Lego Under X-ray #1 – Servo Motor

Here is the first article of a serie about lego under X-ray, today we have a look to the lego servo-motor.

I have changed my work in february 2017, from schedule and production manager to R&D mechanical engineer in a company who designs and manufactures CT-Scanner. These machines useX-Ray to penetrate the raw-material in order to watch inside. The well-known use is the radiography in order to see bone-fractures. Our CT-scanner are not specialized in medical field but in industrial field. That is to say is that this CT-scanner are used for looking inside material, parts, assembly for industrial purposes (Material integrity, Assembly verification, Failure analysis) or measure (Dimensional metrology, Porosity and fiber analysis).

What is the point with lego ? The point is that I have planed to do a series of video about lego under X-ray because there is so much to talk and to do about lego under X-ray. For instance : know how the motors are build, how the parts are molded, are the chinese lego bricks worse than lego ? Or scanning whole construction.

The first video is about lego Servo Motor, in dead, I have trouble to make it work properly because I assume a problem of wire. Thanks to the CT-scanner, we can see the inaccessible.

    Hello, thank you ! We use for this computed scan a 150kv generator, set to 70kv to watch the plastic and metal, with a 5µm spot size (after temperature stabilization). If you are confortable with this technologie, we use Hamamatsu X ray generator with Varian flat panel detector.

    […] verify assembly and to inspect for material integrity. It also allowed [Nico71] the opportunity to scan a LEGO servo he had lying around, and which no longer worked. The resulting images look fantastic, and really […]
