How to make an induction cooker with your own hands



How to make fried eggs using magnets and an electric motor? Having made an induction furnace from these materials. And how to do this, let's try to deal with the master. The master did not set himself the goal of making a beautiful slab, but rather a textbook. But this does not mean that the stove is not functional.

Tools and materials:
-Neodymium magnets;
-Electric motor;
-Plywood;
-Board;
-Hacksaw;
-Fasteners;
-Plexiglass;
-A screwdriver;

Step One: Magnets
The master, on a template, fixes neodymium magnets on a plywood disk. Magnets need to be installed alternating, polarity. In the center of the disk you need cuts a hole for the motor shaft.

Step Two: Engine
In the countertop cuts the same hole as in the disk. Secures the engine under the countertop. The engine master took from the treadmill. The engine is connected via a speed control.




Step Three: Cooker
Fastens a disk with magnets on a motor shaft. The disc should rotate freely without clinging to the countertops.

On the supports sets a sheet of plexiglass. Plexiglass should be as close to the magnets as possible.


Step Four: Testing
Now it's time to test the operation of the induction furnace. The master turns on the engine and spins it up to 1600 rpm. He puts the pan on the stove and measures the temperature.

The pan warmed up to 49 ° C. Then the master adds one more magnet to the second tier.

In this case, it was possible to heat the surface of the pan to 104-115 degrees. It is possible to fry fried eggs or boil water.

Unlike induction cookers sold in stores where only utensils with a high percentage of iron can be used, this stove can be cooked in both aluminum and copper utensils.

You can see how the author makes and tests the furnace in the video below.

Here is the response of the author of the project, "We used it only to show the rotating magnets below. The plexiglass itself does not heat up from the magnets, but the pan sitting on the plexiglass really made the plexiglass deformed a little when we finished!"
And why does he have a frying pan, plexiglass does not melt ???
The problem is that magnets do not like high temperatures, this is death for them - they are demagnetized. But the idea suggests that installation on this principle can be done without magnets.
even in pans and pans they put this icon
Yes, I love raw eggs with salt and seasoning. Shake and dip bread - an incredible buzz!
And the stove is cool.
electric motor with shorted windings - you twist him, he warms up, just take off the heat
Why shoot? You will sweat! smile
Yeah, literally, yes, fun. Of course, I did not mean eggs, but the generation of heat as an idea - to heat the coolant in his house, in the house! And then, why upstairs? It is not difficult to transfer the torque down - the bar, cable, through the roof of the kitchen ... In many ways, does the Joule mixer device look like, is it only the heat generated through the forces of "viscous friction"? What is more effective is a question. There is also a curious patentik, a converter of mechanical energy into heat - an electric motor with shorted windings - you twist it, it heats up, just take off the heat. With all the comic, it seems the device has a good efficiency.
in generating heat by a windmill.
Very imaginatively imagined himself sitting on top of a mast of a windmill, with a frying pan in one hand, an egg in the other, and solving a non-trivial task: how to break an egg into a frying pan and not rattle down! How I got there is a separate issue! xaxa
Well, moody power electronics available - motor speed control. Without it, it is hand-operated. Campaign option. Here, it's just an interesting experiment that can find application, say, in the generation of heat by a windmill.
In theory, the Foucault currents, due to which the piece of iron is heated, should be larger in more massive dishes.
Some individuals of humanity do not fry eggs at all, but eat them raw
Well, they really need such a stove! smile
This is what I understand - an induction cooker without capricious power electronics.
And why is this all?

Mankind knows many simpler ways to fry an egg! smile
