Who is interested in old cars?

More and more people are interested in really ancient models of cars. There is no shortage connoisseurs of such cars among the real car fans, but also a person not associated in any way with passion about cars or other vehicles also willing to peek at these cars. The car after renovation will attract the eyes of everyone in the vicinity. There is no doubt that this is a very good way to stand out in the environment around us. Although often these cars are very expensive and driving them is quite uneconomical, you can also treat it as an investment. It is true that we have obtained through this investment a quick profit, but in the long term we really expect lots of money - if not for us, if only for our children and grandchildren.


History of electric motor

Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s.2 The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Amp?re's force law, was discovered later by André-Marie Amp?re in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire.3 This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century.


Jedlik's "electromagnetic self-rotor", 1827 (Museum of Applied Arts, Budapest). The historic motor still works perfectly today.4
In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings

Less popular vehicles

The most popular when it comes to automotive, enjoy, of course, cars and motorcycles. With the increasing number of drivers also increases the number of such vehicles on our roads. However, in everyday life may be useful also other machines connected to the most popular vehicles. A good example can be here the equipment needed in agriculture, which is often not independent of the vehicle. Many agricultural machines and used in the construction industry we can associate, for example, a tractor suitable brand, which will certainly be of interest holders of such a vehicle. Of course, there is also a lot of self-propelled agricultural machines, but they are often very expensive.
