Hi
I've had a a grinding noise coming from the motor of my 905se for a while now and I'm looking for a bit of advice about it. To be fair, the noise is not new. It has been going on for quite while, without seeming to turn in to anything nasty, but I feel I really ought to check and see that nothing serious is up.
The noise is not there all the time, it is only evident when the motor is under significant load, eg.when climbing a relatively steep hill and it seems to become much more noticeable as the battery power level drops. I think I may have heard somewhere that it might have something to do with the 'firing' of the Hall phases in the motor under heavy load (in which case nothing too much to worry about), but any insight would be welcomed.
