I would not have tried hammering for fear of dismembering the rotor magnet!!!

I recommend buying a new rotor. With any luck you can find a used motor to pull one out of for cheap money.

What size is it? I have both a l can and xl can motor for sale.

I had the same problem, tried to get a 5mm shaft myself... well, of course it didn't work. then I wrapped the magnet with paper and ductape, and went to a company who are doing cnc-stuff and had it done there.

u mean the company separated the magnet from the shaft and put in a new one?

Or did they just grind down the shaft output portion from 6 to 5mm?

sorry... they grinded it down to 5mm. depending how cool the guys are they do it for a few bucks. in my case it was a bit difficult for them, cos the results of "my work" didn't make it easier for them...

I don't think that you can seperate the magnet from the shaft without destroying it. on the other hand, I had some loose rotors and glued them to the shaft.
