Got given this breaker to fix, armature had failed so replaced and the same thing happened.
Its a 240v heavy duty breaker as opposed to site 110v.
The 1st armature was bought from aliexpress and advertised as 240v but burnt out within 2 minutes light use taking the 13amp fuse with it and the 2nd bought from ebay (german seller) started to get very hot and begin to smoke so hopefully saved it by shutting it off quick at the first sign of smoke but have now tested the x2 safety cap and its not reading 0.22uf, much lower.
Theres very little to it really on the electrical side - 13amp plug, lead, switch, x2 safety cap, ring coil, brushes, motor field and armature.
I had thought possibly the 1st burnt out due to the fan that attaches to one end of the armature was free spinning or not spinning at all so not providing the cooling affect needed however this seems fine.
Would the failed x2 safety cap cause the armature to burn out? Personally I dont think so but shall replace, of course.
It does seem more plausible that the replacement armatures are in fact for 110v given they are burning out so quickly.
I did notice that the hammer action didnt seem very strong and although full hammering is only expected after a few minutes use it certainly was nowhere near as expected from initial start-up.
The gears, conrod, piston etc all move freely and appear in good condition on inspection and move freely when turning the armature by hand so nothings seized or broken.
Am I missing something perhaps?
So field failed causing armatures to burn out or replacement armatures not 240v? Presumably theres no easy way of telling if field has failed or differentiate between 110v and 230v armatures.
Thanks
