# Industrial Specification: Motor Drive Interface

## 1. Technical Definition
Electronic interface component that connects control systems to motors in anti-sway systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC, 0-10 V analog control signal, -20°C to +85°C ambient temperature**. Failure boundary: **Input voltage exceeding 60 VDC causes MOSFET gate oxide breakdown at 6 MV/cm dielectric strength, control signal exceeding 12 V saturates op-amp inputs, junction temperature exceeding 150°C triggers thermal shutdown**, Mechanism: **Electromigration in copper traces at current densities &gt; 10^6 A/cm², dielectric breakdown in MOSFET gate oxide at electric fields &gt; 6 MV/cm, thermal cycling fatigue in solder joints due to coefficient of thermal expansion mismatch between FR4 (14 ppm/°C) and lead-free solder (21 ppm/°C)**.

### 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.
