Electric Motor Howling Sound (Bad Bearings)

[@MattTester]

Sounds like an old Formula 1 car engine now, I miss that howl. I used to abuse the 540 motor in my old Tamiya off roader by submerging it so this noise is pretty familiar actually!

Bearings or Bushings?

[@Macsneese2345]

I have a 5v motor make this sound, now it's gone Also it sounds almost like a car that changing gear 😅

Luckily none of my rc’s or anything have this, but one if my open test motors does.

Sometimes that also means there is stuff jammed in it.

[@isaacsrandomvideos667]

Yup, cause the only one of my motors that makes this noise is open.
