Avemis electrical components Germany Avemis model Avemis price

Avemis electrical components refer to devices that convert chemical energy into electrical energy, consisting of a cup, tank, or other container or part of the space of a composite container holding an electrolyte solution and metal electrodes to generate current. They have positive and negative terminals. With technological advancements, batteries generally refer to small devices capable of generating electrical energy, such as solar cells. The main performance parameters of batteries include electromotive force, capacity, specific energy, and resistance. Using batteries as an energy source provides stable voltage, stable current, long-term stable power supply, and current minimally affected by external factors. Furthermore, batteries have a simple structure, are portable, offer easy charging and discharging operations, are unaffected by external climate and temperature, and provide stable and reliable performance, playing a significant role in various aspects of modern social life.

Avemis electrical component structure

Inductors are generally composed of a bobbin, winding, shield, encapsulation material, magnetic core, or iron core. 1, Bobbin: The bobbin refers to the support for winding the coil. For larger fixed inductors or adjustable inductors (such as oscillator coils, choke coils, etc.), enameled wire (or silk-covered wire) is mostly wound around the bobbin, and then a magnetic core, copper core, or iron core is inserted into the inner cavity of the bobbin to increase inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be shaped according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins but wind the enameled wire directly onto the magnetic core. Air-core inductors (also known as formless coils or air coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shields; instead, they are wound on a mold which is then removed, leaving a certain distance between the coil turns. 2, Winding: The winding refers to a set of coils with specified functions and is the basic component of an inductor. Windings are classified into single-layer and multi-layer types. Single-layer windings come in two forms: close-wound (where wires are wound turn by turn adjacent to each other) and spaced-wound (where a certain distance is maintained between each turn). Multi-layer windings include layered flat winding, random winding, honeycomb winding, and others. 3, Magnetic Core and Magnetic Rod: Magnetic cores and rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite. They come in various shapes such as "I" shape, cylindrical, cap shape, "E" shape, and pot core shape. 4, Iron Core: Iron core materials mainly include silicon steel sheets and permalloy, mostly in "E" shape. 5, Shield: To prevent the magnetic field generated by some inductors during operation from affecting other circuits and components, a metal shield is added (such as for oscillator coils in semiconductor radios). Inductors with shields experience increased coil losses, resulting in a lower Q value. 12, Encapsulation Material: Some inductors (such as color-coded inductors and color-ring inductors) are sealed with encapsulation materials after winding. Encapsulation materials include plastic or epoxy resin.

Avemis electrical component principle

Inductance is the ratio of the magnetic flux in a conductor to the current producing this flux when alternating current passes through the conductor, generating alternating magnetic flux inside and around it. When direct current passes through an inductor, only fixed magnetic lines of force appear around it, unchanged over time. However, when alternating current passes through the coil, magnetic lines of force changing with time appear around it. Analyzing based on Faraday's law of electromagnetic induction (magnetism generating electricity), changing magnetic lines of force produce an induced electromotive force at both ends of the coil, equivalent to a "new power source." When a closed loop is formed, this induced electromotive force generates an induced current. According to Lenz's law, the total magnetic lines of force produced by the induced current attempt to oppose the change in the original magnetic lines of force. Since the change in the original magnetic lines of force originates from the changes in the external alternating power source, objectively, the inductor coil has the characteristic of opposing changes in current in an AC circuit. The inductor coil has characteristics similar to inertia in mechanics, named "self-induction" in electrical engineering. Sparks often occur at the instant of opening or closing a knife switch, caused by the high induced electromotive force generated by self-induction.
