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

Brushes.

How old are the brushes in the motor? Very easy to change.

 

[boschlover1997]

Brushes

Try stretching the spring a little, also is the armature clean and unscratched? Watch the motor spin is there excessive arcing if there is the motor is worn!

 

[boschlover1997]

??

which spring? and whats the armature?

...

sorry i must sound really stupid but ive never had to concentrate on the wiring, apart from when i soldered a new cable on for the power.is there a spring in the motor? and again sounding silly, whats an armature?

Oh dear...

Evening,

Sorry to see your 9534 having a little trouble. I will give you my 2 cents.

1. Check all connections and ensure they are clean.
2. For now you can rule out the timer as this does not appear to be a problem related to it. If the timer was at fault here the spin bursts would be either lost altogether or jittery.
3. Check the brushes, to find out if they make contact, release them and if you feel a springiness in them when you push on them then they are making contact.
4. Clean and check the commutator, the part of the shaft that the brushes make contact with.
5. Module could be faulty, there are ones online for £15.

James.

thanks james

the thing the brushes go on make sense as when i wiggle the wires to the brushes.. it works.. kinda.
so glad the module is so cheap.

[boschlover1997]

ok..

so by looking at the pics what do you thinks wrong?

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.
