a 50Hz gadget, set the utilized voltage to (50/60)*rated_voltage. OR, there are good-state induction motor drives accessible that may take unmarried section AC at 50Hz and convert that to a variable frequency voltage on the output (i imagine you may variety the voltage value besides). So only regulate the output to 60 Hz. it is a achievable answer, albeit a touch expensive and there'll be some power losses interior the stress.
