# Industrial Specification: Positioning Motors

## 1. Technical Definition
Electric motors that precisely control the movement and positioning of components within a treatment table system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 N·m continuous torque, 0.01-0.1 mm positioning accuracy, 100-3000 RPM speed range**. Failure boundary: **Insulation breakdown at 155°C (Class F insulation), bearing failure at 10⁷ stress cycles (L10 life), demagnetization at 80°C for NdFeB magnets**, Mechanism: **Thermal degradation of insulation materials (Arrhenius rate law), fatigue failure in bearing raceways (Palmgren-Miner rule), Curie temperature-induced magnetic flux loss**.

### 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.
