# Industrial Specification: Drive Unit

## 1. Technical Definition
A mechanical assembly that provides the motive power to move a conveyor belt or chain within a conveyor section.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 m/s belt speed, 0.75-15 kW power output, 0.8-1.2 m/s² acceleration**. Failure boundary: **Bearing temperature exceeding 120°C, gear tooth bending stress surpassing 250 MPa, motor winding insulation breakdown at 180°C**, Mechanism: **Bearing failure due to Hertzian contact stress exceeding material yield strength (σ_y = 450 MPa for AISI 52100 steel), gear tooth pitting from subsurface shear stress exceeding 0.3×HB (Hardness Brinell), insulation breakdown from partial discharge at electric field strength &gt;3 kV/mm**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
