3-phase Induction motor (solver)
To test the motor I have created a three phase voltage source. I have troubleshooted the model and have figured out that when running a simple sine wave I can reset the step size for 60 hertz frequency to .001 and it follows the signal correctly for 5 seconds. The only problem is if the simulation time is longer than 5... 12 Jan 2010 16:18
