Yes, I'm familiar with handedness. The standardized push solenoids I've found are either too big or too expensive. This is why I came up with the design for the push EM. I have been able to locate this:http://www.magnetechcorp.com/push-pull.html which again, is too expensive but they may be...
Thanks. Interesting.
So you're saying at these low power levels it may not matter which method it's wound? The leads may need to be both on one end. Either method would allow that configuration as it's just a matter of when to stop winding, no? If not, then what you're suggesting is if method...
I have a small but urgent electromagnet project in process however the actuator I need doesn't seem to be readily available although although it's not anything new, except for the custom size I need. Attached is a reference sketch.
I ordered and received these 12mm OD buzzers 12mm WST-1212S...
Thanks for the wire chart, very helpful.
I'm back to current being about amps, not voltage, which is correct. It seems the goal is to maximize the amperage without overheating the coil wires.
The EMs will be used as a "grabber" on underwater iron based mineral structures to "walk" the sub in...
Also, to give a better idea of size now, starting from the inside-out, the core might need to be between 1/16" to 1/18" diameter x 3/8" to 1/2" long. The maximum diameter would ideally be 1/4" max. So I need to get as many turns of wire around the core as possible.
Also, if I keep the winding...
Thanks for the reply.
Since EMs are pretty basic devices, once we know the parameters, it would be easier and less expensive to make them because they will be fitting into another custom shaped device. So I'm trying to get the fundamentals clarified before moving ahead.
The power source will...
We need to create a remote controlled electromagnet for the pick-up arm of the submarine we're working on. EMs are pretty simple devices but I need some help to clarify a couple issues. The EMs in mind will be 1" or less in size and won't use more than 24Volts but 12Volts or less is more likely...
Those are excellent suggestions and questions. The transmotec sample should be a good starting point to test with. Thanks.
I've been somewhat general because I know the device needs to be tested and I don't want to take more of your time than is necessary until I know specifically what's...
Well, it would return to it's original shape, defining it as a fluid but after a long time. It needs to have a much higher flow rate (not clay or putty-like) where it would return to it's relaxed state as in its original form immediately after impact pressure.
I'll see what I can find under...
Thanks for the replies.
It would be a solenoid with a moving armature. The "rod" in my question is the armature.
It being a device with moving parts, I posted the question here. Is it more appropriate to be in the magnetic forum?

I've been searching unsuccessfully for an electromagnet for my application and unless anyone can provide a source lead, I'll try to make one myself. I need some guidance for the parameters I need to say within so I don't waste time.
It needs to be small, say no more than 1" long by 3/8" dia...
I think that won't work since it won't return to its original shape afterwards. Plus I don't think it will become rigid enough.
Thanks for the suggestion.

Hello,
We're working on an application which we believe the behavior of a non-Newtonian fluid which becomes rigid when under stress. It needs to be inorganic so it won't spoil and as I understand it there are silicone polymers or oils which meet this criteria. Any other such fluid would be good...
Thanks. They may be a good lead for needed components but the subs they seem to specialize in are very different from the direction we're going.

Thanks again. I'm going to look into the Turnigy 130A and see how it works.
Although they will be drifting at times, preparing for continuous operation will take care of both scenarios. Following you advice, we'll need to add some kind of sealed heat exchanging system to it. I don't think that...
