Magnetic Disc Couplings

Product catalog summary

Introduction
This document provides technical details on Magnetic Disc Couplings, focusing on contactless torque transmission through various claddings. It highlights the design, applications, and technical specifications of these couplings.

Specifications
Magnetic Disc Couplings consist of two opposing discs equipped with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. The design allows for angular misalignment up to 3° and parallel misalignment up to 6 mm while still transmitting nearly full rotational torque. The standard working temperature range is from -40 to +140°C, with special executions up to +280°C.

Applications
The contactless transmission of torque is suitable for various applications, including:

Power transmission for pumps, agitators, and compressors in closed liquid containers.
Power transmission for ventilators in closed containers with gases or steam.
Power transmission for underwater robot arms.
Transmission of display operations on round scales in different media.
Avoidance of motor vibration transfers.
Uncoupling of load influences during weighing processes.

Technical Data
All Magnetic Disc Couplings are made of stainless steel (Material: 1.4005 / 1.4305, with 1.4401 available on request). The document includes a table of torque processes and dimensions, indicating the maximum speed and weight per hub for different types (MTD-0.2 to MTD-50). Types MTD-0.2 to MTD-12 are in stock, while MTD-20 to MTD-50 are manufactured on request.

Conclusion
Magnetic Disc Couplings offer a versatile and efficient solution for contactless torque transmission in various industrial applications. Their ability to accommodate misalignments and operate under a wide range of temperatures makes them suitable for diverse environments.
