# Industrial Specification: Electric Motor

## 1. Technical Definition
An electromechanical device that converts electrical energy into mechanical energy to drive the fan blades.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.75-1.15 per unit voltage (e.g., 345-529V for 460V nominal), 0-1.2 per unit torque, 0-3600 RPM for 60Hz 4-pole design**. Failure boundary: **Insulation breakdown at 150°C (Class F insulation), bearing failure at 0.1mm radial play, rotor bar fracture at 10^7 stress cycles at 120MPa**, Mechanism: **Electromagnetic torque production via Lorentz force (F = I × B), with failure primarily from Joule heating (P_loss = I²R) exceeding thermal dissipation capacity**.

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

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$
