# Industrial Specification: Movement Assembly

## 1. Technical Definition
A mechanical assembly responsible for controlled motion within a display mechanism.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 NÂ·m torque, 0.05-2.0 mm/s linear velocity, Â±0.01 mm positioning accuracy**. Failure boundary: **Exceeds 6.0 NÂ·m static torque, exceeds 2.5 mm/s velocity for &gt;30 seconds, exceeds Â±0.02 mm positioning error**, Mechanism: **Bearing fatigue at 10â¶ cycles (Miner's rule), lead screw deformation at 250 MPa stress (exceeding yield strength of 17-4PH stainless steel), stepper motor demagnetization at 120Â°C (Curie temperature of NdFeB magnets)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
