At the recent leaders’ climate summit, President Xi Jinping delivered an important speech, mentioning China’s efforts to achieve carbon peaks by 2030 and carbon neutrality by 2060, and initiated green initiatives.
Carbon neutrality, a term for energy saving and emission reduction, a means to reduce carbon dioxide emissions. It refers to the total amount of greenhouse gas emissions produced directly or indirectly generated by enterprises, groups or individuals within a certain period of time, and through afforestation, energy conservation and emission reduction, etc., offset their own carbon dioxide emissions and achieve "zero emissions" of carbon dioxide.
Carbon peak refers to the steady decline of carbon emissions after entering the plateau period.
According to statistics, the national carbon emissions in 2019 are about 11.5 billion tons of carbon dioxide equivalent, ranking first in the world. It is about 5.8 billion tons in the United States and 2-3 times that of the 3.5 billion tons in Europe. The pressure to reduce emissions is greater than that of developed countries. China has promised The time from peaking carbon to carbon neutrality is far shorter than that of developed countries, which means that enterprises and organizations must earnestly implement energy-saving and emission-reduction work, and use green actions to help complete the national carbon neutral strategic goals.
Energy saving and emission reduction is a core issue in the industrial field
The development of industrial technology has led mankind to a more civilized and progressive world. Today's world puts the construction of ecological civilization and sustainable development in a more important position. Energy saving and emission reduction is a core issue in the industrial field, among which the potential for energy saving of the motor system is huge. Electric motors account for about 75% of industrial electricity consumption. Improving the energy efficiency of industrial motors is of great significance to energy conservation and emission reduction. After the implementation of the new motor energy efficiency standard "GB18613-2020 Motor Energy Efficiency Limits and Energy Efficiency Ratings" promulgated by the state, high-efficiency motors will surely become the mainstream and focus of industry technology and the market.
How to improve the energy efficiency of motors? By reducing loss, improving structure, reducing size, optimizing design, improving performance, and increasing stability, the motor can achieve higher energy efficiency, thereby reducing carbon emissions. With the development of electronic technology, new integrated brushless DC motor technology has been widely used. Using advanced microelectronics and control technology, brushless DC motors have gradually replaced traditional ordinary motors and become a new generation of high-efficiency motors.
Maximize motor energy efficiency
The application of advanced microelectronics technology and control technology has changed people’s stereotypes of motors in the past, giving motors a broader space for creativity, keeping pace with the ever-changing world, and promoting the creation of a better human life.
In the field of motor drive control, there are many excellent organizations working hard in the world. As one of them, Fengjiao Technology has persisted in in-depth research in the vertical field of motors for 11 years, and has achieved multiple technical results and obtained hundreds of domestic and foreign technologies. Patent, becoming the leading local IC company in this market segment. The devotion of love will be transformed into energy, driving the world toward the direction that humans expect
In the product ecology of Fengjiao, whether it is IC design, core algorithm, or motor design, the underlying logic is to maximize the energy efficiency of the motor under the premise of high reliability. This advantage is ubiquitous in the product:
Motor drive control chips and intelligent core algorithms are the key to the optimization of motor energy efficiency. In the dozens of application market segments of Fengjia Technology, we provide system-level solutions to help customers continuously optimize products, reduce noise, reduce losses, and reduce power consumption. , Reduce size, save BOM, and improve overall system performance.
With the improvement of people's quality of life, smart water pumps have become more and more widely used, and there are abundant demand markets for dishwasher pumps, drain pumps, cold and heat circulating pumps, and condensate pumps. Take the dishwasher, which is indispensable for smart kitchens, as an example. The high-pressure water pump is the key operating equipment of the whole machine. The single-phase/three-phase non-inductive FOC control scheme provided by Fengjiao and the ASIC/MCU main control chip meet the needs of personalized and precise control. , The hardware integration of the non-inductive FOC algorithm greatly improves product reliability, reduces noise, and makes the motor smaller and more flexible. PWM speed regulation, water shortage detection, and multi-dimensional real-time monitoring and protection can significantly reduce losses. The efficiency of the motor controller is achieved to about 97%, and the system efficiency is increased by 28%
In the typical application of car air conditioner, Fengjia adopts single resistance non-inductive FOC control technology, MCU FU6812 +FD2203+N MOSFETD chip solution, suitable for 12-80V voltage range, power up to 1600W, speed 700-7200RPM, with torque Compensation function, effectively reducing noise and vibration, realizing fast cooling and ultra-quiet at the same time, the efficiency of the motor system is increased by 12%
Work towards carbon neutrality goals
Fengjiao Technology provides customers with a complete set of motor control solutions. On the one hand, it helps customers realize motor design and motor improvement, and improve the energy efficiency of the motor; at the same time, through the latest control algorithm of motor drive, the efficiency of the control scheme is optimized, the noise is reduced, and the vibration is reduced. According to the project case feedback statistics, the Fengjia chip solution can greatly reduce the motor loss, and the motor controller efficiency can reach about 95-99%, thereby increasing the overall system efficiency of the solution by about 5-30%;
Science and technology civilization and ecological civilization develop together and promote each other. Both in the industrial field and the life field, they will continue to put forward higher requirements with this goal. Motor drive is a key implementation link in industrial equipment. Fengjiao’s system motor control solution optimizes and replaces more motor energy efficiency for customers from a market perspective, thereby empowering product competition. From the perspective of ecological civilization, it saves more energy. More electricity and reduce the pressure on the environment, and provide sustainable development of green industrial energy. In the future, Fengjiao will always use this as the direction of technical research and make unremitting efforts to achieve the common goal of carbon neutrality and humanity at an early date.
