One-wheel Plus noise while stopped
-
I just got my one-wheel plus and it makes a moderate grinding noise when engaged but stopped. As if there's something spinning in there when it's completely stopped. Anyone else have this problem?

Normal noises ride it
-
@cascadewheeler I have an original one-wheel and noise while stopped is not normal.
-
I have 2 OW+'s and they both do it in Delirium mode. No noticeable sound on the other modes. I consider it normal for the PLUS.
-
Brushless DC motors can make a crazy amount of noise and a variety of different sounds depending how the stator pulse timing and power are applied, it’s really fascinating. My racing drone pulses the motors to make a beeping sound on startup that you’d swear is from a speaker.

something spinning like..... a gyro?
-
@nicktulloh the gyros are embedded in microchips and definitely don’t make noise. The noise heard is the 100% normal chatter of a brushless DC motor making torque at low RPM

So it's not actually a gyro? They are motion sensors.

Most gyros-on-a-chip are MEMS coriolis gyros (vibrating rings whose vibration modes rotate while the ring itself does not) or fiber optic gyros (where a light pulse in a a fiber optic loop is the "moving part"). Low-end MEMS gyros run about $2 in large quantity and can be only a few millimeters, so that's the way I'd bet.
So actually a gyro, but a really tiny one with very little inertia. And really tiny gyros can "spin" physical abstractions like vibrational modes and photons rather than hunks of metal. It's the same physics and math as a classic gimbal-and-ring gyroscope, but tiny and cheap and won't take your finger off if it slips.

BLDC's can also be used to play music. LOL...

@ow-miami that’s dope I wanna make a motor synth now!
