At the same time, Fengyu Technology continuously improves its solution capabilities, better serves enterprises, and enhances customer viscosity.
R&D investment has increased significantly year by year, enhancing the team's system-level service capabilities
Fengjia Technology has long been engaged in the research and development, design and sales of BLDC motor drive control special chips, extending to the application side based on chip design and developing into a system-level service provider. Products are widely used in home appliances, power tools, computers and communication equipment, sports travel, industry and automotive and other fields.
In order to meet the product application needs of different downstream fields in a timely manner and ensure the highly practical, cutting-edge technology, international level and cost-effective differentiated competitive advantage of motor drive control chips, Fengyu Technology has continued to increase R&D investment since its inception, and R&D expenses have been increasing.

Through long-term and growing R&D investment, Fengyu Technology now has three core technologies, including chip design, motor drive architecture algorithm and motor technology, and the three cooperate with each other and work together to provide end customers with system-level integrated solutions.
At present, the technical team of Fengyu Technology can put forward the needs of end customers in terms of voltage, speed regulation, control mode, efficiency, noise and other aspects, collect and refine the requirements, analyze the technical difficulties, and realize the application needs of end customers from the three levels of motor design, control algorithm architecture and chip design by the three major technical teams.
Based on the accumulation of technology in these three aspects for many years and the technical team to provide the final system-level service capabilities, Fengyu Technology provides mature overall solutions while providing customers with chip products, helping customers solve the problems of system application in a timely manner, and continuously enhancing the viscosity of the company and customers.
Self-developed hardware dedicated chip platform, take the "specialized and new" route
At present, in the field of motor drive control chips, there are mainly two technical routes in the industry: dedicated chip design and general MCU design, and the core architecture and algorithm implementation path used in different chip design technology routes are fundamentally different.
From the perspective of the implementation path of the internal chip algorithm, the special chip of Fengyu Technology realizes the motor control requirements based on hardware. Fengyue Technology splits the motor control algorithm into position estimator, PI adjustment, SVPWM, Clark transformation, Park transformation and other specific steps, and uses hardware logic gate circuits to design each operating step into an algorithm hardware module, which is combined to achieve motor control. The general MCU chips of most companies in the same industry are mainly based on running software programs to achieve motor control requirements.
From the perspective of external chip core architecture, the special chip of Fengyu Technology implements a similar "specialized and special new" route, focusing on the field of BLDC motor control chips, and finally forming a chip core (ME core) and technical system with complete independent intellectual property rights. In the design of the dedicated ME core for motor control, Fengxia Technology will select the most suitable number of data bits according to the requirements of the BLDC motor control scenario, and has more flexible solutions in the chip design process, which can achieve the optimal balance of BLDC motor drive control efficiency, cost, performance and many other dimensions. From the perspective of actual operation effect, in the field of motor drive control, the main performance indicators of the MCU of the motor main control chip of Fengyu Technology have reached or even exceeded the 32-bit general MCU standard.
The general MCU chip design (suitable for BLDC motor control) is relatively simple, and enterprises in the industry only need to carry out similar secondary development on the basis of mature core architecture and software control program to meet the BLDC motor control requirements. When relevant manufacturers adopt third-party IP cores, the data bits of the IP cores have been determined, such as ARM's Cortex-M series cores are 32 bits. Chip design companies can only write software control programs based on the core of the chip with a given number of data bits.
Fengjia Technology takes the technical path of algorithm hardware, and the various operation steps of the motor control algorithm are realized in the form of hardware logic gate circuits, which requires higher requirements than the software algorithm implementation path, the maturity of its own algorithm, the understanding of motor drive control, and the understanding of specific application scenario requirements.
The rising star of BLDC drive control chips has launched differentiated competition with overseas giants
From the perspective of market development, domestic integrated circuit design enterprises started late, and there is a large gap with international giants such as Texas Instruments (TI) and STMicroelectronics (ST) in terms of company scale and market position.
However, Fengyu Technology has entered the market from the subdivision category of motor drive control, focusing on the research and development of high-performance motor drive control special chips from the beginning of its establishment, starting from the independent research and development of the core architecture of the motor control special processor, and gradually building a chip product architecture with independent intellectual property rights. Compared with the special chips for motors of internationally renowned manufacturers, Fengyue Technology chip products have achieved equal or even better results in technical parameters, control performance and other aspects, and have been recognized by terminal manufacturers.
The industry knows that the technological advancement of products is a comprehensive embodiment of the design capabilities and technical strength of chip design enterprises. Fengtuo Technology motor drive control chip products have their own motor control special core architecture, through continuous R & D investment and technology accumulation, successfully realized the algorithm hardware and device integration, in the field of motor control to achieve higher computing power and better control performance.
It is understood that the special core for motor control developed by Fengyu Technology uses hardware to implement the motor control FOC algorithm, and a FOC operation can be completed at 6 to 7us, and the electrical cycle speed of the non-inductive FOC control scheme can be as high as 270,000RPM. Chip products using ARM authorized core, the control algorithm needs to be implemented through complex software programming, the operation speed mainly depends on the MCU working frequency, and the computing power of the general core under the same main frequency is lower than the dedicated internal accounting power of the algorithm hardware.
The key indicators of the important products of Fengtuo Technology and the comparable products of leading companies in the same industry at home and abroad are compared as follows:
Through comparison, it can be seen that Fengyu Technology adopts the self-developed ME core to undertake complex motor control tasks, and the general MCU core is used to handle auxiliary tasks such as communication to better undertake auxiliary tasks such as external interaction in the "dual-core" architecture, and realizes the motor control algorithm through the hardware technology path to effectively improve the operation speed of the control algorithm and the reliability of the control chip, which is better than the comprehensive performance of the products made by the manufacturers of the general MCU chip.
The successful listing of Fengyue Technology is not only an affirmation of past efforts, but also a new plan for future development. Fengyue Technology pointed out that focusing on the future, the company will focus on the strategic goal of "becoming the world's leading supplier of motor drive control chips and control systems", start from technical research, market expansion, talent training, etc., promote a series of strategic measures, including continuously overcoming technical problems in subdivision fields, independently cultivating a number of technical backbones with sophisticated technology and strong innovation ability, and actively promoting international market development and emerging application market development while consolidating the existing application market, taking independent innovation as the engine , to promote the realization of corporate strategic objectives.
