MOST Accurate Motor In The World - PiezoUltrasonic Motor

Ultrasonic motors generate motion based on resonant behavior in a piezo-ceramic actuator. Motion is transferred from the resonator to the part to be moved in nanometric increments, but at high frequency leading to smooth, continuous motion. Precision positioning devices based on ultrasonic motors can be very compact, and allow for very fast step / settle behavior

The level of percission my bathroom tap needs to get to the optimal temp:

Modern lens focus motors utilize versions of this technology. Nikon's Silent Wave Motor, and Canon's Ultrasonic Motor. Both use piezo actuation to precisely achieve focus.

In another form, used for sub micron positioning and alignment of optics to distinct wavelengths of light.

I too can change shape when an external voltage is applied.

Nanometer precision so long as you’re keeping room temperature just as controlled…

We used to call piezo motors "banshee motors" because of how loud they would scream when in motion.

This might be the most accurate motor straight from the shaft but the JWST mirror trim motors insane levels of accuracy

[CyberSorceryCodex]

Amazing insight into the inter mechanisms this type of motor or engine

[vendomnu]

The way he said 'lab equipment' makes me suspect he knew what I was actually thinking about.

[lemmonsinmyeyes]

the fact these litle guys can also be encoded is just so wild to me. oh, and they are WICKED expensive

[MLWL]

Very cool, but I assume it has very low torque no?

[allanallsopp]

the plane left and I'm still looking at departures

[julenlaskibar]

1000mm/s is... I can't believe it. I need proof.

[meggawatts]

Ultrasonic motors are also very important in camera lens focus assmeblies

[XiYen]

How much torque can it put out though? 🤔

[alpha_pixel_]

Some camera lens use similar technique with ultrasonic vibration.

[mitchek]

What's the failure rate and precision integrity compared to a similar regulator motor or servo?

[EarthMedia_Space]

Someone should build a rotary vane engine with these.

[flyingfajitas]

This could be used to help with wire icing issues in high latitudes.

[markhammer]

They probably have them at the high-tech lab where I work as a janitor. 😂 Just kidding. It's called a custodian.
