Hi. Wondering if someone could help me out with some info on how to change the output of a generator from 60hz to 50hz without a converter? Some advice would be appreciated. Thanks .
A generator frequency cam be changed to 60Hz to 50Hz by changing its speed in rpm. One should remember that frequency ,f PN/120, Hence N120F/P, where N is revoultions per minute and P the number of poles.If you have a frequency meter, run the Diesel engine until the frequency registers only 50 Hz. the voltage registered may be lower than the desired terminal voltage. Here, you adjust the potentiometer trim until the desired voltage at 50Hz is attained. During operation of the unit, if the load is lesser than its rating, the voltage droop at the regulator has to be adjusted ,either increase or lower droop. If your generator is smaller than what I referred to, you will need a frquency meter and AC Voltmeter.
Connect a device that will measure the line frequency whilst the generator is running (digital multimeter) slowly decrease the RPM until 50 Hz is reached. This should be done after the generator has warmed up for about 10 minutes.
The frequency need depends on the application. clocks are a good example because they use the frequency as an internal timer. some devices will operate fine on a close but different freq. same with voltage, most devices know that voltage ranges. Depends on the variance.
The formula for this is f pn/120 f is frequency in Hz p is number of poles (usually 2) n is rpm (rev per Minute)
