Figure 46 Parameter variation during 75 hp motor start
The effect of including mutual flux path saturation in the modified motor model is minimal.
This is shown in Fig 47, which plots of the speed during a 50 hp motor start for the case of
including the mutual flux path saturation and omitting the mutual flux path saturation in the
