Data explorer reports the angular velocity at 60Hz as 37.6 rad/s not 60*2*pi (377).
see example ee_loadflow_sm_initialization.

Hello Ralph,
the number of pole pairs for this machine is 10. You are seeing mechanical angular velocity, which is generating an electrical frequency 10 times that due to the pole pairs.

Joel
