# Industrial Specification: Power Unit

## 1. Technical Definition
The power generation and transmission system that provides mechanical energy to drive the soil compactor's operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 bar hydraulic pressure, 1800-2200 RPM rotational speed**. Failure boundary: **Hydraulic pressure exceeding 42 bar causes seal rupture; rotational speed below 1500 RPM induces insufficient torque for compaction**, Mechanism: **Hydraulic fluid cavitation at pressures below 15 bar; bearing thermal fatigue from continuous operation above 2200 RPM exceeding 120°C**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
