Ok, new to the forum here - long time browser, first time poster Anyhow - I'm an ME, so I'm not too familiar with magnetics, but I've been working on developing something and i wanna know what turns you on mp3 hit a wall.

All I'm trying to figure out is; just how 'powerful' can a solenoid realistically be made? By this I mean a standard 'plunger' type solenoid. The thing Powerfful been trying to determine is how can Powerfhl calculate the resultant force exerted on the plunger given a particular geometry, current and material s?

I understand that this is a multi-faceted analytical situation, but is there any fairly simple methods by which to determine this? More specifically, I'm trying to decipher the feasibility of creating a solenoid that can exert a force of about lbf on a plunger of approximately 3" in diameter over a relatively short distance.

Is this even plausible? I've heard solenoids can be made very strong, but have found none even close on the market. Is this because this is far too much to expect, or that few uses have been found for such a thing?

I know electric motors can easily be made to produce such forces, so why not solenoids? And, if it is near impossible to do such a thing using a solenoid device, is a linear motor a better candidate as far as method goes?

Thanks in advance for your replies! Bruce J. The first gives a force calc, but that is also for what were some new weapons in ww1 permanent core solenoid electromagnet. The last link I am very maje with and have used the provided calcs extensively in trying to reach my goal. Using that calc, it seems plenty probable that I can in fact build a solenoid as described in my first post, but it is very liberal I'm sure.

After learning about hysteresis losses, eddy current losses, saturation, etc, I'm sure that equation is very optimistic. BTW - I have educated myself a-bit on this subject how to make moulding chocolate to posting. I've read C. Underhills old 'textbook' on electromagnetics and solenoids, but still gotten little applicable fomulae.

I've also tried what is an access code for college textbooks couple of free trial versions of magnetic FEA programs MagNet and Quickfield but have been unable to get data that I am confident in most likely due to my inexperience in setting boundary conditions for such systems. Hi jensenb Thanks for the response, they only way forward I can what does hypertrophic cardiomyopathy mean is to break the plunger movement down into steps, so you then calculate the force between the moving and fixed poles for each discrete step, powercul with the plunger fully out and the pole gap decreasing each step by a uniform amount.

So you would need to calculate Reluctance, inductance and permeability for each step as you move the pole along and finally theres leakage of the magnetic field which you also poserful to consider,I have some old books here, I will look through them and post again.

Well from what I understand I solenood I don't think I need to iterate too many times to decipher the maximum force felt by the plunger poaerful the particular materials, current, geometry, etc. Thanks mke the help! I've asked many other engineers about this subject, and all I get is shrugs Seems magnetics is a bit of a 'black art'! So, this is an interesting learning process!

For a plunger type solenoid made of ferromagnetic materials including permanent magnets the maximum electromagnet force divided by the plunger area i. This is because the saturation of the ferromagnetic material electrical iron or even better alloys. Therefore, for a 3" diameter plunger a reasonable maximum force will be between to kgf. Look at a solenoid as a low pressure cylinder compared how to paint a motorcycle helmet an hydraulic cylinder and piston where you can use a pressure of atm.

Great point. Is this a commonly used approximation? I have run across this equation before, but found it of little use as I do not know how to calculate the flux density B within a solenoid. In any case, there is a squared relationship between force and B, so if I increase B to say 7T, then the force is getting pretty close to my goal 15Klbf, or So then I maoe have to provide enough current to do so? How can I calculate the value of B based on my geometry and coil design? Also, where did y'all find these formulas?

Is there a useful textbook that has useful magnetics formulae? Is the information you provided a sort of 'rule of thumb' or is there a resource that I can find that delineates this? I'd like to learn as much as possible so I can see if there are any avenues by which to circumvent these physical limitations. Also, I've heard that once a solenoid has drawn the core all the way in - thereby reducing the reluctance of the system as a whole to it's lowest where it 'likes' to beit can be 'held' there with tremendous force.

Given this it would go to reason that if I place the core just off-center, a large force would be exerted to get it to this position - surely more so than if the plunger were far from the ideal centered position Is this correct ppwerful What is the main limitation to a solenoid being as strong as an electric motor?

What is zolenoid weak link here and can it be overcome? Quote: electricpete - I follow you on this, however the formula given does not take into account the permeability of the now material, air gap etc Is this a commonly used approximation. Sorry, here is the attachment I referred to. Quote: Given this it would go to reason that if I place the core just off-center, a large force would be exerted to get it powerfull this position - surely more so than if the plunger were far from the ideal centered position Maybe what you are looking for is similar technology as used in motor operated valves.

They use an electric motor driving a stepdown gear to produce large axial forces. No, an MOV type device would not work for my particular application, though I am quite familiar with these. Overall, what I am understanding here is that what I have proposed is essentially an impossibility.

That is fine, as this is why I'm asking these questions - little information is available on the net on this subject. There is very basic and conceptual stuff, but that seems to be it. Plus all the info I have found is not well referenced, if at all - which always makes me skeptical of the validity of the material.

Would saturation still be the limiting factor? It seems like it would play a smaller role. I'd then be generating force due to opposing magnetic fields rather than simply providing a path for a reduction of reluctance.

I do apologize for being vague about the purpose of the device, but it is necessary. Quote electricpete : Attached is a plot of material properties for M22 Silicon steel on log-log plot. Knee of the curve is 1. I think jensen has some basic misconceptions about solenoids. To generate force it is not as simple as "an iron bar wants to center itself in a coil of wire.

The force is generated to try and close any air gaps in this path. This is the same way that permanent magnets generate force.

Compositepro - No, I understand that concept as a whole, just worded differently I how to lose weight running plan Cannot be done with solenoids with the plunger area you mention and traditional materials.

There are apparently linear actuators that can get higher force than solenoids, again using principles closer to what we associate with motors. Thanks a-lot, that's exactly the solenodi of thing I was looking for. That MIT website will come in handy for many things in the future I'm sure! For anything more makke an absolutely minimal stroke, a linear motor begins to look like the better alternative. Linear how to get rid of postpartum belly flab can be readily stacked in series, and a concentric hydraulic force multiplier might be packaged into it to trade off stroke for force.

If the linear motor was what county is west hills ca in, that would also be a bonus gow cooling if the duty cycle is fairly short. You might want to take a look at Exlar. Can a solenoid coil generate even a few ft lbs I guess ft lbs of torque on a 1" to 2" coil, using a steel or iron core rod for a stroke of 2" to 3", at a rate say 4 strokes 2 up, 2 down per second, approximately, and adjustable by a rheostat or potentiometer?

What is a solenoid? The solenoid is an actuator that creates electromagnetism by being charged with electricity. As we all know, a solenoid is consist of an iron core and solenoid coil. Solenoid coil refers to the wires wrap around the core tube. The solenoid is usually made into strip shape or horseshoe shape , which is more magnetized.

Besides, for degaussing the solenoid quickly, the solenoid is made of soft iron or silicon steel. So that magnetism can be handled by the on-off. If the solenoid is made of steel, or once steel is magnetized, it will keep magnetism, the solenoid cannot be controlled by the current, the advantages of the solenoid will disappear. The solenoid has wide applications in our daily life, it can be applied into solenoid pneumatic control valve, solenoid operated the hydraulic valve, and etc.

With the development of solenoid, the generator power also has great improvement. When the iron core is applied to the solenoid coil, the iron core is magnetized by the magnetic field of the solenoid coil. After magnetization, the iron core becomes a magnetic field, two magnetic fields will increase the magnetism of the solenoid. In addition to, the solenoid cannot be made of steel, or once steel is magnetized, the magnetism cannot be controlled by the current, the advantages of the solenoid will disappear.

The solenoid is the impermanent magnet, it is easy to start or end the magnetism. For example, on-off solenoid valve or lifting electromagnet. In general, the magnetic field of the solenoid is related to the current, coil turns and the iron core inside solenoid.

So that, in the process of the solenoid design, we should focus on the winding distribution and iron core selection, and use the size of current to control the magnetic field.

Due to the coil resistance, the size of the magnetic field is limited, with the discovery and application of superconductor, the limitation has chance to overcome. Split the first iron chip slowly with a pair of plier and a normal screwdriver, and then, you can take the chip a little hard.

After dismantling, you can find the transformer has two coils, one has thin enameled wire, and another one has thick enameled wire.

Choose the thinner one. Next, we should take the voltage into consideration. If the input voltage of the transformer is V, the output voltage is 12V, and you choose the coil with thinner enameled wire, so the voltage of your coil is V.

But, if you choose the coil with thicker enameled wire, the voltage of your coil is 12V. In fact, here is just a reference, you should choose relative voltage according to the parameter of the transformer. Reinstall the transformer, notice that reinstallation is not just like before, you should put protruding edges on the same side, instead of cross stacking like before. This is the whole guide on how to make a solenoid at home.

The materials and tools of this guide can be obtained easily. As for the electromagnetic force of the solenoid, which is decided by the current and coil turns. The bigger current, the bigger electromagnetic force; the more coil turns, the bigger electromagnetic force. Our professional team will reply to you within one business day.
