Why do my simulation results not match the nameplate results of my Induction motor?

      I am trying to create a model for my induction motor and I have taken all the measurements of the machine and the winding configurations but I still do not achieve the expected results on the name plate. I am running the simulation in Wye connection and I will attach a picture of the name plate of the machine I wish to model as well as the machine motorcad Model I have created. I am hoping that there is a calibration of sorts that will allow my model and physical motor to match in results. If anyone has any Ideas please let me know.

      Hello Qiuncy For this induction motor, there is "230/460 Volt" in the nameplate, and it means line to line voltage is 230/460V rms. However, 230V is for the phase voltage in the model. The frequency is a little bit smaller than 60Hz and we want to reach 60Hz for this operation, please use speed/frequency in "operating point definition".
      Do you know and have as-built winding pattern and turn for this motor ? Do you know exact stacking length and slot shapes ? if not, you may have to try many arrangements to achieve phase current and specification of the nameplate.

      I'm running DPM simulations and would like to use turbulent dispersion ( 16.2.2. Turbulent Dispersion of Particles ). I'm not sure if I need to adjust the time scale constant (C L=0.15) if I'm using a k-omega model. The theory states that epsilon=0.09*k*omega must be substituted in the expression T L C L*k/epsilon, which I do not understand since C L should be universal.
