Single phase 60Hz to 50Hz frequency converter can be useful only in domestic or in isolated environments. Anyway, besides limited scope, there are limitations of power. The efficiency is too low for extended uses. Can only be an emergency solution. From the simple capacitor to sophisticated frequency converters performance increase, suitable the price. Technical efficiency in opposition to financial. Are usually more handy three phase power sources. We think by relieving and more researches any impossibility can be possible and that note I consider the theoretically aspect of 50Hz to 60Hz frequency converter example Single Phase to be rectified to DC, the output DC to be converted / inverted to 3-Phase AC.

Normally use GoHz frequency converter to convert 110V 60Hz to 220V 50Hz because of increasing heating of motor.another reason is that it can not prepare sufficient phase difference. it can not be used in the high power. just for temporary and inexpensive starting be ok. but the Method is that;
1. the motor with Star winding it has three output. 2 of phases of Star connect to the one phase and null and the third phase of star with capacitor connected to the frequency converter. the capacity of each capacitor is 50 micro Farad. In Delta winding, capacitor connected to the winding which ground(null) and phase is not connected to the frequency converter..
