# Industrial Specification: Rotor/Stator Assembly

## 1. Technical Definition
A critical electromechanical assembly within an X-ray tube that enables high-speed rotation of the anode target.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3000-10000 RPM at 0.1-1.0 N·m torque**. Failure boundary: **Exceeding 12000 RPM or 1.5 N·m torque causes bearing seizure**, Mechanism: **Centrifugal force exceeding bearing yield strength (σ_y = 450 MPa) and thermal expansion mismatch between ceramic bearings (α = 5.5×10^-6 K^-1) and steel shaft (α = 12×10^-6 K^-1)**.

### 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.

- **Caution**: 

### Q: What is the primary function of a rotor/stator assembly in an X-ray tube?
**A**: The rotor/stator assembly enables high-speed rotation of the anode target within the X-ray tube, which is essential for dissipating heat and maintaining consistent X-ray output during medical imaging or industrial inspection procedures.

### Q: Why are materials like molybdenum and tungsten used in these assemblies?
**A**: Molybdenum and tungsten are selected for their exceptional thermal conductivity and high melting points, allowing the assembly to withstand extreme temperatures generated during X-ray operation while maintaining structural integrity and rotational precision.

### Q: How does the rotor/stator assembly impact X-ray tube performance and lifespan?
**A**: A precisely engineered rotor/stator assembly ensures smooth, vibration-free rotation at speeds up to 10,000 RPM, reducing wear on bearings and anode surfaces while preventing thermal damage—directly extending tube lifespan and maintaining consistent imaging quality.
