BOLTR: Japanese Linear Compressor | Genius!

[@bobski3333]

Two things: If the pump is rated to run at/on 50Hz, the reciprocating assembly should be engineered to resonate at 50Hz under rated load. If you give it 60Hz, you're starting to push the swing before it's returned as far as it can. Second, you should be able to get higher voltages out of that variAC by using it backwards - swap the input and output. Just make sure you start with it cranked to what would normally be all the way up (primary:secondary windings are 1:1). As you turn it "down" you'll be reducing the number of primary windings (the bottom half of the fraction) with a fixed number of secondary windings (the top half). That'll boost the voltage rather than reduce it. At the "bottom" end, you'll be flying off into the cosmos voltage-wise. The insulation and air gap on the windings won't necessarily handle anything over ~130V, so it'll eventually start arcing internally and turn into a Photonicinduction episode.

[@williamward2948]

What 'bobo' said... The copper lines are thicker/stronger. They used r-12, not r-410 or butane. The windings in the compressor motors were of larger gauge wire for more amperage capacity/higher hp to combat head pressure lock up and frying the motor. And also, a lack of a thermal fuse prevented it from shutting down for good when it did eventually overheat. We got an old commercial GE beer cooler that fires up and rattles like a diesel, and has been running strong and keepingthe beer cold for 50 something years...

Reciprocating linear compressors are also used on laser engravers inside the laser nozzle to keeps positive pressure that keep fumes and smoke out and thus the main focus lens remains clean. It also helps clear the ash away from cuts and engraving so the laser has a clear path to the material so it can go deeper. Especially useful for wood.

These make great pond aerators, and are also used in septic tanks (frequently interchangeable terms in my experience). Much quieter when enclosed in a housing. I've seen a small one of these (60L/min) run continuously for nearly a decade. I replaced the filter once or twice, and brushed the bugs and webs out of it annually. Quite reliable. IMO, way better than similar diaphragm pumps.

[@Majromax]

With a rotary motion, you can always attach a gearbox to exchange rpm for torque. For a linear motor, you can't use that mechanical advantage and have to work electrically. High torque/pressure would require high current, since in an inductor/coil the EMF is proportional to current. But with a high current, your electrical losses would also skyrocket -- losing whatever efficiency advantage you may have had to begin with.

[@xenaguy01]

Sortof a funny thing to be proud of, considering that there's been some linear compressor fridges since at least the 70s. My '73 motorhome has an original "dual voltage" Norcold fridge with a "swingmotor" compressor, which is just one of these in a can. It's dual voltage because it has an inverter built in to the base for 12 volt operation, which is louder than the compressor is.

AFAIK those things are designed to mechanically resonate at the line frequency so it was probably suffering a little being driven at 60Hz instead of 50. It will probably push a lot more air if you run it at 50Hz, maybe with a VFD.

It is just a coil, handles switching frequency just fine, so maybe vfd.

[@BigIggy]

Box is open. Still cuts box. You sir, are my spirit animal. ...Thick PP lol

[@1n5ane1]

it's pretty simple why linear compressors aren't used, mechanical force multiplication is simpler and cheaper. Consider something like a a tire inflator compressor with (for argument sake) a piston surface area of 1 square inch. To get up to 90PSI, you'd require over 90lb of force to move the piston in the compression stroke. A linear motor coil that could do that would require an insane amount of current and very thick windings. However, this is very easy to achieve with simple gear reduction and crank mechanism (what you find in typical compressors) and would allow the use of a smaller motor.

[@paulbillings1791]

Note all the moving parts you just described. Different beast for a different purpose.

[@Jasoninee]

The same thing can be done with the pressure and piston. Notice how you randomly decided it has to be 1 inch? It can just be made smaller and there you go, more pressure. Literally exact same concept of mechanical advantage. Force vs speed.

[@1n5ane1]

@paul billings - I was merely responding to AVE's question as to why they're not more commonly used. Fewer moving parts, sure; but consider how most compressors fail, it's usually in in the piston to bore seal or reed valves. It is very unusual for the gear reduction or crank mechanism to fail. A linear motor compressor still has piston seal and reed valve.

[@Jasoninee]

@@1n5ane1 I know. I was merely responding to what you stated. It is not hard to multiply/divide force with pressure of pistons as you claim it is.

[@1n5ane1]

@Jasoninee - The size of piston I was referencing was more in line with a typical tire inflator compressor. You could absolutely decrease piston surface area to decrease the amount of force required. Say you used an absurdly small piston with a 0.1 square inches of surface area, you'd still require solenoid that is capable of applying 9lb of force (to reach 90psi). This would still require a fairly substantial solenoid, try looking up the current specs of a solenoid that can do this if you don't believe me. Another consideration is controlling the speed of the piston as you'd end up having to run the piston 10 times faster in order to match the performance of a larger piston; this is very difficult to achieve with if powered off 50/60hz mains, you would likely need a fairly complex inverter. When it's all said and done, it's pretty clear these are non-trivial requirements. I'm not saying that this style of compressor is useless, just pointing out the limitations and reasons this style of compressor isn't more widely used.

[@Obsidian0Knight]

The reason this isnt used when higher volumes of air are required is 100% a scaling thing. Remember in the one you just opened up the stroke on that puppy is most likely less than an inch. The issue with solenoids in general is its hard to have a long stroke and a quick reciprocation. This is because as you make your coil more and more massive to accommodate the larger stroke you then end up with issues of dwell inside the coil.

[@richarddale76]

I suspect having a hefty bit of rotating mass to keep it turning "smoothly" is quite helpful for a reciprocating system that needs to supply any kind of pressure. You have some inertia to help on the pressure stroke, while the motor can continue to make up for the used energy on the intake stroke, thereby smoothing out your power draw a little. Also, a little mechanical advantage from the crank configuration?

I think they are limited in the volume of air they can move by their basic design. If the cycle of the pump is tied directly to the hertz cycle, you have a maximum output speed. With belt driven compressors, you have the gearing advantage to get more compression "cycles" per hertz by just installing a larger motor and/or different pulley ratios.

Good luck getting 130+psi and a decent refill rate on a linear compressor, especially if you have only a 115V 15A circuit to work with - you'll need a lot of peak power to get the piston to bottom out and force every bit of compressed air out for maximum efficiency. With a rotating motor, you have the motor and pulley/gear momentum smoothing out those peaks.

[@Ratlins9]

Thanks AvE, on the door of my LG refrigerator is an inscription that reads “ Linear compression .” Now I know what the hell they are talking about. Excellent video.

[@l.george7517]

Ken, I hope you LG is still running. They ran the liquid refrigeration line thru ghe condensation tray to help cool. However the alkaline condensate eats thru the copper. Isolate that line from the water and it will last. Although the parts are warranted for 10 years, the labor is not. $1,800 labor the replace refrigeration system and they will not send you the parts, only a qualified shop.

[@iamdarkyoshi]

Put the coils in parallel with the diode on the incoming supply and it'll run on 120v

[@shurdi3]

Gonna have to replace the diode for one that's rated at twice the current as well though

[@nf4x]

Or should at least check the rating on the diode. Given the size, I'd be very surprised if it wasn't just fine for twice the current.

[@dandevries7124]

The two coils could be wired in parallel but they would have to be in series with the diode.

[@johnpossum556]

mathematically it only takes about 200ma but it looks like they used a 3amp barrel diode just to be on the safe side.

[@ramosel]

or you could pull the wires off the coil and hook them to a real compressor and actually get something done...

[@skokie23]

My LG refrigerator has a linear compressor. Same animal? Keep the vids coming AVE! GREAT STUFF!!

[@kabadisha]

My bet would be that linear compressors have a low maximum pressure and cost increases significantly with pressure. Common motor driven compressors won't have the same issues.

[@shurdi3]

The max pressure is essentially dictated by the spring though, since that's what's actually doing all the compressing. Probably gets quite power hungry trying to pull back really heavy springs, so you'll need wires that are much thicker for the coil. That alone will probably cost you more than the electric motor

[@MascottDeepfriar]

exactly what i was thinking.

[@jimandaubz]

Ya. Seems like it, you would need to replicate the entire motor for every cylinder too and everything would be overly complicated to get good pressure. But it definitely seems possible, but, then again. For what gains, 2% or less in friction losses? And no ability to use cross platform parts? Thats a lot of cost incress for those last 2%. Not worth it. Ps Did you mean reciprocating with the rotary motor? Because rotary compressors are a whole different animal, really good at high volume and terrible at high pressures, they bend the vanes if you push to much through

[@kabadisha]

@@jimandaubz I did mean reciprocating with a motor. Didn't even know true rotary compressors were a thing. Learn something new every day!

I found one of these in my father’s cold therapy machine after he had surgery. It was pretty cool to play with as the pump itself was all contained in the box/wall wart with the pneumatic tube coming directly out of it.

[@ElectraFlarefire]

To convert from 240 to 110: Cut the diode between the two after the stripe.. Connect the brown wire to it instead.. Then connect a second blue wire back to the start of the second coil(where the diode connected).. add a second diode and a second brown wire afterwards so you have two N->coil->diode->A in parallel. That should do it.

[@AlBarathur]

I love simple and robust machines just like you. But these reciprocating motors have their own limits which is why most higher power applications will use regular circular motors. Ventilation is one of them ( if you think about it any circular motor only needs some blades installed and it got its own fan, now reciprocating motors of higher power output would need external fans, which defeats the point of them being simple and robust since that smaller less reliable external fan is what would keep the bigger internal motor from destroying itself. Another problem is the hysteresis. As you scale up a "back and fourth" type of electrical motor, the sheer weight of the parts make it unable to move at 50/60 Hz speed. Problem the third: You saw for yourself, the heart of that thing is a spring. So underneath that apparent superb reliability, you have machine that is relying on bending a piece of steel back and forth until it breaks. Myself I have imagined solutions for that, but the results I got made a circular motor look simple because my solution needed a kinetic energy accumulator (a fly wheel) like old time steam engines and my back and fourth motor was no longer functioning on 60Hz but it worked on any voltage frequency since my motor was only working as an electromagnet and relied on electronics to switch on and off. The electronics were solid state but they had to be oversized on account of the switching of the coil (you know how coils don't like to be switched off, they do like your wife when you tell her she is talking too much)

[@richardgreene6810]

Isn't it also easier to throttle a rotational electric motor?

[@testuser9t881]

car valves use springs. There are a lot of these operating at thousands of cycles per second and usually none break

Replaced one of these for the dryer cycle in a dental autoclave. One coil had failed due to the intake being inside the case that caused it to fail due to years of moisture. They eventually fixed the problem with the intake outside of the unit with a dust filter. Cool you posted this little breeze of a fart machine lol.

Due to the sealed unit, you could hook them up in series and get a pretty large pressure boost.
