Harmony ClayWorks Posted February 9, 2019 Report Share Posted February 9, 2019 Has anyone found replacement carbon brushes for a Shimpo Bantam wheel. They were made and sold in the US in1977. They have a 200 w, 1/4 hp, 90 VDC motor. A friend bought one 2nd hand. I got the written material for it off the Nidec website (Shimpo’s current manufacturer). It stated about the only thing that canmade it stop is that the carbon brushes wear out and need to be replaced. I emailed Nidec’s chat line, that said they had no parts. If anyone knows of a source or has some laying around let me know. Thanks for your time. Dave Link to comment Share on other sites More sharing options...
liambesaw Posted February 10, 2019 Report Share Posted February 10, 2019 I'm sure they're a stock size, measure the old ones and order more of the same Link to comment Share on other sites More sharing options...
Mark C. Posted February 10, 2019 Report Share Posted February 10, 2019 You could take it to a motor repair place as well.They will order the right brushes. Link to comment Share on other sites More sharing options...
Bill Kielb Posted February 10, 2019 Report Share Posted February 10, 2019 Do the motor repair shop if possible. They will be much more likely to match the carbon / copper content of t(e brushes and will also clean the grooves between the commutator if necessary. One question are the brushes completely worn away? Are we sure it is a brush issue or foot pedal or anything that supplies power to this? Link to comment Share on other sites More sharing options...
Harmony ClayWorks Posted February 10, 2019 Author Report Share Posted February 10, 2019 Thanks for the ideas and feedback. Since we’re no longer a major manufacturing center the motor shops are smaller or gone. Since most of the new manufacturing is micro or nano if motors are involved a 1/4 hp conventional motor is a monster. Thanks again, I’ll keep searching online.

Min Posted February 10, 2019 Report Share Posted February 10, 2019 @Harmony ClayWorks, as previously said look into motor repair shops but also automotive/truck parts shops, brushes are still used in starter motors and alternators. Then there are also repair shops for all the major brands of corded hand tools. I would take one of the brushes out and actually go into some shops. If you walk into the right shop with luck you will find someone who is actually motivated to look through the catalogues/stock room. There are also commercial suppliers where they will cut new brushes from a sheet/strip and install the original leads into the new brushes. If the new set of brushes are slightly too snug they can be lightly and very carefully sanded down to fit. Link to comment Share on other sites More sharing options...
Bill Kielb Posted February 10, 2019 Report Share Posted February 10, 2019 Just a thought, many of these motors are still produced so I think a search on the web will be productive. I still think it wise to at least check the brushes if your friend is comfortable with that to make sure that is the problem. This motor was likely made by a motor company so most often the actual data is on the nameplate for the motor. All things that are fairly easy to pursue. I googled 90v Dc motors and got a whole bunch of hits. one right in Wisconsin that says they repair. I think it’s likely fixable with a little research and effort. best of luck!

Hulk Posted February 11, 2019 Report Share Posted February 11, 2019 Hey Dave, Central Coast Bearing (on Capitolio Way in SLO) might have/get - the owner was very helpful when I needed a cartridge bearing some years ago... Link to comment Share on other sites More sharing options...
