What to look for when selecting vacuum motors (EU)

[Boxer Service]

Hello
I am building a PTS flow bench and I am looking for new vacuums motors for the build.
I live in Denmark and we have 3x400V mains (also 1x230V) and the 3x400 is 3x230V
when using each phase with the neutral wire. My plan is to run 3 motors on each phase
for a total of 9 motors.
But I am a little unsure what to look for when choosing the right motors. The ones I
look at for the moment is 1200w each:

Nice price and looks like the ones I know from shop vacs that I previously have repaired.

Would be nice if you could find the cfm/pressure chart for those motors?

I did a quick search and did not find anything.

To me they look on the small side but it all depends on what your CFM requirements are going to be.

Checkout https://www.kemo-electronic.de/en/Trans ... ontroller/ for local motor controls, you will find these discussed on the forum from previous builds
