Motor parameters for MC Workbench: star- or delta-connected ?

Is there an assumption that the motor parameters are for a star connected motor when setting them in the STMC Workbench ?

If your motor is delta-connected, then can you put values given in the motor datasheet directly (winding resistance Rs, inductance Ls and back-emf constant, etc) or do you need to convert them according to the figure ?

No there are not.

If you consider your motor as a black box, Rs is the resistance measured between two phases divided by 2, and same thing for Ls.

More information can be find here.
