I've always wanted to try making one of these! The force these can apply it's very impressive to me.
Will come very handy to drill plates and square tubings for future projects for sure!
I think these are called magnetic chuck, but I'll use it as a vise so to me it's an electromagnet vise.
Resin that cam be poured up to 5cm thick provided by RESIN PRO:

Index of operation and materials:
2:14 Open transofmer, cut the wels on the bottom plate with cutting disk on angle grinder
2:40 Take off the primary winding (thick wires(
3:00 Cut off secondary winding (thin wires)
3:40 Cut 50x50mm angle iron pieces with metal cutting bandsaw
4:08 Mounting tabs marked
4:15 Hole driller for nice round corner
4:37 Shaped with metal cutting band saw and 2x72 belt grinder
5:20 Box is tack welded
5:43 Two transformers are connected in series
6:40 Preparation for resin, flat surface with releasing foil and hot glue to seal edges
7:13 Specific epoxy resin that can be poured in 5cm thick layer
7:35 Black pigments added for looks
8:50 Excess transformer body is cut off now rather than earlier to avoid tearing apart the thin plates that makes these parts (if these gets damaged they tend to buzz and make weird noises)
9:18 Filling up with more regular resin to make up for previous pour shrinkage
9:40 Made flat with files
10:06 And polished up to 400 grit with orbital sander
10:26 12V 10 Amp transformer, got one fully enclosed to place inside the drill press. Some good amps are needed for the vise to hold strong
10:40 Connected to drill press switch in series after main switch so I don't forget this on
11:50 holds 80+ kgs, very happy!
Thanks a lot for watching, I hope you liked the video!

It is worth to put a diode between the +12VDC and GND in reverse direction, because when the magnets are switched off the magnetic field collapses around them and induce current which have to find a way around. If no way for the current to flow, a voltage skipe will form which can hurt the 12VDC driver circuit.

@boblewis5558 Жыл бұрын

Absolutely! The current capability of the diode MAY matter under certain circumstances but the voltage rating is of greater importance as any capacitance in the cicuit can cause ringing, hence high reverse voltage across the diode which can easily blow low voltage diodes. Choose one of over 200v rating for safety. PLENTY of FREE 1N4007 (probably the most ubiquitous rectifier diode on the planet) can be obtained off many scrap electronics boards such as PC PSUs. The 1N4007 has a MORE than ample voltage rating for the job,

@boblewis5558 Жыл бұрын

@@godparticle3833 I think you may need to do a bit more reading on magnetic cores and the saturation they experience! You get no more magnetic flux once the core becomes "saturated", hence the term and for a microwave sized transformer core it is HIGHLY doubtful you'll get much more than 100-150 amps flowing before saturation occurs. Just take a look at the size and weight of a typical MMA welding transformer to see what I mean ... Rare to find an old style transformer of that type capable of much more than about 200-250A (not without a MUCH bigger transformer)! 👎

@davidgillies620 4 жыл бұрын

I'd be cautious about that. Plunge cuts would probably be fine but side milling would be more problematical (the magnets will have much less holding capacity in shear than in the normal direction).You could certainly use it for surface grinding though as the shear forces are minimal. Most surface grinders use a mag chuck, although often of the permanent magnet type.

@E-hab 4 жыл бұрын

Unless you are talking a large chunk of steel and a tiny endmill then that would be a hard no. Milling vises exert tens of thousands of pounds of force for a reason. Mills slam carbide and high speed steel cutting edges into the part sideways like a jackhammer on meth.

I saw a video using only one transformer and 12V at about 8 amps. That's less than 100bwatts of power, but he failed to measure the breakaway force because his scale maxed out at 300kg. These things generate amazingly strong holding forces. These transformers could easily handle 1000W of input power for quite extended periods of time. Holding force should be directly proportional to current flow. Iowa, a single transformer might be able to clamp with 3000kg of force and not break a sweat.

How much current would this draw so as to use the right wire gauge, to not fry the adapter, and to estimate the magnetic flux and thus the maximum force? How do you know that the "electromagnets" will work with 6V each given that they're connected in series?

The safety warning at the start was a very good idea. High-voltage capacitors are a nightmare and they can keep a charge for a surprisingly long time (also remember the stored energy goes like the voltage squared). Back in my electronic engineering days we had a phrase: a "one-mistake power supply" as in you only got to make one mistake with it because that was all it took to kill you. As little as 11 mA across your heart ("eleven mills kills", another phrase we used) can put you into ventricular fibrillation and that's generally fatal. Apart from that, absolutely beautiful build.

I have had one of these in progress for a while. I also have a power supply for 12VDC and 10A. The circuit itself is a near-short, even with a load on the chuck were relying on the internal resistance of the wire. I’m not sure if you’ve tested this much since posting, but the design as presented is quite nice except is has a serious flaw; the heat dissipation into the copper windings and into the iron core isn’t enough if you have a long job or forget to turn it off. You risk a melt down of the wires, or a fire... hopefully the fuse blows before then. When I get a chance I will fully post my build, but if anyone else does this is strongly recommend you watch the temperature rise on the coils. Another option is to use a Car battery, but the heat also skyrockets in this near short configuration.
