sometimes it goes like this and struggles, and sometimes it gets to 1000. sometimes it can only reach slower than this. its only happening when its got a load in CLICK HERE TO GO TO boschlover1997's LINK | ||

Motor
The commutator is the copper bit that the brush presses against it should be quite shiny it has slots in it the electricity transfers from the brush to the commutator causing it to spin.
It should be shiny and clean with no scratches, it can be cleaned with WD40 sprayed on a cloth and wiping it ( I don't recommend spraying the motor as some of the newer ones use nylon in the bearing as nylon and WD don't like each other) Pull Gently on the brush and make shure its moving freely and springy.. Supermaticjames is right the control board my be on it's way out and are easy to find and cheep. Re-fit the motor and run the machine with a lode in, when the motor goes into spin see if there's any arcing from where the brushes sitt againt the commutator. Id there is a LOTT of arcing then the motor needs replacing ( again EBAY quite cheeply) Let us know how it goes. | ||

eddy currents. thats exactly as the fault is. without the belt on its fine, with the belt on and no load, it gets to 1000 slowly and with a load applied it barely gets past slow bosch speed.:) | ||

Armatures Replacement armatures are still available for these GEC/GDA motors in the link below. As a previous poster said, the commutator should be nice and shiny. Tom CLICK HERE TO GO TO hotpoint9534's LINK | ||
