I'm working on a 3 phase 20HP motor which its wiring does not match the the name plate.
It does not have the traditional 9 or 12 wires sticking out the side which can be reconfigured for 230v/460v.
Splitting it apart reveals a total of 24 wires, 9 pairs, 1 triple, and L1,L2,L3.
Analyzing the below picture I would assess that L1-3 are in series with other windings which would indicate it is in 460v configuration.
But the triple group would indicate 230v configuration.
Does anyone else have the opinion this does not match the STAR-Y name plate?
Any insight on what this is wired for? (Voltage & Star vs Delta).
My goal is to wire this for 230v.
The plan would be extend the leads out the service port and identify/label them accordingly. (If I can make sense of the 9 or 12 to move out.)
