| (...) I've always been hard on my motors, stalling them often. It's never seem to affect their performance, or even damage them. The difficult part of stalling a geared motor is containing the large forces generated on the structure surrounding the (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

| (...) Yep, and with this one using an 8-tooth gear straight on the rack, even with a solid structure you'd be very likely to break the gear. If you can supply an accurately timed "pulse", that would reduce the risk, but with the geared motors, it (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

| (...) Hmm, Ok. Since it sounds like I'm not risking the motor, and I have lots of 8 tooth gears, I'm going to experiment by leaving the motor on for a while, and seeing what happens. thanks very much for the information, guys! This is exactly the (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

| (...) Well, some good, some bad. The good is that leaving the motor going in one direction for 20 minutes causes no separations and no apparent stress to any parts. The bad is that it did overheat the motor, which wouldn't run again until it cooled (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

| <SNIP> troubleshooting time on this assembly. (...) Will you be posting a new .mpd file to your brickshelf account showing the changes? BTW the othe .mpd file was *not* right. What I mean by that is that usually when one creates a .mpd file the (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

Leaving it on for 20 min- you're boldly going where no Technic-head has gone before... ;-) TJ p.s. I (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)
