| | | That figure was the normal operation (no load) figure. What concerned me was that it was a factor of almost 20 higher than the gear motors which normally run about 10mA. Of course, it is very easy to overlook the fact that the gear motor is (...) (22 years ago, 8-Jan-03, to lugnet.technic, lugnet.robotics)

| | | | Ok, here is an extrapolated result for the short circuit (stalled) test. The current at 9 volts would be 3.6 amps. Since I did not wish to burn up the motor, I checked current readings at both 3 and 6 volts and also measured the DC resistance and (...) (22 years ago, 8-Jan-03, to lugnet.technic, lugnet.robotics)
