Hi,Erwin
How is the sound? Is the sound very obvious in motor? You can try ,Motor no-load, When motor slow down and stop,Whether there is a clean and grinding sound.
I think may be there is the rub ?the cover and iron core of motor.

Hello looks like it's scratching at the aluminium cooling fan.
At this moment it looks like I have to ship it back to my local supplier.

Hi andto the forum.

If you have fitted a brake disc with bolts that are too long, they could rub against the heat sink cover inside the cooling fan.

If you want to hear what the MPIII should sound like, take a quick look at my video on YouTube.
