# Industrial Specification: Electric Motor Stator Lamination Stack

## 1. Technical Definition
Precisely stacked and bonded electrical steel laminations forming the stationary magnetic core of an electric motor.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Magnetic flux density: 1.5-1.8 T (Tesla), Core loss: 2.5-4.0 W/kg at 50 Hz, 1.5 T, Stacking factor: 0.95-0.98**. Failure boundary: **Magnetic saturation at 2.1 T (silicon steel), Interlamination insulation breakdown at 500 V/mm, Stack bond failure at 15 MPa shear stress**, Mechanism: **Hysteresis and eddy current losses exceeding material Curie temperature (740°C for Fe-3%Si), leading to insulation degradation and magnetic property loss**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| High-frequency harmonic currents from PWM inverter (switching frequencies &gt;5 kHz) | 8 | Excessive eddy current heating in laminations (&gt;120°C), causing insulation degradation and interlamination shorting | Implement grain-oriented electrical steel with &lt;0.27 mm thickness and phosphate insulation coating |
| Mechanical vibration at motor natural frequency (typically 100-500 Hz) | 8 | Progressive stack delamination and increased magnetic reluctance, reducing motor efficiency by &gt;15% | Apply epoxy bonding with 10-15 MPa shear strength and implement vibration damping mounts |

## 5. Engineering Risks & FAQ

- **Caution**: 

### Q: What are the benefits of using non-oriented electrical steel for stator laminations?
**A**: Non-oriented electrical steel (SiFe) provides uniform magnetic properties in all directions, reducing core losses and improving motor efficiency. Combined with C-5 or C-6 insulation coatings, it minimizes eddy current losses in the stator core.

### Q: How does stacking factor affect electric motor performance?
**A**: Stacking factor measures how densely laminations are packed. A higher stacking factor (typically 95-98%) increases magnetic flux density, improving torque and efficiency while reducing core losses and thermal buildup in the motor.

### Q: What specifications should I consider when ordering stator lamination stacks?
**A**: Key specifications include core loss at 1.5T/50Hz (W/kg), lamination thickness (typically 0.35-0.65mm), slot count, stack length, stacking factor (%), and stacking pressure (MPa). These determine motor efficiency, power density, and thermal performance.
