I have a 1946 Leblond Lathe with a 3 phase motor. The wiring on the motor does not have the newer color codes to indicate L1, L2, and L3. On this motor all 3 are black.
Before I start adding external switches etc to tie into the VFD, I would like to get it up and running just the VFD to make sure the motor is still good. In my understanding of 3 phase, I should be able to just hook up the 3 wires to T1, T2, T3 and it doesn't really matter on the order. Worst case is that the motor might run backwards instead of forwards, and if so I would just swap 2 of the wires.
Is my understanding correct?
