Title: need used, burnt 2204 motor Post by: rastsaurabh on December 14, 2014, 01:02:16 PM Hello Fellow friends
I am looking for the turnigy 2204 motor which is burnt and not usable... i need the outer cover.... i somehow spoilt mine.... Magnets lost the magic...!!! Title: Re: Post by: sanjayrai55 on December 14, 2014, 02:38:27 PM Why? How?
Title: Re: need used, burnt 2204 motor Post by: KALYANPRODHAN on December 15, 2014, 10:46:18 AM Magnets are fixed with outrunner by epoxy. How they lost ? I see the prop fixing screws are missing.
Is someone opened the motor and take away magnets ? Then even after taking another one, you may still lose the magnets from new casing. They are very good motors. Check them at hobbysea.com available at 869/-. Similar speed power/weight/KV motor available at RCBazaar but with different dimension and very low stock with less price... You can try.

Then heated outer cover to remove the shaft .... the shaft got removed quite easily with 2 hammer strokes. and The magnets too lost power !!!! :'( People later suggested to keep the rotor in Freeze for 6-8 Hours to remove the shaft. Anyone with a motor outer to spare.... ( burnt motor etc.) regds Saurabh Title: Re: need used, burnt 2204 motor Post by: SK1701 on December 15, 2014, 07:07:12 PM Looks like that's the problem. From the few disassembly videos I have seen, a mallet is advised to remove the shaft. How severely did you heat the motor bell?

I don't know at what temp. a magnet loses it's magnetism though ! Title: Re: need used, burnt 2204 motor Post by: rastsaurabh on December 26, 2014, 10:23:32 AM 2204 shell or 4x4mm Magnets... anyone??
