Thank you ariovaldo. So it is closer to 0.026 per side.

No, he has the rotor all the way over, I think, so he's showing that the total gap is 0.026", or 0.013" per side. Very impressive!


Ariovaldo, can you describe for us the difficulties in achieving and maintaining this close clearance?
-The concentricity of the 4 stator pole piece arcs and the rotor bearing mounts and rotor faces.
-The rotor symmetry and balance.
-The rotor shaft bearing mounts.
-Checking clearance after assembly.
-Thermal expansion.
-Vibration when resonance is attained.
-Results of an inevitable rotor crash.

etc.

I see what you mean. My be I misunderstood ariovaldo. I to am curious as to the set up procedure. Once the side plates are up how do you measure your gap?

[ariovaldo]

Thank you ariovaldo. So it is closer to 0.026 per side.

Nope. It is closer 0.013 per side. I inserted the wire just one side. The other side the rotor and stator was touching each other..

I don't say that is difficult...I use to work with 7000 hp gearboxes and when we take it apart, to put it back needs adjust to get good contact in the flanks and the clearance right.


Now, trying to answer yours questions...
-The concentricity of the 4 stator pole piece arcs and the rotor bearing mounts and rotor faces.
The concentric are very good. I got tell: It is a beautiful machine. The rotor and the stator was well done.

-The rotor symmetry and balance.
No balance problem. I put the SKF vibration monitor and it was in a very good range..

-The rotor shaft bearing mounts.
This is one problem that I'm having...That shaft was made using one " non"  reliable lathe ( my fault), so it is a little bit smaller in diameter that was suppose to be.


-Checking clearance after assembly.
I don't use to check. When I'm putting it together, I use to put the rotor in the lower position, making it touch the stator, after that put up position and bring half way down. Repeat the procedure for the side

-Thermal expansion.
I don't think that is happening in this system so far, since I din't run long enough to have the system hot..Can be a problem...

-Vibration when resonance is attained.
The vibration can be felt in low speed, but this issue is not something that is calling my attention so far.

-Results of an inevitable rotor crash.
That can happen in a long run and when we don't use the right material and as washers for example. Also we need to have right torque and etc..


The difficulties that I'm facing is inherent a system like that, where we have a small clearance, high speed, plastic as support and nothing to lock in the right position.


I hope this can help.


Cheers
