Extrusion Coating Machine Case — INCT Torque Motor for High-Precision Coating


Background

In lithium battery manufacturing, the coating process plays a critical role in ensuring electrode uniformity and production yield. With increasing demands for higher energy density and consistency, coating machines must achieve both high speed and precise coating accuracy with stable tension control.

Challenges

Conventional drive solutions often face issues such as speed fluctuation, unstable tension during double-sided coating, and complex maintenance. These problems lead to uneven coating thickness and reduced yield.

INCT Torque Motor Solution

The INCT direct-drive torque motor, combined with high-resolution sensors, provides a robust and precise coating solution:

Stable Speed: Speed fluctuation <0.3% at 80rpm, ensuring uniform slurry distribution.

High Accuracy: 25-bit absolute encoder for real-time position feedback, coating thickness accuracy within ±1%.

Reliable Tension: Maintains 30–500N tension range, ideal for frequent double-sided coating.

Simplified System: Direct-drive design eliminates gearboxes, reducing complexity and enhancing long-term reliability.

Value Delivered

With INCT torque motor integration, extrusion coating machines for power and energy storage batteries achieve:

✅ Improved coating consistency

✅ Higher yield rate

✅ Reduced material waste

✅ Lower operational costs
