In the field of high-end intelligent manufacturing, the magnetic levitation flexible ring-shaped line system is gradually becoming the new standard for precise transmission. However, traditional encoders always face two major technical bottlenecks in the application process: the problem of signal stability caused by the limitation of the induction gap, and the decrease in accuracy caused by the distortion of the magnetic field during turning. These pain points severely restrict the development potential of flexible manufacturing systems.

In-depth Analysis of Industry Pain Points

Induction gap limitation: Traditional solutions require strict installation tolerances (usually < 5mm), making it difficult to maintain stable signal quality in actual operation

Deterioration of turning accuracy: The magnetic field distribution at the annular line turning point is complex, and traditional encoders will experience signal attenuation and amplification of angular errors

Innovative Breakthroughs of HMS Series Magnetic Levitation Absolute Value Magnetic Encoders:

After three years of dedicated research and development, the HMS magnetic levitation absolute value encoder feedback system we have launched has completely solved these industry problems through two core technologies:

Adaptive gap compensation technology

It innovatively extends the working clearance to 8-10mm, allowing for a dynamic deviation of ±3mm. The intelligent gain control system adjusts the signal strength in real time to ensure the measurement stability when the gap changes.

2. Dynamic magnetic field optimization algorithm

The real-time magnetic field compensation implemented by FPGA hardware reduces the Angle error in the turning area to 1/10 of the conventional value

Measured data: Under the condition of sharp turns, the position repeatability accuracy reaches ±0.1um.

Verification of technical advantages

In the magnetic levitation flexible production line upgrade project of a certain 3C manufacturing enterprise in Shenzhen: The installation and commissioning time was shortened by 60% (thanks to the loose gap requirements). The defect rate of products at the turning points decreased from 1.2% to 0.05%. The overall energy consumption of the system is reduced by 15% (thanks to the frictionless design).

Industry application achievements:

Semiconductor: Used in wafer handling manipulators to maintain a position of ±0.003mm at the turning point.

New energy: In battery electrode sheet winding equipment, eliminate tension fluctuations at the turning points.

Medical: Constant precision control throughout the entire process of the circular guide rails for precision inspection equipment.
