# Industrial Specification: Rotor/Stator (Motor)

## 1. Technical Definition
The rotating (rotor) and stationary (stator) electromagnetic components that form the core of an electric motor.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-15000 RPM (rotational speed), -40Â°C to 180Â°C (temperature), 0.1-10 mm (air gap clearance)**. Failure boundary: **Rotor imbalance exceeding 0.4 gÂ·mm/kg, stator winding insulation breakdown at 1.5 kV/mm, bearing temperature exceeding 120Â°C**, Mechanism: **Electromagnetic hysteresis losses (iron losses) following Steinmetz equation P_h = k_h f B^Î±, where k_h=0.04 W/(mÂ³Â·HzÂ·TÂ²), f=frequency, B=flux density, Î±=1.6; centrifugal force exceeding yield strength Ïƒ_y=250 MPa at critical speed Ï‰_c=âˆš(k/m)**.

- **Caution**: 

### Q: What are the key differences between rotor and stator components in electric motors?
**A**: The rotor is the rotating part that converts electromagnetic energy into mechanical motion, while the stator is the stationary part that creates the magnetic field. Together they form the core electromagnetic system of any electric motor.

### Q: Why is electrical steel used for rotor and stator laminations?
**A**: Electrical steel (silicon steel) is used because it has high magnetic permeability and low core loss, which reduces energy waste as heat and improves motor efficiency. The laminated structure minimizes eddy current losses.

### Q: How do permanent magnet rotors differ from squirrel cage rotors?
**A**: Permanent magnet rotors use embedded magnets (like neodymium) to create a constant magnetic field, offering higher efficiency and power density. Squirrel cage rotors use aluminum or copper bars in a cage configuration, induced by the stator's magnetic field, making them more durable and cost-effective for many industrial applications.

## 6. Manufacturing Compliance
