415 Volt 50 Hz Supply
415 Volt 50 Hz Supply
(OP)
We have a small air compressor (1/2HP) 120 volt 1 phase 60 Hz.(Capacitor start) Motor is single voltage and frequency. A customer of ours wants to use this overseas where the available power is 415 volt 50 Hz. Without derating the motor what is the best and most economical way to convert the 415/1/50 to 120/1/60? Thanks!





RE: 415 Volt 50 Hz Supply
An alternative is to get a 415-120V transformer and go ahead and run the compressor at 50Hz. It will run at 5/6 speed which for a compressor will translate into taking longer to reach the pressure setting in your tank. It may pull more current under the same load as well, so it will run hotter and die a premature death. Then just replace the motor with a 50Hz unit of equal power. It may take years for the extra heat to damage the motor anyway.
