Worn

That looks quite worn try cleaning it as described above but it may be time for a new or reconditioned motor. Make shure the brushes are seated properly. Dose the motor spinn freely when turned?

 

[boschlover1997]

yeah

yeah motor spins fine, although it does slow down quite quickly

 

[brummybear]

refit

You may also want to make shure the drum is free to move also,

Arcing

If the motor arcs badly when spinning its time to replace it, not replacing it my fry the control board too

 

[boschlover1997]

sure?

so your sure its the armature??

 

[brummybear]

75%

Thats why refitting and watching it spin with a lode in ( not empty) some arcing is normal but a lot means buggerd armature.

 

[boschlover1997]

okay

okay whats the best website of getting them from?

 

[brummybear]

Ebay

Ebay is good, or espares ( Google it) But do refit first after cleaning and watch the motor.

 

[boschlover1997]

okay so i need to take the armature out and give it a clean? and then test it again?

 

[brummybear]

No.

No Just take a cloth if your fingers are small enough wipe the Copper bit through the hole that the brushes go. Use the shaft of a wooden spoon with a little WD40 on the cloth while turning the motor.

The refit and test

 

[boschlover1997]

ok

will do that tomorrow

The commutator looks fine to me but you do need to see all round it in case there is a burnt spot or a copper strip poking up. There is a rare fault involving eddy currents which causes the motor to lose power. If that is the problem it will spin fine with the belt removed but slow down with any kind of load applied. If you do need a replacement armature you can use one from a later model such as a First Edition but you have to use your original tacho magnet (the round magnet screwed to the back end of the spindle).

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.

 

[boschlover1997]

so how do i sort that one out then?

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.

cheers

everybody, thanks so much for your help. it turns out it was the armature that needed a clean, ive cleaned this and now ive done a wash cycle in the machine and it worked fine. spin cycles are still a little slow but by slow i mean the 500rpm is about 400-450rpm and the 1000rpm final spin starts off at that and ends up at about 950rpm. i only know this because i can just hear it dropping slightly. but its good enough, everything comes out dry enough and it doesnt struggle very much at all.
thank you all so much really appreciate it.
cheers, george.
