Before I blow things up...….I'm rebuilding a jig borer to mill capabilities and the motor is a 3/4 HP 3 phase 1400 rpm that I want to use with the VFD.....the problem is there are 6 wires coming out of the side of the motor that are not identified or connected to any terminals so they are an unknown factor.
Testing them with my ohms meter I have found that there are 3 pairs of wires with continuity.....the three phase windings etc.
As I need to connect them in Delta formation, is it possible to connect any three of the sets to any three of the other sets for the delta configuration...... are 3 of the wires the start of the respective winding and the other 3 the end of the winding and can I connect any end/start wire to any other end/start winding wire?
How would you identify the winding starts and ends.....or doesn't it matter with A/C as long as the 3 sets are in Delta?
I'm basically familiar with the configuration of Delta and Star connections etc, but I'm not sure if the ends can be connected to the other 3 ends without being in phase...sketch attached.
