jay Posted January 21, 2014 Report Share Posted January 21, 2014 My older 18 v power plus has a burned smell when I turn it on. Would changing the brushes remedie the situation ? I took it apart but don't know where the brushes are hidden... Quote Link to comment Share on other sites More sharing options...

jay Posted January 21, 2014 Author Report Share Posted January 21, 2014 What brand and model is that? Milwaukee power plus/ made in germany...the model # wore off the sticker. It about 15 years old.. Quote Link to comment Share on other sites More sharing options...
Brien Posted January 21, 2014 Report Share Posted January 21, 2014 I doesn't look like your model is serviceable. The brushes are internal to that motor. You would have to pry it open to get to the brushes. Anybody else know better? Quote Link to comment Share on other sites More sharing options...
Kato Posted January 21, 2014 Report Share Posted January 21, 2014 You're correct. This type of motor has small electrical contacts, not brushes, that run the motor. Same concept as brushes, contact is made, which causes wear due to friction, dirt, etc.. Unless you have the right knowledge and tools, when the motor dies it's garbage. Try shooting electrical contact cleaner inside the contact area, then run the motor. Might clear up the smell, and might "rejuvenate" the motor a bit to help it run better. Does the drill run, and just stinks, or is it dead? This is one problem with terminology.Everyone is talking "brushless" these days, which isn't a new concept, just a new design. Motors like the one you have are brushless, the contacts are electrical contacts and not brushes (technically they're brushes, but designed differently). "Brushless" tech now is completely different, it's totally void of contacts, brushes, etc.. The motor spins due to electrical and magnetic impulse, no friction from brushes or contacts.

jay Posted January 21, 2014 Author Report Share Posted January 21, 2014 Drill still runs, it just smells . Torque seems to be ok.. Quote Link to comment Share on other sites More sharing options...
Kato Posted January 21, 2014 Report Share Posted January 21, 2014 Spray contact cleaner inside the motor, then hit the trigger a couple of times to run the motor. Could just need a good cleaning Quote Link to comment Share on other sites More sharing options...
