Mechanical converter

Modern man is accustomed to using electrical energy everywhere. It is hard for us to imagine the absence of electricity, on which most of our full life is based. But have you ever wondered where it comes from? What drives invisible particles, forcing them to work for the benefit of man?
The presence of an invisible force that brought certain objects into motion was still guessed by the ancient Greeks. However, the real dawn of this theme falls only on the period of industrialization of the 19th century. It was then that the famous scientist Michael Faraday discovered the phenomenon of electromagnetic induction, which explains the occurrence of an electric current in a magnetic field environment when a conductor moves in it. Today we suggest that you test this theory empirically.
The essence of the experiment is the manufacture of an electromechanical converter based on a DC motor that will rotate the magnets located in the frame of the inductance.As a result of the excitation of magnetic fields and the appearance of electromagnetic EMF at the output, we obtain an electric current. Interesting experience is also the fact that the voltage values ​​obtained will be greater than the time spent on the engine. But first things first.

Materials - Tools


  • DC motor 3 V;
  • Neodymium magnets, square 10x8 mm;
  • Steel rod section of 2-3 mm;
  • Copper wire in lacquered insulation;
  • Plastic pieces;
  • 3.7 V battery;
  • Copper wiring, shrinking;
  • Super glue.

Of the tools for the work we need: a soldering iron with solder, a lighter, a knife, pliers with pliers. The tester is needed for those who want to measure the output voltage at the converter.

From the steel rod we make two small stator frames. Pliers bend the contour, cut off the excess. The ends of the coils should also be bent (photo).

We connect the framework on superglue, and put on the middle of the heat shrink. Lighter we warm it, and thus we obtain an insulated core coil.

For winding we use thin copper wire in lacquered insulation. It must be wound on the zone of the insulator. The number of turns is 600.
Upon completion of the winding, we leave the two ends of the coil - the initial and the final. We remove the insulation, burning it with a regular cigarette lighter. This will be the stator.

On the motor shaft we sit on the superglue a pair of guides made of pieces of plastic for neodymium magnets. We place them on opposite sides of the shaft in order to increase the area of ​​contact with the magnets.

On superglue we fasten neodymium magnets to the shaft. Note that they can only connect under the condition of opposite polarities. This will be the rotor of our converter.

Two strips of thin plastic cut into the size of the engine and frame. They can be slightly bent, warming the middle of the cigarette lighter.

Glue the strips to the body of the engine. Next, we fix the frame of the stator in such a way that its open ends, without touching the magnets, are placed in the center of the rotor.

Our simple microconverter is ready. It remains to connect the engine, having soldered its ends with contacts, and to supplement the whole circuit with a battery. A standard 3.7 V lithium battery is suitable as a power supply battery.

Measurements tester show the output voltage, an order of magnitude higher than the input, which means this circuit is quite working.

Conclusion


In fairness it should be noted that electromechanical converters are a thing of the past with the advent of electronic circuits and transistors. Today, you can buy ready-made voltage boosting modules, which allow you to get high rates of about 50 V from a standard battery of 3.2 -3.7 V.
