@BOBKB3NZX bearings are fine, their a plane shell type like a cam shaft bearing. the high pressure oil feed keeps it safe with the minimal belt tension i had
You are right, 27 amps @480 volt = 20 hp. note I said 480 volt not 440 volt over the 15 to 20 years the voltage has gone from 440 to 460 to 480 I have recorded voltage in the feild as high as 496 volt in Florida US. Its to bad the bitzer comp didnt come with head unloaders. If you are going to use the diesel There is a valve called all-in-one valve for comps runing continuously with out head unloaders it vents the discharge to atmosphere when desired pressure is met. have fun with this project
Are you planning on doing any temperature checks on the motor and compressor? You are overloading both of them at various times. Oil temp in the compressor might be critical over the long run at high output. Running the compressor at high speed could build useable pressure quickly and tapering off rpms could prevent overheating.
@rotarycomptech I'm not sure how much CFM I will end up with in the end but as you said its pretty impressive as it is.
@Jaytheozzi yeah the thing has badass written all over it, I am struggling to find a place to set it up tho lol
Now I know what to do with my 3 phase, 4 cylinder, semi-hermetic compressor when it wears out. Cool!

mad. thats cool. all it need is a good size flywheel.
i laughed so hard when the belt flew off.
Nice! VFDs are awesome.
That's an awesome sounding V4 but i prefer their sound when they are igniting fuel in the cylinders,lol.
uh-oh i heard bearings going crunch crunch! get that end pate machined!
that will make an wicked static show piece regardless
nice!
good to see it in progress!

Uh oh- reverse? Don't forget about the oil pump... :)
@Aussie50 good to hear, have any ideas for when the end plate will get machined

I wonder if a VFD would run a Fisher & Paykel Smart Drive motor, If it can provide the right frequency & Voltage, I'm Curious of that
@tech4pros Ohh, that'd seem right, they are basically a stepping motor
Looks like the inside of a thunderbolt Siren's blower
Just wanted to mention that over 50/60Hz (depending upon your location) the motor HP starts to drop.
@bcordasco depends on the motor design.
UN PASSIONNE
the vfd works good for testing a5 hp air comp puts out about 18 acfm @125 psig you got a hell of a lot more cfm than that
hmmm, My VFD i just gotta set up for more torque, It's good, but i'd like more!!!
2:32 Doh!
cool vid
can we use these compressor for a homemade air compressor ?
+Panos Sarikas This guy is hard to reply on a comment. I believe You can use it as an air compressor as long as You maintain the oil inside.

3:20 sounds like a car!
5 horsepower maybe? lol
Thatslouls
really dangerouse compressor they have 100 rpm to get presure air for ac motor the blue motor one once again
