In recent years, we have observed a significant trend that brushless DC motors (BLDC) are increasingly popular in various applications such as automobiles, home appliances, power tools, and medical equipment. This phenomenon occurs due to the high-speed performance of BLDC motors, which can often exceed 10,000 rpm and even reach 100,000 rpm. At the same time, BLDC motors have low rotor inertia, allowing rapid acceleration, deceleration and reverse movement. In addition, BLDC motors have higher power density, making it easier to design more compact motor sizes. Therefore, more and more application scenarios are beginning to use BLDC motors.
- High efficiency and energy saving requirements
1) Improvement of energy efficiency standards: As the world pays increasing attention to energy efficiency, energy efficiency standards in related industries are becoming increasingly strict. For example, my country’s new national standard GB18163-2020, which will be implemented from June 1, 2021, prohibits the production and sale of motors below the IE3 energy efficiency level. This makes the market more inclined to adopt high-efficiency motor solutions, such as BLDC motors.
2) High efficiency and energy saving: Brushless motors can significantly reduce energy loss related to friction during operation, thus improving efficiency. Under the same rated power and rated speed, brushless motors are smaller, lighter and more efficient, which is in line with the global trend of energy conservation and emission reduction.
- Technological progress and cost reduction
1) Technological progress: In recent years, the optimized design of motors, the use of high-performance permanent magnet materials and innovations in drive control technology have significantly improved the performance of brushless motors and reduced manufacturing costs.
2) Cost reduction: With the expansion of production scale and the maturity of technology, the cost of control electronic equipment for brushless motors has been greatly reduced, and new control algorithms continue to emerge, further promoting the popularity of brushless motors.
- Application needs and market needs
1) Diversified application requirements: Brushless motors have the advantages of smooth operation, low noise, and long service life, and meet the high requirements for motor performance in many fields. For example, brushless motors are widely used in electric vehicles, home appliances, robotics, aerospace and other fields.
2) Market demand growth: With the rapid development of new energy vehicles, smart home and other industries, the market demand for efficient, reliable, silent motors continues to grow, providing a broad market space for the popularization of brushless motors.
- Policy promotion and environmental protection requirements
1) Policy promotion: Governments around the world have introduced policies to encourage the use of high-efficiency and energy-saving motor products and promote the upgrading of the motor industry. This contributes to the rapid development of the brushless motor market.
2) Environmental protection requirements: Brushless motors are favored by more and more consumers because they reduce mechanical friction and wear, reduce maintenance costs, reduce harmful substance emissions, and comply with environmental protection requirements.
The reason why brushless motors have gradually become mainstream is the result of technological progress, market demand, policy guidance and environmental awareness. The advantages of brushless motors such as high efficiency, energy saving, smooth operation, and long service life not only meet the high requirements for motor performance in many fields, but also conform to the global trend of energy conservation and emission reduction. With the continuous advancement of technology and the continued development of the market, brushless motors are expected to be widely used in more fields and become an important force in promoting industrial upgrading and green development.
