We have machines with total driving power of around 150Amp. Our machines are 3 phase 50Hz and have been moved to 60Hz working area. We need a frequency converter to covert the frequency from 60Hz to 50Hz so as to operate the machines properly.

The power line supplying our factory is 150Amp. From this line we supply the individual woodworking machines we operate. These machines have a power of 5 - 7.5HP (3.5- around 5KW). The number of machines we have is around 15 machines. The motors of these machines are 50Hz/ 3phase/ 380V. The power in our new location in the country we moved to is 60Hz/ 3phase/ 230V.
We can have one or more than one converter for the machines according to the converters we find most suitable.
But we prefer to have less number of frequency converters as too many converters will get in the way of the work. Therefore, we prefer to hook more than one machine to one converter. We don't know how many we can connect to each converter and this depends on the converters you manufacture. Ideally, we prefer to have 1 or 2 converters if we can.
I hope I explained our environment and needs. is it the frequency converter suitable for this and for what process?
