I have been looking back at some old robots from past years, as this years game has some aspects that are “blasts from the past.” I have seen some robots from starstruck employing an amazing RD4B running on 2-4 393 motors, but Im not sure if they are a 1:1 facsimile of modern motors or if they are w…

Some speed-torque curves in this old topic [image] Motor torque-speed curves - REV2 Technical Discussion Back in May I had posted the theoretical speed-torque curves for the 393 and 269 motors. Other forum members did experiments and IFI confirmed that the curves matched …

The 393 motor was named that way because the power at design stage was 3.93W. Same for the 269 motor (2.69W)
