# Industrial Specification: Separator Feeding &amp; Tensioning Unit

## 1. Technical Definition
A precision component within battery manufacturing equipment that precisely feeds and maintains tension on separator material during electrode stacking.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 N·m torque at 10-100 mm/s feed rate with 0.1-2.0 N tension force**. Failure boundary: **Tension force exceeds 2.5 N causing separator elongation beyond 0.5% plastic deformation threshold**, Mechanism: **Hooke's Law elastic limit violation: σ = Eε where E = 1.2 GPa for polyolefin separator material, exceeding yield strength of 6 MPa**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
