15hp 480 delta at full speed.
Everything to the left of the opamp's is magic signal creation.
Out of the opamp's is the pwm signals that drive the inverter (at a frequency reasonable enough for simulation, but not practical for application)

The t1, t2 and t3 line don't seem to be proper 3 phases

I removed the back EMF (300vdc source) and that cleaned up the voltage waveforms, but now the current waveforms show lock rotor condition. There would have to be a variable ac waveform supply to properly simulate a motor up to speed. Its just to much for this app
