Driven by the dual forces of the global energy structure transformation and the Industrial 4.0 wave, the new energy equipment industry is shifting from "scale expansion" to "efficiency competition" and "precision revolution". The absolute value magnetic scale encoder, with its core advantages such as power-off memory, anti-pollution, long stroke, and high reliability, is upgrading from the "perception end" of the automation system to the "decision node" in the era of intelligent manufacturing.

This white paper is based on the latest data of the global magnetic encoder market, deeply analyzing the technical penetration path of absolute value magnetic grating encoders in the new energy sectors such as lithium batteries, photovoltaics, wind power, and new energy vehicles. It also combines the technical parameters and industry application cases of products like FMG3000 under the brands of Tianxian Digital Intelligence and Magnetic Positive Intelligence, systematically elaborating on the industrial opportunities and competitive landscape of magnetic sensing technology in the new energy era in China.

Chapter 1: Industry Background: The "Precision" Turning Point of New Energy Equipment

1.1 Structural Upgrading of the New Energy Industry

The global new energy industry is undergoing a paradigm shift from "scale expansion" to "efficiency competition". The requirements for the coating accuracy of electrode sheets in lithium battery manufacturing have advanced from micrometer level to sub-micrometer level, the main shaft synchronization accuracy of photovoltaic silicon wafer slicing directly determines the yield rate, the angle feedback error tolerance of wind turbine pitch systems has been compressed to the angular level, and the assembly accuracy of the three-electric system of new energy vehicles directly affects the performance and safety of the entire vehicle.

Against this backdrop, automation equipment has put forward requirements for the precision, stability, and environmental adaptability of position and speed measurement far beyond those of traditional industries. Encoders - as the "sensory system" of motion control systems - their performance boundaries directly determine the upper limit of equipment precision and the lower limit of reliability.

1.2 Comparison of Encoder Technology Routes: Magnetic vs. Optical

Currently, the high-precision displacement measurement field mainly has two technical routes:

Optical encoders: The upper limit of precision is higher (up to nanometer level), but they have a natural drawback - they are extremely sensitive to dust, oil stains, water vapor, and vibration, have poor environmental adaptability, and have strict installation accuracy requirements. In the harsh working conditions of new energy production lines (such as electrolyte evaporation in the lithium battery workshop, cutting debris liquid and dust in the photovoltaic slicing workshop, and lubricant contamination in the wind turbine gearbox), the reliability of optical encoders faces severe challenges.

Magnetic encoders: Based on the magnetoresistance effect (AMR/GMR/TMR) or Hall effect for non-contact measurement, they naturally have environmental advantages such as anti-pollution, anti-vibration, anti-humidity, and wide temperature range. In recent years, with breakthroughs in magnetic material processing and signal processing algorithms, the resolution and precision of magnetic encoders have continuously improved, gradually penetrating from "environmental adaptability priority" scenarios to high-precision fields.

Industry research institutions' data confirm this trend: The market is undergoing a 42% technological migration from optics to magnetism, and the penetration rate of magnetic encoders in high-reliability scenarios is continuously increasing.

1.3 Strategic Value of Absolute Value Encoders

In the classification of encoders, absolute value encoders have essential advantages over incremental encoders: They can retain the absolute position after power failure and do not require re-zeroing after power-on. This characteristic is of great significance for new energy equipment - the lithium battery production line operates 7×24 hours continuously, any re-calibration after shutdown will cause production losses; the wind turbine pitch system's rapid recovery ability after grid fluctuations directly relates to safety.

According to a report by strategic management consulting firm Lucintel, the market is undergoing a 42% technological migration from optics to magnetism, and the penetration rate of absolute value magnetic encoders in high-reliability scenarios is continuously increasing. According to Global Info Research data, the global revenue of magnetic absolute encoders is approximately 630 million US dollars in 2024, and is expected to reach 1.034 billion US dollars in 2031, with a compound annual growth rate (CAGR) of 7.4%.

Chapter 2: In-depth Technical Analysis: The Core Competitiveness of FMG3000

This multi-protocol compatibility design significantly reduces the system integration threshold and enables rapid adaptation to different brands of controllers and drivers.

2.2 Five core technological innovations

1. FPGA hardware acceleration algorithm

The signal processing of traditional encoders relies on MCU software operations, which have processing delays and jitter. The FMG3000 adopts a FPGA hardware parallel processing architecture, implementing core algorithms such as signal decoding, filtering, and interpolation at the hardware level. The position delay is controlled within 62.5μs, meeting the strict requirements for real-time performance in high-speed motion control scenarios.

2. Autonomous wafer fabrication of core components

In the context of increasingly important supply chain security, the core sensing chip of the FMG3000 is designed and fabricated independently, ensuring performance consistency and supply stability from the source. This is a strategic value point that cannot be ignored for new energy equipment enterprises that pursue autonomous control of the supply chain.

3. Segmented temperature compensation technology

The temperature coefficient of magnetic materials is a key factor affecting the accuracy of magnetic encoders. The FMG3000 incorporates multiple-point temperature sensors and combines segmented compensation algorithms to automatically correct accuracy within the working temperature range of -10℃ to +70℃, effectively suppressing temperature drift errors. This feature is particularly important in wind power and outdoor energy storage scenarios with significant temperature variations.

4. Automatic gain and bias control

The magnetic signal strength fluctuates with installation gap, temperature, and magnetic field environment. The FMG3000's automatic gain control (AGC) and automatic bias control (AOC) functions can adjust signal processing parameters in real time to ensure the output signal always remains within the optimal signal-to-noise ratio range, reducing reliance on installation accuracy and enhancing the robustness of the system.

5. AI deep training and non-intrusive optimization

The FMG3000 is one of the industry's first magnetic scale encoder products to introduce AI algorithms. Through the built-in AI model to conduct deep training on the equipment's historical operation data, the encoder can achieve dynamic verification and non-intrusive optimization - automatically compensating for errors during operation and becoming more accurate over time. Tianxian Digital Intelligence confirmed in its technical announcement that this feature is the core differentiating highlight of its absolute value magnetic scale encoder.

Chapter 3: In-depth Application Analysis in the New Energy Field

3.1 Lithium Battery Manufacturing: Precision Guarantee Throughout the Entire Process from Coating to Formation

The most demanding displacement control accuracy requirements in lithium battery production are concentrated in the coating, winding, and formation capacity measurement stages.

In the electrode coating machine, absolute value magnetic scale encoders are used for closed-loop control of the movement position of the coating mold, ensuring consistent coating thickness. The FMG3000's 0.1μm resolution can precisely control the gap between the mold and the electrode, combined with AI optimization algorithms, automatically compensating for the accuracy offset caused by mechanical wear during long-term operation.

In the winding machine, the encoder provides real-time feedback on the relative position of the separator and the electrode, and the FPGA hardware acceleration algorithm compresses the signal delay to the microsecond level, ensuring multi-axis synchronization accuracy. The absolute value characteristic avoids parameter loss due to unexpected power outages, significantly reducing production risks. In capacitor charging equipment, absolute value positioning under multi-axis linkage does not require zeroing each time, significantly improving the production cycle. The segmented temperature compensation function of FMG3000 ensures stable accuracy in the high-temperature environment of the charging cabinet.

3.2 Photovoltaic Manufacturing: High-Frequency Response of Slicing and Stringing

The spindle and feed axis of the photovoltaic silicon wafer slicing machine require extremely high precision synchronization control. Unlike traditional optical encoders, magnetic grating encoders are not affected by chip fluid, silicon powder dust, etc., and even if the sensor surface is covered with a thin layer of contaminants, they can still maintain stable signal output.

In the stringing machine, the high-speed reciprocating motion of the welding head poses a challenge to the encoder's dynamic response. The maximum speed of 5m/s and the position delay of 62.5μs of FMG3000 can support high-speed positioning above 40 times/second, and combined with AI deep training for adaptive optimization of the motion trajectory, it can effectively reduce the fragmentation rate.

3.3 Wind Power and Energy Storage: Benchmark of Reliability in Harsh Environments

The pitch and yaw systems of wind power units have long faced extreme conditions such as vibration, temperature differences, oil contamination, and humidity. The IP67 protection level, 300m/s² anti-vibration capability, and -10℃ to 70℃ wide temperature range design of FMG3000 can fully adapt to the harsh environment inside the nacelle.

The core value of absolute value encoders is particularly prominent in the wind power scenario: After equipment power outage due to grid fluctuations or regular maintenance, the system can continue to operate from the broken point without re-zeroing, which directly relates to the safety and utilization rate of the wind turbine.

In the energy storage container, the long-stroke transportation of the heavy-duty truss robot poses requirements for the encoder's measurement length. FMG3000 supports a maximum measurement length of 16.3 meters and a repeatability accuracy of<2μm, suitable for the automated storage requirements of large-scale energy storage systems.

3.4 New Energy Vehicle Manufacturing: Precise Collaboration in Welding, Assembly, and Inspection

In new energy vehicle factories, welding robots, assembly lifts, and three-electric system inspection tables use magnetic grating encoders for position closed-loop control. The multi-robot collaboration advantage of absolute value encoders lies in: there is no need to "find the origin" after each startup, and it can directly continue to operate from the broken point, reducing cycle loss.

According to industry research, the usage of encoders in the new energy vehicle field has increased by at least 500 yuan per vehicle compared to traditional fuel vehicles, mainly applied to inverter systems, motor cooling systems, and starting generator systems. Among them, magnetic encoders, due to their strong environmental adaptability, small size, and controllable cost, have become the mainstream choice for sensor solutions in new energy vehicles.

According to Global Growth Insights data, the usage of encoders in the new energy vehicle field has increased by 37%, and it is expected to become the fastest-growing application field in the encoder market.
