How are the position at t=0 and gamma defined in Flux, and how is end winding impedance calculated?
Hi I am following the example "Flux - Twin Activate Coupling: IPM Motor Speed Control", focusing on Case 3, where the initial rotor position at t=0t = 0t=0 is set to 7.5°. I understand this is determined as the zero-crossing point of the phase-one voltage through back EMF analysis, as explained in the example "Brushless…

Flux cannot display ISO values - gives error
I have a 3D AC Flux model. Solving does not produce any errors. But trying to display iso values fails with below error. What are possible things I have done wrong? OCRI04 => Number RB.F3D.REG_VOL(0) out of bounds OCRI04 => Retrieval of INTEGER attribute aborted RVRTY3_1 => Failed RGR2SU => Retrieval aborted RGR1SU =>…
