If anyone in here is motor savvy...
I have 2 motors, 0.6hp, 3 phase, 130V, 20,000 rpm (In case any of that matters). They appears brushless, in that I can't see any.
Near the back of the shaft there is what looks like a disc shaped magnet aligned with a housing containing some sensors, I presume this is to monitor the speed. Am I likely to be able to replace this? Cos i've bust one like a clumsy **** while replacing a bearing.
On another motor I have successfully replaced a bearing but it's now a fair bit noisier, I think I have warped the fan at the very back of the shaft, it was held on by a roll pin and was a real pain in the arse to get off. I'm presuming I can get this balanced. Would this be done with the shaft in or out? Would any (or most) motor places be able to do this or is it a specialised job? There is a local motor place but they'd tell me they could do it if they couldn't and still try to charge. And what sort of price?
Ta for any help.
