internal connections for 3 phase motors.
(OP)
ran into a problem last week trying to reconnect a 2 delta, 575v 3 phase motor to 4 wye 480v. does anyone know where i might obtain some internal winding connection diagrams for 3 phase "concentric" wound motors. have all the lap winding connections, but am lost when it come to concentric windings.

Take one of the delta's and label them 1 to 12. Do the same with the other.
Your leads should be 1,2,3,10.11 & 12.
Jumpers are 4 & 7, 5 & 8 and 6 &9.

...12 groups 24 ends...? Aaaagghh! Please pardon my outburst. My head just exploded.
