9v system Posted October 15, 2015 Posted October 15, 2015 hi all I have tried two time to get a dead micro motor back to life and so far I have been able to get them working but then I try do get rid of the magnetic powder and that kills the motor when I try to put power through it. has anyone been able to successfully get them working again without having to take them apart again? if so can you tell me how you did it? thanks 9v system Quote
1974 Posted October 15, 2015 Posted October 15, 2015 They're very difficult to work on, but I have fixed a few. Mostly just for the sport of it as the time it takes is definitely not worth it As long as you never stall them WITHOUT the pulley or overvoltage them, the do not seem to go bad, despite what you can read online. I had more than a hundred go through my hands I haven't killed one yet You might find this interesting : http://mindstorms.itgo.com/micro.htm Cheers, Ole Quote
allanp Posted October 15, 2015 Posted October 15, 2015 I fixed one by dropping it onto a hard tiled floor . I think it must have unjammed some gears. Quote
1974 Posted October 15, 2015 Posted October 15, 2015 Funny, this also how I fix my computer, tv, food, car, gf, my life and the entire world Stuck gears with these motors happen if you DON'T use the pulley (which has a build in clutch mechanisem), so if it's stuck do the "allanp", it might do the trick! Do that before you open it up, because once you've opened it up, it'll take a proper ninja to put it back together Cheers, Ole Quote
allanp Posted October 15, 2015 Posted October 15, 2015 Well they should not have made it fit perfectly into a technic hole then should they! Quote
1974 Posted October 15, 2015 Posted October 15, 2015 Hmm, not sure what you mean by that! They may "fit" into a technic hole, yes, but once you've got them braced up and cabled, they do take a bit more space. Proper motors works much better, imho And oddly enough, I got 30 mms for sale at BL So how about it "9v system", what is the actual state of your mm? Cheers, Ole Quote

CP5670 Posted October 16, 2015 Posted October 16, 2015 (edited) I've had them stop working after just being left in a model for a few months, when they were previously working fine. It seems like the gears get jammed, since if I hold them up to my ear and start them I can hear a very faint click. I've tried dropping/throwing/shaking them but it didn't work. At this point I don't bother trying to fix them and just use them as decoration. They make good minifig-scale generators on buildings. Edited October 16, 2015 by CP5670 Quote
Captainowie Posted October 16, 2015 Posted October 16, 2015 What is the benefit of MM's anyways? They're very small, and they're very light. And apparently they make good minifig-scale generators. I've seen one used to very good effect making a dynamic brick-badge at a convention. Owen. Quote
