What is the function of the controller?
The controller refers to the master device that controls the starting, speed regulating, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and the resistance value in the special transformer circuit in a predetermined sequence. It is composed of program counter, instruction register, instruction decoder, Electronic Metal, timing generator and operation controller. It is the "decision-making body" that issues commands, that is, to coordinate and command the operation of the whole computer system.
Generally speaking, only when the controller is well protected can the computer run smoothly.
To properly protect the controller, you will need to customize a enclosure for it in equipment cabinet. Customized materials for the enclosure range from acrylic, glass, ABS, steel to aluminum and aluminum alloy. Such as communication equipment What kind of material should we choose as the most suitable controller enclosure? YONGU will give you an analysis.
Acrylic, high weather resistance, but there are toxic gases such as formaldehyde; The glass has good light transmission, but is not heat-resistant; ABS has good dyeing property but low dielectric strength; Steel has high strength, but it is easy to rust... Considering various factors and supported by relevant data, we come to the following conclusion: aluminum alloy material is a relatively correct choice for controller enclosure customization.
Why can aluminum alloy enclosure become a popular enclosure material——
1. Strong corrosion resistance and long service life. The surface of aluminum alloy is easy to form a solid oxide film, which can be used in a humid environment for a long time. Corrosion due to environmental factors is rare.
2. Good plasticity. Since the density of aluminum alloy is small, it can be processed into various shapes. In addition, even if the surface is damaged, it can be repaired quickly.
3. Light weight and strong convenience. As a enclosure, the weight of aluminum alloy is only one tenth of that of cast iron, which greatly saves manpower and material resources during use and transportation, saves transportation costs, reduces labor intensity and saves assembly time.
4. High safety performance and high pressure. Because the strength and stiffness of aluminum alloy are much higher than that of copper, it can withstand a series of external forces such as large pressure, bending force, tensile force and impact force even when the enclosure is relatively weak, so as to truly protect the internal devices.
5. Low use cost, energy saving and consumption reduction. Due to its excellent performance, the service life of aluminum alloy is relatively long compared with other materials, which greatly reduces the use cost.
In conclusion, it is a wise choice to choose aluminum alloy as the customized material for the controller enclosure.
