Invisible ? No idea what you mean here . Anyway , the simple fact is that the last rotor project you send to the list had a built- in spin attached to the rotor . Set that spin to 0,0,0 and the machine no longer ran . > I quit in frustration for a while and came back to it this morning to check > the Inertia .... if you set Inertia to 0 0 0 and with stators invisible ... > there is no spinning.

Yes , the Rotor stays at rest even though you have a magnetic field situation set up . This machine will sit there and do noth- ing unless you add the .001 inertia to it . > I set the rotors and stators to +.2 and -.2 and the inertia of the Rotor to > 0 0 .001 ..... then it works as desired with the Phys/spin and velocity at 0 > 0 0.

Well I ran this attached file (first increased the frame amounts to 3500) and it would just roll back and forth ... back and forth ... for 3500 frames . Is this what you mean by "running" ? Perhaps I'm mistaken in assuming that you were trying to get the rotor to spin the way it did in your last project file ?
