# Industrial Specification: Generator Rotor

## 1. Technical Definition
The rotating component within a generator that converts mechanical energy into electrical energy through electromagnetic induction.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3000-3600 RPM at 50-60 Hz synchronous frequency, 80-120°C winding temperature, 0.5-1.5 mm air gap clearance**. Failure boundary: **Exceeds 4000 RPM centrifugal force limit (σ_max &gt; 250 MPa yield strength), winding temperature &gt; 155°C (Class F insulation limit), air gap eccentricity &gt; 0.3 mm causing magnetic pull imbalance**, Mechanism: **Centrifugal stress exceeding rotor forging yield strength (σ = ρω²r²), insulation thermal degradation following Arrhenius equation (k = A·e^(-Ea/RT)), unbalanced magnetic pull (UMP = (B²·A)/(2μ₀) with eccentricity)**.

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

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

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in generator rotor construction?
**A**: Generator rotors typically use electrical steel laminations for the core, copper windings for conductivity, insulation materials for safety, and structural steel for durability and support.

### Q: What are the main components in a generator rotor BOM?
**A**: Key BOM items include field windings (for magnetic field generation), retaining rings (to secure windings), rotor core (made of laminated steel), and rotor shaft (providing structural support and rotation).

### Q: How does a generator rotor convert mechanical energy to electrical energy?
**A**: The rotor rotates within a stator, creating a changing magnetic field through its windings. This induces electrical current in the stator windings via electromagnetic induction, converting mechanical rotation into electrical power.

## 6. Manufacturing Compliance
