12V Electric Motor for Car Compressor Capable of 10 Atmospheres & Long-Lasting Performance

Question

I do not know if this is a good department, but the question may be a bit unusual, so I am asking here. I need a compressor in my car. It is supposed to pump air up to 10 atmospheres. And the easiest way would be if it was powered by a 12V electric motor. Traditional, reciprocating compressor, e...

The best engine would be used in power steering systems, look for something used because they are quite expensive.

By coincidence, I know that the compressor with a pressure of 10 bar in hydrogen-powered buses is driven by a 4kW motor at 400V AC.

Rather, I do not think that it is possible to choose a 12V motor, it comes out 335A of the rated current. Of course it all depends on the pressure output, but I don't think a fuel cell bus needs less compressed air than a traditional vehicle.

What performance or for what specific task. There is no more reliable solution than picking up the drive directly from the crankshaft pulley. The 12V electric motor sounds cool, but even 0.5kW is a huge load for the alternator, which rarely has excess current efficiency ... What's more, you can pick up the clutch from the air conditioning compressor by anticipating the next questions.

The easiest way is to convert the starter to the bearings.

Yes, they are, you can easily buy:

Staszek49 · Answer

It will be difficult for you to use such a device in a car (probably a passenger car) due to the high demand for electricity. If you have a bigger car and a more powerful engine, you can use it to drive a traditional compressor. In this case, select only the place of its installation and install an additional pulley. If it is to be, for example, a (special) demonstration vehicle, which will sway and jump with the aid of pneumatics, then I suggest installing a larger air tank, filling it with a compressor first.

What is this pneumatic installation intended for? Is it supposed to handle the brakes of the trailer, or is it to be used in an unconventional way? What is more or less air flow, because 10 bar is even a Chinese compressor for PLN 30 for pumping the wheels, connected to the cigarette lighter socket, but the pressure is only one of the parameters, you do not reveal anything more to us.

vodiczka · Answer

Exactly, many 12VDC compressors are available for low air flow.

fred77 · Answer

The air will be used only for the pneumatic horn, for inflating the wheels and for blowing something with compressed air.

WędkarzStoLica · Answer

Then you have to look for a smaller compressor Then the 12V bicycle motor - they are cheap, strong and adapted to continuous operation.

Strumien swiadomosci swia · Answer

A Chinese compressor is enough to inflate the tire and a small tank too.

Anonymous · Answer

VW and Audi are factory-equipped with a compressor for 12V 10 bar. There is also a pressure gauge and an attachment for inflating the wheels. Unlike Chinese, they are reusable.
I pump the 16 "tire in a minute, I checked it, I have one in my garage. Ask at the racks or on the portals for a used one.

WędkarzStoLica · Answer

Could use something more efficient and not with a plastic plunger

teskot · Answer

I propose a wheel compressor for off-road cars plus a cylinder, a safety valve, a pressure switch and a relay. Such a compressor has a power of 300-500W, quite high efficiency and decent build quality. I know because I use it myself. It costs about PLN 200. An old fire extinguisher can be used as a reservoir. For this, of course, a solenoid valve to start the horn and the appropriate pneumatic fittings for connecting the peripherals.
