ZAMEL electrical components are switches controlled by electromagnets, that is, a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, causing the movable iron core to push or pull the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries, most commonly as contactors in the industrial sector. An electromagnetic switch is the control switch on a starter motor and is one of the three major components of a starter motor (DC motor, transmission engagement mechanism, electromagnetic switch). Its working principle is that the coil generates electromagnetic attraction when energized, causing the movable iron core to move, thereby on one hand pulling the transmission engagement mechanism to move the starter pinion forward to engage with the engine flywheel ring gear, and on the other hand pushing the switch contacts to connect, causing the DC motor to be energized and operate, thereby driving the engine to start.

ZAMEL electrical component classification

Microphones can be classified into dynamic microphones and condenser microphones based on their transduction principles. Dynamic types can be further subdivided into moving-coil microphones and ribbon microphones. Common commercial microphone types include condenser microphones, crystal microphones, carbon microphones, and dynamic microphones. Common condenser microphones use two types of energy sources: DC bias power supplies and electret films. Both these condenser microphones and crystal microphones convert acoustic energy into electrical energy, generating a changing electric field. Carbon microphones use a DC voltage source and change their resistance through sound vibration, thereby converting acoustic signals into electrical signals. Condenser, crystal, and carbon microphones all generate a voltage signal proportional to the displacement of the sensitive diaphragm, while dynamic microphones generate a voltage signal proportional to the vibration velocity of the sensitive diaphragm. Dynamic microphones use permanent magnets as an energy source and convert acoustic energy into electrical energy based on the inductive effect.

1, classified by operating nature, can be divided into transmitting antennas and receiving antennas. 2, classified by purpose, can be divided into communication antennas, broadcast antennas, television antennas, radar antennas, etc. 3, classified by directionality, can be divided into omnidirectional antennas and directional antennas, etc. 4, classified by operating wavelength, can be divided into ultra-long wave antennas, long wave antennas, medium wave antennas, short wave antennas, ultra-short wave antennas, microwave antennas, etc. 5, classified by structural form and working principle, can be divided into wire antennas and aperture antennas, etc. Characteristic parameters describing antennas include radiation pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization, and bandwidth. 6, classified by dimension, can be divided into two types: (1) One-dimensional antennas consist of many wires, which are either straight lines like those used in mobile phones, or some clever shapes, like the old rabbit ears used on televisions before the advent of cable TV. Monopole and dipole antennas are the two most basic one-dimensional antennas. (2) Two-dimensional antennas: diverse variations, including patch type (a square piece of metal), array type (a bundle of patches organized in a two-dimensional pattern), horn type, and dish type. 9, antennas can be divided into three major categories based on usage scenarios: handheld transceiver antennas, vehicle-mounted antennas, and base station antennas. Handheld transceiver antennas: these are antennas for personal use with handheld walkie-talkies, commonly divided into rubber antennas and telescopic antennas. Vehicle-mounted antennas: these refer to communication antennas originally designed for installation on vehicles, with suction cup antennas being the most common and widely used. Vehicle-mounted antenna structures also include shortened types, quarter-wavelength, center-loaded, five-eighths wavelength, and half-wave dipole types. Base station antennas: play a very critical role in the entire communication system, especially as communication hubs at base stations. Commonly used base station antennas include fiberglass high-gain antennas, four-element array antennas (eight-element array antennas), and directional antennas

ZAMEL electrical component principles

The working principle of a discharge tube is gas gap discharge i When a certain voltage is applied between the two poles of the discharge tube, a non-uniform electric field is generated between the poles: under the action of this electric field, the gas inside the tube begins to ionize. When the external voltage increases to the point where the field strength between the poles exceeds the insulation strength of the gas, the gap between the two poles will break down and discharge, transforming from an original insulating state to a conductive state. After conduction, the voltage between the two poles of the discharge tube is maintained at the residual voltage level determined by the discharge arc channel. This residual voltage is generally very low, thereby protecting electronic equipment connected in parallel with the discharge tube from overvoltage damage.
