To convert mechanical energy into electrical energy or vice versa, it is necessary to create a relative movement of a conductive circuit with current and magnetic field(magnet or current).IN electric machines designed for long-term operation, the rotational movement of the moving part of the machine (machine rotor) is used alternating current), located inside the stationary part (stator). The winding of the machine that serves to create a magnetic field is called an inductor, and the winding flowing around the operating current is called an armature. Both of the latter terms are also used for DC machines...

In an oscillating circuit with inductance L, capacitance C and resistance R, free electrical oscillations tend to attenuate. To prevent the oscillations from fading, it is necessary to periodically replenish the circuit with energy, then forced oscillations will arise that will not decay, because the external EMF variable will now support oscillations in the circuit.If the oscillations are supported by a source of external harmonic EMF, the frequency of which is very close to resonant frequency oscillatory circuit, then the amplitude of electrical oscillations ...

Parallel operation of transformers - connecting transformers to working together, with this connection, the winding terminals of the same name are connected to each other on the side high voltage and side winding terminals low voltage. If necessary, turn on transformers to parallel work To avoid negative consequences for the equipment, several factors must be taken into account. Let us consider in detail the inclusion conditions power transformers for parallel work. There are several groups of winding connections...

The topic of increasing energy efficiency will probably never lose its relevance. In connection with this fact, many institutes today are developing more efficient storage devices energy. And one of the promising solutions in this area seems to be the use of kinetic (in motion) energy storage devices based on highly energy-intensive flywheels.Their areas of application can extend from small autonomous sources uninterruptible power supply for private households to large industrial installations that accumulate energy during the rotation of the flywheel...

Speaking about magnetic bearings or contactless suspensions, one cannot fail to note their remarkable qualities: no lubrication is needed, there are no rubbing parts, therefore there are no friction losses, extremely low level vibration, high relative speed, low power consumption, system automatic control and monitoring the condition of bearings, the possibility of sealing. All these advantages make magnetic bearings the best solutions for many applications: for gas turbines, for cryogenic technology, in high-speed electric generators, for vacuum devices...

Real electrical circuits most often include not one conductor, but several conductors somehow connected to each other. In the very in simple form an electrical circuit has only an “input” and an “output,” that is, two terminals for connection with other conductors through which charge (current) can flow into the circuit and flow out of the circuit. With a steady current in the circuit, the values ​​of the currents at the input and output will be the same.If you look at electrical circuit, which includes several different conductors, and consider a couple of points on it (entrance and exit)...

The transformation ratio is the ratio of the voltage at the ends of the primary winding of the transformer to the voltage at the terminals of its secondary winding, determined at no-load (when there are several secondary windings, then there are also several coefficients, they are determined in this case one by one). This ratio is taken to be equal to the ratio of the numbers of turns in the corresponding windings.The value of the transformation ratio is easily calculated by dividingindicators of the EMF of the windings of the transformer under study: EMF of the primary winding - on EMF secondary ...

Nikola Tesla (07/10/1856 - 01/07/1943) is one of the largest figures in the field of electrical and radio engineering. His work on the creation of a multiphase electric motor and on high voltage currents and high frequency had a huge impact on technical progress and were the basis for the emergence of entire branches of the electrical industry.Nikola Tesla was born on July 10, 1856 in the family of a priest in the Serbian village of Smilyan, not far from Adriatic coast. After graduating from real school, Tesla successfully graduated from the Higher Technical School in Graz...

If a person in a state of mental and physical rest applies electrodes to his head and connects them to a recording device through an amplifier, then electrical vibrations can be detected. These vibrations arise in the cerebral cortex and are associated with special nervous activity. They are also recorded directly from the brain when the skull is opened during surgery. The presence of rhythmic, spontaneously occurring electrical oscillations in the brain was established in 1875 by the Russian physiologist V. Ya. Danilevsky and the English scientist Richard Cato by experimenting on animals...

Power transformers are integral elements of the power system. These elements perform very important function- they convert electricity from one voltage value to another value necessary for further energy transfer or for powering end consumers. The most important task of energy is maintaining normal and uninterrupted operation operation of equipment, including power transformers, which can only be ensured if it is used correctly. In this article we will consider in detail the operating features...
