INCT GmbH
In lithium battery manufacturing, extrusion coating plays a critical role in determining electrode uniformity and overall production yield. As requirements for higher energy density and process consistency increase, coating machines must operate at high speed while maintaining precise coating accuracy and stable tension control.
This project focuses on an INCT torque motor–based solution for extrusion coating machines, supporting stable speed control, accurate thickness regulation, and reliable tension performance for battery electrode coating.
Unstable rotational speed can cause uneven slurry distribution, leading to thickness variation and reduced yield.
Frequent switching between coating sides places high demands on tension stability across a wide operating range.
Conventional drive solutions with mechanical transmission increase system complexity and long-term maintenance requirements.
To address these challenges, INCT provided a direct-drive torque motor solution for extrusion coating applications.
The solution integrates:
Delivering stable rotational speed with speed fluctuation controlled below 0.3% at 80 rpm, supporting uniform slurry distribution.
A 25-bit absolute encoder provides real-time position feedback, enabling coating thickness accuracy within ±1%.
Supports a wide tension range of 30–500 N, suitable for frequent double-sided coating processes.
Eliminates gearboxes and mechanical transmission elements, simplifying system design and improving long-term reliability.
The implemented INCT torque motor solution achieved the following performance outcomes:
• Stable rotational speed with less than 0.3% fluctuation at 80 rpm
• Coating thickness accuracy maintained within ±1%
• Reliable tension control across 30–500 N operating range
• Reduced system complexity through gearbox-free direct-drive design
Removes mechanical transmission variability and improves speed and tension stability.
Accurate encoder feedback enables precise coating thickness regulation.
The solution is optimized specifically for extrusion coating requirements in lithium battery production.
