It looks like you just subtract off like 20% of a period, but I think I remember someone saying that it's actually 90 degrees offset, so maybe my sensored rotor flux angle is off by a few %?
Is it time for me to couple the DC motor to the AC motor again?

I have a hand-held tachometer to check rpm, and you know what rpm the motor is turning .. so we should not overspeed the DC motor .. right?
