Talking Mini Brushless DC Compressor

A friend of mine recently acquired a small brushless DC compressor for me to work with. He would like to develop some mobile cooling devices for a teardrop trailer he is planning. I was going to build a small air to air cooling system, but with the temperature dropping lately, and the relative humidity rising, I'm going after a dehumidifier for now.

Look at the pics; isn't it cute!?

It's a rotary compressor, 2.7cc, 1700-2900 RPM, 50mL oil, 12VDC

Other models are available which have a high speed of 6000 RPM, and other voltages as well.

eBay listing for 12VDC Refrigeration Compressor - Brushless DC

I've had an interesting time checking and changing the oil in the compressor. Displacing/burping the air is the biggest issue. I utilize a large syringe and needle, along with a very thin tube attached to the needle, for the job. Oil migration is an issue, I'm sure.

I'm running a capillary tube system right now. It is too long, so I'll be shortening that today.

Somebody else should buy one of these, and build something!
