103016753 electrical components are indispensable measuring instruments for departments such as power electronics, generally aimed at measuring voltage, current, and resistance. Multimeters are classified into analog multimeters and digital multimeters based on the display method. They are multifunctional, multi-range measuring instruments. General multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels; some can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as β). A multimeter is a magnetoelectric instrument equipped with a rectifier, capable of measuring various electrical parameters such as AC/DC current, voltage, and resistance. For each electrical quantity, there are generally several ranges. Also known as a multitester or simply multimeter. A multimeter consists of a magnetoelectric ammeter (meter head), measuring circuit, and selector switch. By changing the selector switch, various electrical parameters can be measured conveniently. The main basis for its circuit calculation is Ohm's law for closed circuits. There are many types of multimeters, which should be selected according to different requirements during use.

103016753 electrical component principles

A Schottky diode is a metal-semiconductor device made by 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 hole diffusion movement 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 a relative balance, forming a 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 100% 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.

103016753 electrical component classification

Based on the working power supply of the motor, it can be divided into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. Motors can be divided into DC motors, asynchronous motors, and synchronous motors based on structure and working principle. 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, etc. Phase asynchronous motors and shaded-pole asynchronous motors, etc. AC commutator motors are further divided into single-phase series-wound motors, AC/DC universal motors, and repulsion motors. Motors can be divided 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 based on starting and running methods. Motors can be divided into drive motors and control motors based on usage. 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, etc. Motors can be divided into cage-type induction motors and wound-rotor induction motors based on rotor structure. Motors can be divided into high-speed motors, low-speed motors, constant-speed motors, and adjustable-speed motors based on operating speed.
