Revolutionizing Cooling: Unleashing the Power of DC Brushless Fan

Einführung

Welcome to the world of advanced cooling technology, today we will explore the miracle of DC brushless fan 12V 40mm! This article will take you deeper into this innovative fan, which has played an important role in cooling systems in various industries. Unlike traditional fans that rely on brush driven motors, DC brushless fan 12V 40mm uses electronic control commutation to eliminate wear caused by brushes. The advancement of this technology has significantly improved the efficiency, noise level, and lifespan of DC brushless fans, making them the preferred choice for many cooling applications. Let’s delve deeper into the internal structure of this revolutionary fan and explore how it redefines cooling solutions for various applications. Ready to be amazed by the excellent performance of the DC brushless fan, let’s enter the eye-catching features and application fields of this fan together.

Structure

It can be mainly divided into four main parts: rotor, stator, outer frame, motor (motor), as well as some other fragmented components.

1. The fan rotor part:
   It includes fan blades, which are the core of generating air flow and the axis of Computer fan, and are used to support the balance of fan blade rolling, rotor magnetic ring, permanent magnet, key to promote the switching speed of magnetic stage, outer frame of magnetic ring, and fixed magnetic ring.
2. The stator part of the fan:
   Including supporting springs, separating bearings to balance the shaft center and bearings, providing high speed, low friction, long life rotation, retaining rings, fixed and combined rotation of the entire component and motor part, production rotation direction, dynamic size, and rotation speed are key.
3. The outer frame of Computer fan:
   It supports the fan motor and serves as a guide.
4. The fan motor part:
   Including circuit boards, controlling energy consumption and signal entry and exit, magnetic stage propulsion switching generated by silicon steel sheets (i.e. stator magnets with attached winding coils), upper and lower covers of silicon steel sheets, fixing and insulation.

Characteristics

• Energy efficient: DC brushless fan 12V 40mm is known for their excellent energy efficiency. Compared to conventional fans, it achieves precise speed control through an electronic phase change system, which reduces energy consumption. This efficient capability not only helps reduce energy bills, but also has a positive impact on the environment, reducing carbon emissions and contributing to sustainable development.
• Intelligent Control: The electronic control system of the brushless DC fan gives it an intelligent character. Utilising advanced temperature and speed sensing technology, these fans automatically adjust their speed in response to real-time environmental changes, maintaining just the right temperature and ventilation. In addition, some DC brushless fans support remote control and smart connectivity, allowing users to easily operate and customise fan settings remotely from their smartphones or other devices.
• Application Expansion: As technology continues to advance, brushless DC fans are expanding in application areas. In addition to the common electronic equipment cooling, automotive air conditioning and industrial ventilation, it is also widely used in emerging areas, such as smart homes, Internet of Things devices, artificial intelligence systems and so on. Its high efficiency and intelligent characteristics provide strong support for the performance improvement of the new generation of technology products.

Vorteile

The core of DC brushless fan 12V 40mm is brushless motors, which have advantages over traditional brushless motors due to their small size, high efficiency, and long lifespan.

1. Small volume
   Optimize the design and copper wire selection to improve slot filling rate, strengthen heat dissipation, improve motor efficiency, and reduce motor volume. Compared with a brushless motor with a 200W fan, the height of the motor was reduced from 88.2mm to 68.5mm with the same outer diameter, making it more user-friendly for the overall spatial layout of the vehicle. The currently developed 400W brushless motor can achieve a thinnest thickness of 63mm.
2. High efficiency
   The motor is the most energy-efficient part of the entire electromechanical system, so improving its work efficiency is even more important. For a single motor, the efficiency with brushes is around 65%, while our 400W brushless motor has an efficiency of up to 85%, which is a 20% increase in motor efficiency compared to the previous one.
3. Long lifespan
   Brushless fan motor eliminates the friction between carbon brushes and commutators, and only the bearings of the motor are worn, greatly improving its lifespan. Under comprehensive working conditions, the lifespan of the motor can reach 30000 hours, which is about three times that of a brush motor. Remark: instead of Hall sensor measurement, the Counter-electromotive force method is used to check the side position.
