AWAIBA electrical components Germany AWAIBA model AWAIBA price

AWAIBA electrical components are devices that convert electrical energy into mechanical energy. They utilize energized coils (i.e., stator windings) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to produce electromagnetic rotational torque. Electric motors are classified into DC motors and AC motors based on the power supply used. Most motors in power systems are AC motors, which can be synchronous or asynchronous (where the stator magnetic field speed does not remain synchronized with the rotor rotation speed). The motor mainly consists of a stator and a rotor. The direction of motion of current-carrying conductors under force in a magnetic field is related to the direction of the current and the magnetic flux lines (magnetic field direction). The working principle of an electric motor is the force exerted by the magnetic field on the current, causing the motor to rotate.

AWAIBA electrical component features

1. High sensitivity; 2. Geometric shape has multi-faceted adaptability, allowing fiber optic sensors to be made in arbitrary shapes; 3. Can manufacture devices for sensing various physical information (sound, magnetism, temperature, rotation, etc.); 4. Can be used in high voltage, electrical noise, high temperature, corrosion, or other harsh environments; 9. And has inherent compatibility with fiber optic telemetry technology. The advantages of fiber optic sensors compared to traditional sensors are that they use light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information, possessing the characteristics of fiber optics and optical measurement, with a series of unique advantages. Good electrical insulation performance, strong anti-electromagnetic interference capability, non-intrusive, high sensitivity, easy to realize long-distance monitoring of measured signals, corrosion resistance, explosion-proof, flexible optical path, and convenient connection to computers. Sensors are developing towards sensitivity, precision, strong adaptability, compactness, and intelligence. They can serve as human eyes and ears in places inaccessible to humans (such as high-temperature areas or areas harmful to humans, such as nuclear radiation zones), and can even surpass human physiological limits to receive external information imperceptible to human senses.

AWAIBA electrical component characteristics

So-called dynamic characteristics refer to the output characteristics of a sensor when the input changes. In practical work, the dynamic characteristics of a sensor are often expressed by its response to certain standard input signals. This is because the sensor's response to standard input signals is easily obtained by experimental methods, and there is a certain relationship between its response to standard input signals and its response to arbitrary input signals; often, knowing the former allows deduction of the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also often expressed by step response and frequency response.

AWAIBA electrical component principle

A Schottky diode is a metal-semiconductor device made using noble metals (gold, silver, aluminum, platinum, etc.) A as the anode and N-type semiconductor B as the cathode, utilizing the rectifying characteristics of the barrier formed at their contact surface. Because there are a large number of electrons in the N-type semiconductor and only a very small number of free electrons in the noble metal, electrons diffuse from the high-concentration B to the low-concentration A. Obviously, there are no holes in the metal A, so there is no diffusion movement of holes from A to B. As electrons continuously diffuse from B to A, the electron concentration on the surface of B gradually decreases, destroying surface electrical neutrality, thus forming a barrier whose electric field direction is B → A. However, under the action of this electric field, electrons in A also produce a drift movement from A → B, thereby weakening the electric field formed by the diffusion movement. After a space charge region of a certain width is established, the electron drift movement caused by the electric field and the electron diffusion movement caused by the concentration difference reach relative equilibrium, forming the Schottky barrier. The internal circuit structure of a typical Schottky rectifier uses N-type semiconductor as the substrate, on which an N-epitaxial layer doped with arsenic is formed. The anode uses materials such as molybdenum or aluminum to form a barrier layer. Silicon dioxide is used to eliminate the electric field in the edge region, increasing the withstand voltage of the tube. The N-type substrate has a very small on-state resistance, and its doping concentration is 106% times higher than that of the H-layer. An N+ cathode layer is formed under the substrate to reduce the contact resistance of the cathode. By adjusting structural parameters, a Schottky barrier is formed between the N-type substrate and the anode metal.
