# Industrial Specification: Fan Motor

## 1. Technical Definition
An electric motor that converts electrical energy into mechanical rotation to drive fan blades for air movement.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kW, 1000-3000 RPM, 85-240 VAC, 50-60 Hz**. Failure boundary: **Winding temperature exceeds 155°C (Class F insulation limit), bearing vibration exceeds 4.5 mm/s RMS, shaft imbalance exceeds 0.4 g·mm/kg**, Mechanism: **Insulation breakdown due to thermal aging (Arrhenius equation: degradation rate doubles per 10°C rise above 155°C), bearing fatigue from Hertzian contact stress exceeding 1.8 GPa**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.

- **Caution**: 

### Q: What are the main advantages of copper windings in fan motors?
**A**: Copper windings provide superior electrical conductivity, reduce energy loss through heat, and enhance motor efficiency and longevity compared to aluminum alternatives.

### Q: How do I choose between ball bearings and sleeve bearings for my fan motor?
**A**: Ball bearings offer higher load capacity and longer life for continuous industrial use, while sleeve bearings are quieter and more cost-effective for lighter-duty applications.

### Q: What maintenance is required for industrial fan motors?
**A**: Regular maintenance includes cleaning to prevent dust buildup, checking bearing lubrication, monitoring vibration levels, and ensuring proper electrical connections to prevent overheating.
