# Industrial Specification: Blower Motor

## 1. Technical Definition
Electric motor that drives the blower fan in an aeration unit to generate airflow.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kW at 400V AC, 50-60 Hz, 1400-2800 RPM**. Failure boundary: **Winding temperature exceeds 155°C (Class F insulation limit) for &gt;30 minutes or bearing vibration exceeds 4.5 mm/s RMS**, Mechanism: **Electromagnetic hysteresis losses and eddy currents in stator laminations generate Joule heating; unbalanced magnetic pull induces rotor eccentricity**.

### 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.
