Magnetic Coupling

To provide an accurate quote and solution for magnetic couplings, we need to provide the following key information. This information will help us make a comprehensive evaluation from the aspects of technical feasibility, material selection, cost estimation, etc.:

1. Basic Application Parameters

• Application Scenarios: industrial equipment (pumps, compressors, etc.), vacuum environment, medical equipment, food processing, chemical explosion protection, etc.
• Transmitted Power (kW) or Torque (N·m).
• Speed ​​Range (RPM): Is high-speed or variable-speed operation involved?
• Shaft Diameter Size: The diameter of the drive end and the driven shaft (mm/in).

2. Performance Requirements

• Air Gap Distance: The axial or radial gap between the two magnets (affects the magnetic force transmission efficiency).
• Torque Transmission Capacity: Is overload protection required (magnetic coupling is suitable for slip protection)?
• Efficiency Requirements: The efficiency of conventional magnetic coupling is about 90%~98%. Does it need to be optimized?
• Temperature Range: Working environment temperature (high temperature may demagnetize, and low temperature affects material performance).

3. Environmental Conditions

• Sealing Requirements: Is complete isolation required (such as vacuum, high pressure or corrosive media)?
• Protection Level: IP level (such as IP67 waterproof and dustproof).
• Special Environment: corrosive, explosive (ATEX certified), clean room (dust-free), etc.

4. Structural Type

• Axial magnetic coupling (disc type) or radial magnetic coupling (cylinder type)?
• Is a customized shape required (such as flange connection, special installation space restrictions).
• Is a dynamic design with adjustable air gap required?

5. Material Requirements

• Magnet Type: NdFeB (high performance), SmCo (high temperature resistance), ferrite (low cost)?
• Conductor Material: stainless steel (corrosion resistance), aluminum alloy (lightweight) or other?
• Sealing Material: fluororubber, PTFE, etc. (for chemical compatibility).

6. Other Requirements

• Life Expectancy: continuous operation time or maintenance cycle.
• Certification Standards: CE, UL, FDA (medical/food industry), etc.
• Budget Range: Do you need to balance cost and performance?

Why do we need this information?

• Air gap and torque: The torque capacity of the magnetic coupling drops sharply as the air gap increases, and accurate calculation is required.
• Temperature effect: High temperature may cause magnet demagnetization (e.g., NdFeB should be used with caution when it exceeds 80°C).
• Corrosive environment: Material selection directly affects life (e.g., 316L stainless steel is required for seawater applications).

The more detailed information you provide, the more cost-effective solutions you can match (e.g., small power pumps may use standard products, while high torque compressors need to be customized). Do you have specific parameters or drawings? We can discuss the optimized design further.
