Did you consider using another base plate and another bearing so that you can have a 2 point shaft support? You can then use self-centering axial-radial bearing at one side to compensate for eventual lateral movements. I have had experience building powerful motor from scratch and one point support of shaft is simply too unreliable for the forces involved. Especially with pulse motors.
Nevertheless - a GREAT work pal!  |
if you check the commutator side you can see that he does have two bearings on there, still I think you may be right adding another bearing, but i would place it on top, where there is none at the moment. Or is that what you actually meant?
Also I doubt whether all the noise is coming from the bearings. Tweaking the timing a little bit might also decrease noise.
