In the field of automated motion control, the selection of encoders has long been trapped in an either-or dilemma. The absolute value encoder has high accuracy, power-off memory function, and is safe and reliable, but its price is always high; the incremental encoder is cost-effective, but it is difficult to meet the strict requirements of high-end applications for the continuity and security of position information. Equipment manufacturers have to constantly balance between performance and cost, either paying a high price for the absolute value solution or compromising on the increased complexity of the incremental solution.

It was in this industry context that Tianxian Digital Intelligence/Magnetic Zheng Intelligent Technology launched the FMG11 absolute value magnetic scale encoder system. The birth of this product was not simply a matter of stacking parameters on an existing technical path; rather, it started from the fundamental logic, attempting to answer a long-standing problem in the industry that had never been perfectly resolved: Can one encoder simultaneously possess the composure of absolute values and the accessibility of incremental values?

Technical core: Not trade-offs, but reconstruction

The reason why FMG11 dared to propose this proposition lies in the revolutionary nature of its technical architecture. Unlike most encoder products on the market that rely on general-purpose chip solutions, the core components of FMG11 are all based on self-developed wafer fabrication. This decision in the supply chain means stability and controllability, while in the technical aspect, it opens up the space for deep optimization - without compromising within the functional boundaries of general-purpose chips, but can tailor the signal path for specific application scenarios of magnetic scale encoders.

Based on this, the R&D team introduced FPGA hardware acceleration algorithms into the field of magnetic scale encoders. The parallel processing capability of FPGA enables signal acquisition, decoding, and verification to be completed at extremely low latency on the hardware level, which is particularly direct for applications with extremely high dynamic response requirements such as linear motor modules and multi-motor variable torque motors. Position feedback is no longer just a "measured result", but becomes a synchronous signal that the control system can trust in real time.

In terms of the stability of accuracy, FMG11 adopts segmented temperature compensation technology. Industrial environments are far from constant temperature laboratories. From northern cold workshops to southern summer semiconductor dust-free production lines, the temperature range can reach tens of degrees Celsius. The precision drift of traditional encoders in the full temperature range is often an imperceptible but real source of error for users. Segmented compensation independently models and calibrates different temperature intervals, controlling the influence of temperature on measurement accuracy to an extremely low level.

In tandem with this is the automatic gain and bias control mechanism. The signal quality of magnetic scale encoders is affected by installation tolerances, aging of magnetic scale strips, and environmental interference, and traditional solutions require manual intervention for debugging, relying on the experience of engineers and increasing the cost of on-site deployment. FMG11 dynamically adjusts the front-end gain and bias parameters in real time based on the monitoring of signal amplitude and bias status, keeping the system in the optimal signal-to-noise ratio state, with more tolerant installation and more stable operation.

Intelligent advancement: When the encoder begins to "learn"

If the above technologies more reflect the solid foundation of hardware and underlying algorithms, then the truly differentiated capabilities of FMG11 for the future lie in the introduction of AI deep training, dynamic verification, and imperceptible optimization functions.

This is not a marketing-level concept packaging, but a complete online adaptive mechanism. During the operation of the equipment, FMG11 continuously collects data such as motion trajectories, speed fluctuations, and position repeatability, and conducts real-time analysis and verification through the embedded lightweight AI model. When the system identifies certain regular error characteristics, it will automatically optimize parameters, and all of this is imperceptible to the end users.

This means that FMG11 is not just a feedback component, but an "improving with use" intelligent node. In scenarios such as linear motor modules, industrial robots, and semiconductor equipment with long-term operation and strict repetitive positioning requirements, this continuous self-optimization ability can significantly delay the degradation of accuracy due to mechanical wear and environmental changes, extending the effective service life of the equipment.

Value anchor point: Another solution for cost reduction and efficiency improvement

The most direct commercial value of FMG11 can be summarized in one sentence: It makes the absolute value encoder no longer a "luxury item" for high-end equipment, but a "standard feature" for automation solutions.

In the past, many equipment manufacturers, when facing mid-range market demands, had to adopt the compromise solution of "incremental encoder + power-off reset". Although this solution saved material costs, it brought about increased system complexity, increased power-on reset time, and lost position after sudden power outages, among other hidden costs. For equipment manufacturers, these hidden costs are often more difficult to quantify and are more likely to be magnified by after-sales issues after project delivery.

FMG11, through autonomous supply chain control and innovative architecture design, has lowered the price of the absolute value encoder to the level of incremental encoders, allowing equipment manufacturers to no longer have to make a "binary choice" between performance and price. Whether it is a linear motor module manufacturer, a screw motor module manufacturer, a system integrator, or an automation equipment manufacturer, they can directly obtain the complete functions of the absolute value encoder - power-off memory, no need for reset, high speed and high precision, stable and reliable - without significantly increasing the BOM cost.

Scenario adaptation: From core components to industry depth

From the application perspective, the coverage of FMG11 almost spans the core areas of modern equipment manufacturing.

In the fields of linear motor modules and screw motor modules, it serves as the core unit of position feedback, directly affecting the positioning accuracy and dynamic response of the modules; in multi-motor variable torque motor scenarios, the collaborative control of multiple motors places extremely high requirements on the real-time performance and anti-interference ability of position feedback. The FPGA hardware acceleration and AI dynamic verification capabilities of FMG11 are particularly prominent in such scenarios.

In high-end manufacturing fields such as new energy, automobiles, industrial robots, and semiconductor equipment, equipment requires higher reliability, accuracy, and long-term stability than general industrial scenarios. The full temperature range compensation, supply chain stability brought by independent wafer fabrication, and long-term accuracy retention ability of FMG11 constitute a complete value chain for these industries.

In addition, in traditional manufacturing fields such as machine tools, stone processing, woodworking machinery, aluminum and window processing, and printing equipment, FMG11 can also help traditional equipment achieve technological upgrades to digital and intelligent control by virtue of its good environmental adaptability, simplified installation and commissioning process, and highly competitive price. 

The self-defined proposition of a magnetic sensor head enterprise

As another outstanding achievement of Tianxian Digital Intelligence and Magzhen Intelligent, the birth of FMG11 was not accidental. The two enterprises have been deeply engaged in the field of magnetic sensors for many years, accumulating rich technical expertise in products such as magnetic grating encoders, eddy current sensors, and magnetic levitation flexible ring-shaped line encoders. More importantly, the enterprise has always regarded "helping Chinese intelligent manufacturing to enter the global stage" as its mission. This determines that its product development path cannot be simply following and imitating, but must achieve independent breakthroughs at the key technologies and core components level.



FMG11 precisely embodies this concept. It is neither a simplification of the absolute value encoder nor an upgrade of the incremental encoder; rather, it represents a redefinition based on an independent technological system. As more and more automation equipment manufacturers start to re-examine the cost structure of encoder selection, what FMG11 represents might be a more rational and more closely aligned with industrial actual needs new option in the field of position feedback.
