old motor connection supply with 380v,Now i have 220v ,3phase,who i will connect the motor to operaate in agood mode.
If you mean the motor was originally wired 480v 3 phase and you want to wire it 220v 3 phase, it is possible with some motors, you can tell by how many leads the motor has. It needs to have 9 or 12 leads to be able to be able to run on different voltages. The motor should have a nameplate that tells you if it can and how to wire it. If you don't have directions on the motor here is a link that explains it well. Be careful!
