That compressor looks identical to the compressor in the GA8 Airvan hot box I mentioned earlier. That would be the technically correct solution to this whole problem. As for BLDC I'm workign with a gentleman that does custom BLDC for Military UAV systems. ecerts and all of that, jsut not FAA aproved...

yes the motor is placarded at 52A.
The aircraft maintenance manual says it should be running at a max of 45 A
(Implies running at less than full load as a conservative design should)
Mine is more like 60A

The motor you quote is 42lbs. The motor I'm trying to replace is <15lbs.... I have not found one of similar weight that was not brush-less... The other possibility I'm looking at is replacing the whole assembly with a a "hot" box out of a G8 Airvan airconditioner system. not PMAed, but on ...

There are people that say the electric A/C works fine. There are also people that have similar issues.... This is complicated by the fact there are two different electric A/C systems. When the motor test comes back with results I'll make a decision.... There is a 9K STC to switch from Electric to en...

GPU is home built from a 24V 100A 220V Server supply and a pair of deep discharge 12V batteries... The voltage is well regulated at 28V. At one point I drained enough refrigerant that it ran for an hour on the ground providing marginal cooling, but with the vibration of flight popped the breaker in ...

This is in a aerostar. The compresor turns freely and has oil. No tight spots or other issues.... I've tried ALL three motors in place all behave the same. Given that I went to measure the no-load RPM at 28V using a laser tach. I aborted the test when the motor hit 14,000 RPM This may be a shunt wou...

Can't seem to get the motor picture to attach even shrunken to the point its unreadable the upload says too big.

Here is a link to the motor picture...

The pulley bearing is fine. Clutch not used at all.

I have three motors, one origional, one from an airplane scrap yard and one from Ebay with the correct model number. All three have no bearing issues. The original seems to have some serious brush wear. The other two have good brushes. Can't find the exact motor specs to test properly. Io (ie idle c...

System is sealed so should be no pressure change inside the system. So far all testing described has been on the ground at sea level. At Altitude one might expect the condenser to be less effective, but outside air will be colder. I reality at crusing altitude don't need A/C. A/C is 90% for taxing o...

Upfront this is not in a CAR, its in an Airplane. Its my Airplane and I have my Aircraft Mechanics license so its legal for me to work on it. When I comes to A/C system I'm lost. The system is 1980's vintage. (Both the A/C and the plane) It has a York EFR210 piston compressor driven with a a large 2...
