Seeking advice on Makita 2708 motor (tablesaw)
Hi all,
I have bought this saw used, supposed to be working. When inspected I found that the stator was melted so I ordered a new one along with new brushes. The rotor was in perfect condition and all coils are measuring correct impedance. No shorts or damage to the copper connectors. I sanded the carefully and cleaned 'em.
When running the saw I see a lot lightning or sparks from the brushes. Way more than normal sparks, it's like constant blue light.
Any suggestions on what can cause this? Brushed are firmly installed and bearrings are all ok. I've also noticed that the motor motorstop only seems to work in 1 of 50 stops. Don't know if that has anything to do with this..? Thanks for reading!
New coal brushes - they are worn in as they should be, but get's grinded down way too fast
Constant light from the brushes - and no motor stop (supposed to magnetic stopped).
