# Industrial Specification: Positioning System

## 1. Technical Definition
A precision control system that determines and maintains the exact position of items on a rotating carousel.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 μm positioning accuracy at 0.5-30 RPM carousel rotation**. Failure boundary: **Positional error exceeding 150 μm or servo lag exceeding 15 ms at 30 RPM**, Mechanism: **Servo motor cogging torque exceeding 0.15 N·m combined with encoder quantization error of 12-bit resolution**.

### 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.
