Magnetic Particle Clutch Technical Summary

1. Product Overview

This document provides detailed specifications and installation guidelines for a series of magnetic particle clutches (models ZKC040AA, ZKC020AA, ZKC010AA, ZKC005AA, ZKC2S5AA, ZKC1S2AA) operating at DC 24V and 75ºC. These clutches are designed for precise torque transmission with controlled slippage and forced-air cooling capabilities.

2. Specifications

• Rated Torque: Ranges from approximately 1.2 Nm to 550 Nm depending on model.
• Moment of Inertia (J): Values vary per model, e.g., from 1.2x10^-4 kgm² to 12.2x10^-4 kgm².
• Maximum Speed: Up to 2800 rpm for higher torque models, lower for smaller units.
• Weight: From about 0.1 kg to 2.0 kg depending on clutch size.
• Power and Current: Power consumption ranges from 0.1 W to 2.4 W; current ranges from 0.05 A to 2.4 A.
• Allowable Slippage Power: Specified for forced-air cooling conditions, ensuring clutch durability under continuous slip.
• Air Pressure and Volume: Required for forced-air cooling, with air pressure around 30-84 Pa and air volume from 1.2 to 3.5 m³/min depending on model.
• Dimensions: Detailed shaft and clutch dimensions provided, including shaft diameters (d), lengths (L1-L4), and mounting hole specifications (e.g., M10*1.5P*15L).

3. Installation Guidelines

1. Insert the clutch assembly securely into the installation board to ensure stable mounting.
2. Use a spring-type flexible coupling to connect the clutch shaft to the load shaft. Maintain concentricity and angular alignment within the allowable tolerance of the coupling.
3. When installing belt pulleys or similar components, ensure the shaft load remains within the permitted range.
4. Install mounting plates on both ends of the shaft to provide proper support.

4. Performance Characteristics

Graphs and data illustrate the relationship between energizing current and torque output for each model, showing torque increases with current up to rated values. Allowable continuous slip rates and torque levels under natural cooling conditions are provided, indicating operational limits to prevent overheating and wear.

5. Key Parameters and Limitations

• Torque Establishment Time: Time constants for torque build-up range from 0.1 to 2.0 seconds depending on model.
• Maximum Operating Speed: Specified per model to avoid mechanical damage.
• Allowable Continuous Slip: Defined for natural and forced-air cooling to ensure clutch longevity.
• Weight of Magnetic Powder: Varies by model, affecting clutch inertia and response.

6. Additional Notes

The document includes detailed shaft dimension tables with tolerances (h7, g7), mounting hole patterns, and air injection port locations. These ensure compatibility with mechanical systems and proper cooling airflow.

Special attention is required to maintain alignment and load limits during installation to optimize clutch performance and lifespan.
