Quadruple Rated 3ph Motors
Quadruple Rated 3ph Motors
(OP)
Is there any standards or conventions for external wiring of quadruple rated three phase motors with 9 leads?
It is about one voltage multi mode winding connected in four ways ( delta, wye, combined delta-wye etc) in order to get four different values of torque.

RE: Quadruple Rated 3ph Motors
The electric motors leads most be marked according to NEMA Stds. MG 1 or IEC 60034-8 wichever is applicable. In case of multi mode winding connections the motor manufacturer will mark the leads according to the place of the world where be manufactured or according to the place where the motor will be installed and most provide a nameplate( plate or print) indicating correct connections.

That wiring I already have.
Attached photo shows a little different wiring (transcribed from the plate of the 6 pole GE motor).
Does anyone know more about it?

Yes you are right, the leads 4,5 and 6 are not center taps, please see attached diagram for 6 pole 1 circuit.
