Icar electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage and low-voltage types based on their application range; the boundary between high and low voltage is somewhat ambiguous, but generally, equipment above 3kV is referred to as high-voltage apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They automatically disconnect the circuit in the event of severe faults such as overload, short circuit, or undervoltage. Their function is equivalent to a combination of fuse switches and over/under thermal relays. Moreover, component replacement is generally not required after interrupting fault currents. They have been widely applied. In the generation, transmission, and use of electricity, power distribution is an extremely important link. The distribution system includes transformers and various high- and low-voltage electrical equipment, with low-voltage circuit breakers being a widely used type of electrical apparatus.

Icar electrical component classification

Based on the type of power supply for the motor, motors can be divided into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. According to structure and working principle, motors can be classified into DC motors, asynchronous motors, and synchronous motors. Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors. AC commutator motors are further divided into single-phase series-wound motors, universal AC/DC motors, and repulsion motors. According to starting and operating methods, motors can be classified into capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors. According to application, motors can be divided into drive motors and control motors. Drive motors are further divided into motors for power tools, motors for home appliances, and motors for other general small mechanical equipment. Control motors are further divided into stepper motors and servo motors. According to rotor structure, motors can be divided into squirrel-cage induction motors and wound-rotor induction motors. According to operating speed, motors can be classified into high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors.

Icar electrical component types

Inductors can be made by winding conductive material, typically copper wire, around a magnetic core; alternatively, the core can be removed or replaced with a ferromagnetic material. Core materials with higher permeability than air can confine the magnetic field more tightly around the inductor component, thereby increasing inductance. There are many types of inductors; most are made with an outer enamel-coated coil wound around a ferrite bobbin, while some shielded inductors place the coil entirely within the ferrite. The cores of some inductor components are adjustable, allowing the inductance value to be changed. Small inductors can be directly etched onto PCB boards using a method that lays out a spiral trace. Low-value inductors can also be fabricated in integrated circuits using the same processes used for manufacturing transistors. In these applications, aluminum interconnects are often used as the conductive material. Regardless of the method, due to practical constraints, the most commonly used approach is a circuit called a "gyrator," which uses a capacitor and active components to exhibit the same characteristics as an inductor component. Inductor components used for blocking high frequencies are often constructed from a metal wire passing through a magnetic post or bead.

Icar electrical component structure

1. LCD Panel: The LCD panel includes a polarizing film, glass substrates, black matrix, color filters, protective film, common electrodes, alignment layer, liquid crystal layer (liquid crystal, spacers, sealant), capacitors, display electrodes, prism layer, and diffusion layer. The polarizing film, also known as a polarizer, is divided into an upper polarizer and a lower polarizer. The polarization functions of the upper and lower polarizers are perpendicular to each other. They act like a fence, blocking light wave components as required; for example, they block light wave components perpendicular to the polarizer fence and only allow light wave components parallel to the fence to pass through. 2. Glass Substrate: In liquid crystal displays, glass substrates are divided into an upper substrate and a lower substrate. Their main function is to hold the liquid crystal material in the space between the two substrates. The material for glass substrates is generally alkali-free borosilicate glass with excellent mechanical properties, heat resistance, and chemical corrosion resistance. For TFT-LCD, one glass substrate is distributed with TFT, while the other glass substrate is deposited with color filters. 3. Black Matrix: The black matrix uses highly light-blocking materials to separate the red, green, and blue primary colors in the color filter (to prevent color mixing) and to prevent light leakage, thereby helping to improve the contrast of each color block. Additionally, in TFT-LCD, the black matrix can conceal internal electrode wiring or thin-film transistors. Color filters, also known as color filter films, function to produce the 3 primary colors of red, green, and blue, enabling full-color display on the liquid crystal display. 4. Alignment Film: The alignment film, also known as an orientation film or directional layer, functions to achieve uniform arrangement and orientation of liquid crystal molecules at the microscopic level. 5. Transparent Electrodes: Transparent electrodes are divided into common electrodes and pixel electrodes. The input signal voltage is applied between the pixel electrode and the common electrode. Transparent electrodes are typically formed by depositing indium tin oxide (ITO) material on the glass substrate to create a transparent conductive layer. 6. Liquid Crystal Material: In LCD, the liquid crystal material acts like a light valve, controlling the brightness of transmitted light to achieve information display. 7. Driver IC: The driver IC is essentially a set of integrated circuit chip devices used to adjust and control the phase, peak value, frequency, etc., of the potential signals on the transparent electrodes, establishing a driving electric field to ultimately realize information display on the liquid crystal. In the LCD panel, active-matrix liquid crystal displays are constructed by sealing twisted nematic (TN) liquid crystal material between two glass substrates. The upper glass substrate, closer to the display screen, is deposited with red, green, and blue (RGB) tricolor filters (also known as color filter films), a black matrix, and a common transparent electrode. The lower glass substrate (the substrate farther from the display screen) is equipped with thin-film transistor (TFT) devices, transparent pixel electrodes, storage capacitors, gate lines, signal lines, etc. Alignment films (also known as alignment layers) are prepared on the inner sides of the two glass substrates to orient the liquid crystal molecules. Liquid crystal material is injected between the two glass substrates, and spacers are dispersed to ensure uniform gap thickness. The periphery is bonded with frame sealant to provide sealing, and the common electrodes of the upper and lower glass substrates are connected using silver dot adhesive technology. Polarizers (also known as polarizing films) are attached to the outer sides of the upper and lower glass substrates, respectively. When a voltage is applied between the pixel transparent electrode and the common transparent electrode, the alignment state of the liquid crystal molecules changes. Consequently, the intensity of incident light passing through the liquid crystal also changes. Liquid crystal displays utilize the optical rotation property of the liquid crystal material combined with electric field control to achieve information display. 8. Backlight Module: LCD products are non-emissive electronic devices that do not possess inherent light-emitting properties. They rely on light emission from the source in the backlight module to achieve display performance; therefore, the brightness of LCD is determined by its backlight module. Thus, the performance of the backlight module directly affects the display quality of the LCD panel. The backlight module includes illumination sources, reflectors, light guide plates, diffusion sheets, brightness enhancement films (prism sheets), and frames. Backlight modules used in LCD can be mainly divided into two categories: edge-lit backlight modules and direct-lit backlight modules. Mobile phones, laptops, and monitors (15 inches) mainly use edge-lit backlight modules, while LCD TVs mostly use direct-lit backlight module light sources. Cold cathode fluorescent lamps and light-emitting diodes are the primary backlight sources for LCD. 9. Reflector: The reflector, also known as a reflection cover, mainly functions to direct all light emitted by the source into the light guide plate, minimizing unnecessary loss as much as possible. 1. Light Guide Plate: The main function of the light guide plate is to guide light from the side-mounted source toward the front of the panel. 11. Prism Sheet: The prism sheet, also known as a brightness enhancement film, mainly functions to concentrate scattered light through refraction and total internal reflection within the film layer, directing it at specific angles out from the backlight source to achieve a screen brightening effect.14. Diffuser sheet: The main function of the diffuser sheet is to correct the edge-lit light from the backlight module into a uniform surface light source to achieve optical diffusion. Diffuser sheets are divided into upper and lower diffuser sheets. The upper diffuser sheet is located between the prism sheet and the LCD assembly, closer to the display panel. The lower diffuser sheet is located between the light guide plate and the prism sheet, closer to the backlight source.
