I have shot a bunch of compressed air in, but not 100% sure I’m directing it to the right place. The debris still seems to be there, though it does seem to move around, so maybe that suggests magnetic debris.
I’m in the process of disassembling the motor and it’s great to see someone’s done it before! After removing the two caps (front and back), I was planning on using a gear puller to separate the rotor from the stator – did you do it with something less drastic?. It looks like you left the cap on the stator (I see the bottoms of the 4 screws in the first picture) – seems like I should do that too?
Did your insulation get scraped off from that winding in the second picture?
I’m honored to get your response; I’ve been doing a bunch of your mods as this is a batch 1 I think, and the mods are awesome – thanks for documenting them all!
