Probably the wrong forum but learned that many members are not only good in software, i try this thread.
Building a mill with 3 x 750 W 230 Volt ethercat drives with a power grid [ 3 x 230 volt or 3 x 400 volt/ star triangle
When comparing 1 phase powered servo drives to 3 phase powered servo drives the DC voltage is at one phase motors a little bit noisier.
You could connect all three motors to one phase or every motor to a different phase when having 3 phase power from the net.
What could be the difference on machine performance in the case of situation with one phase compared to the situation with three phases on the noisiness?
The power grid would like the situation with every motor on a different phase but does it produce noise with a higher frequency?
