The problem with simulations is that you are trying to simulate a dynamic system with static parameters, and you don't even have all of the parameters that are effecting the system, such as: permeability and conductivity and distance to all materials in the motor.
You also don't know how well the motor can cool itself and how the various materials react with heat when given multiple kW...
Sim's also don't account for loss of motor force due to coil leaving the gap. You'd have to know the coil height and gap height, at a minimum.
If you want a truly accurate model, you have to quantify those, and apply the related math to the model. t/s isn't enough information!
The math that reality uses is fully-complete and all-encompassing, the math humans use is far incomplete.
Reality has no problem calculating the effects of your pet goat ramming your dust cap in the middle of a sweep or the effects of the lightning blast in your backyard, the software didn't account for that at-all...
I love how scientists make generalizations and simplifications in their models, and then wonder why it doesn't match reality.
Throughout grade school you were taught to neglect air resistance. Air resistance is very-real and non-neglectable. Among others... LOL
You can't model the universe if you don't even know where an electron "is" or if it is a "wave or a particle" or both at different times, based on observations or the lack thereof. LOL!
3-body insolvability problem, and the other unsolvable math\universe paradoxes etc etc etc... LOL!
