Ok so there are many posts about how to wire a 3 phase motor one way or the other. However one topic I cannot seem to find any information on, is if you have the choice between running the motor at 380V on a Y wiring setup, or using 240V with delta setup, does either option make the motor perform any differently, in terms of useable power/torque when using the lathe? I ask because I need to upgrade my VFD, I have found it keeps cutting out from getting too hot. The motor is a 6 pole 1.1kW motor, but the VFD is rated only 0.75kW for constant torque applications. I like to turn large bowls, so often find myself using the VFD at low RPM settings for extended periods.
Currently the motor is set to delta wiring for the 240V VFD. Would there by an advantage to look out for a 380V (output) VFD and change the wiring to Y setup? As its an extra cost to get a VFD that produces the higher voltage. Just curios whether I would notice any difference.
