Mechanical converter

The modern man has got used to use electric 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 thought about where it comes from? What drives invisible particles, forcing them to work for the benefit of man? The presence of an invisible force that set certain objects in motion was still guessed by the ancient Greeks. However, the real dawn of this topic is only for the period of industrialization of the 19th century. It was then that the famous scientist Michael Faraday discovers the phenomenon of electromagnetic induction, which explains the occurrence of an electric current in a magnetic field environment when the 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, which will rotate the magnets that are in the frame of the inductor coil.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 everything is in order.

Materials - Tools

  • 3 V DC motor;
  • Neodymium magnets, square 10x8 mm;
  • Steel bar with a section of 2-3 mm;
  • Copper wire in lacquered insulation;
  • Plastic pieces;
  • 3.7V battery;
  • Copper wiring, shrinkable;
  • Superglue.
Of the tools for the job we need: a soldering iron with solder, a lighter, a knife, pliers with pliers. The tester will be needed for those who want to measure the output voltage on the converter.

Putting together an electromechanical voltage converter

Making a steel bar, we make two small frames stator, we cut the contour with the help of pliers, we cut off the excess, the ends of the coils should also be bent (photo). Mechanical converter of electrical energy

For the winding we use thin copper wire in lacquered insulation. It must be wound on the zone of the insulator. Number of turns - 600. At the end of the winding we leave the two ends of the coil - the initial and the final. We remove the insulation, burning it with a conventional lighter. This will be the stator.

On the motor shaft, sit on the superglue with a pair of plastic pieces for neodymium magnets. We arrange them on opposite sides of the shaft to increase the area of ​​contact with the magnets.

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

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

Our simplest micro-converter is ready. It remains to connect the engine, having soldered its ends with contacts, and to supplement the whole circuit with a battery.An ordinary lithium battery from a 3.7V laptop will work as a power supply battery.

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

Conclusion

In fairness It is worth noting that electromechanical converters are a thing of the past with the advent of electronic chips 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.
