no lmao. I did that. I the only thing I can think of is literally the sound of the teeth meshing. When the rotor turns on one of the magnets ya know. I don't have Ultra sonic hearing so my guess is it being amplified by the aluminum motor mount. I know it sounds crazy but thats where I'm at with this.
