Op amps are like the great unknown to me. I got used to them a little bit on a project I did, but I know almost nothing about them, and the tricks involved in getting them to behave. I only did math in school, and they skipped op amps in my math classes. haha.

I just ordered 2 LEM Hass 50-s current sensors for testing the motor outside. I also found out that the control technique for GRID TIE (3 phase) is identical to standard field oriented control with a synchronous motor. The grid is a motor in either regen or "not regen" state.

I need to solder those dang control boards tonight.
