In our application, we are using something that looks like a baloon with two inputs, the volume is ~100 mL
currently this item is made using a silicon dispersion and a ptfe Master is put in this bath 15 times with pauses to get the correct 0.2mm thickness The whole process takes less than a...
Hi all,
When dealing with rubbers, silicons and others, it's rather easy to find data's around shore and all the "elastic" properties of a given material.
The viscoelasticity of those materials is something I am interrested in to evaluate efficiency of vibration dampers and I did not...
I am looking for a very small peristatic (Peristaltic)head to do the following job:
In 8 hours, at ambient T°, 200 to 400 ml of water has to go from one reservoir tank to a chamber where this water will evaporate.
The approximate (huge [smile]) height the water has to climb is 5 cm
A close loop...
In a current high speed motor design,we are using 2x 623ZZ (OD=10mm, ID=3mm, H=4mm) 15% grease filled bearings and a mechanical guy (gone) designed something that we can probably improve .
Bearings :
are hold in housings with a 4-8 µm play
are tight fit on M6 3mm shafts
are 6N preloaded using a...
I have a 0.5 liter volume available to take off 6dB (or more) from a noisy source (motor+fan)with the following constraints/environnement.
-Noise to be taken off at air inlet
-Pressure drop < 2hPa for 1L/s
-noisy source : 42 dBA of broadband noise + F0 + 2xF0 (not dominant)
-F0 can be anywhere...

Hi there,
We are considering acquiring a 3D FEA for electrical motor design,
Currently COSMOSEMS and AMPERE are under evaluation...
Any experiences on other software packages ?
Thanks in advance
Hi all,
I have designed a PMDC axial flux motor for an air compressor based on a toroidal stator with 3 (or 6) windings.
It's a tiny device that runs up to 40 000 rpm with a Back-emf switching mechanism.
All the performances are met : Speed, torque, power accelerations ..... But one isn't...
