Frequently Asked Questions

1. Why can't I select a Magnetic Coupling simply by motor power?

Motor power alone does not determine the required Magnetic Coupling. The manufacturer also needs to consider rotational speed, operating torque, peak or starting torque, load characteristics, shaft dimensions, and operating conditions. For example, two 30 kW motors operating at different speeds can require different torque capacities. For this reason, a proper Permanent Magnetic Coupling Manufacturer China should calculate the required transmission torque from the complete operating conditions rather than selecting a product only from the motor's kW rating.

2. Why can a Magnetic Coupling become decoupled or appear to lose magnetic force during operation?

Decoupling does not automatically mean that the magnets are defective. Excessive load, abnormal starting conditions, blocked equipment, excessive torque demand, unsuitable operating speed, or overheating can cause the magnetic coupling to lose synchronization. Before blaming the product, check the actual operating torque and temperature against the manufacturer's specifications. During procurement, ask the supplier to specify the rated torque, maximum allowable torque, decoupling torque, operating temperature, and recommended overload protection so you understand the conditions under which the coupling is designed to operate.

3. Can Chinese Magnetic Coupling manufacturers produce non-standard shaft sizes and mounting dimensions?

Many Chinese manufacturers can provide OEM and customized Magnetic Couplings, but the level of customization differs between suppliers. If your equipment has a non-standard shaft diameter, unusual flange, limited installation space, special center distance, or specific torque requirement, send the original mechanical drawing whenever possible. Also ask whether the supplier will redesign and verify the magnetic circuit or only modify the mechanical dimensions. For a genuine Custom Magnetic Coupling Manufacturer China project, both the mechanical structure and magnetic performance should be considered together.

4. How should I choose the magnet and containment-shell material for a high-temperature Magnetic Coupling?

High-temperature applications require more than simply choosing the strongest magnet. The magnet's allowable working temperature, containment-shell material, shell thickness, rotational speed, heat generation, and surrounding environment all need to be evaluated. NdFeB is widely used, but certain high-temperature applications may require a different magnetic material depending on the operating temperature and performance requirements. The containment shell also affects magnetic transmission and heat generation. Therefore, give the Chinese supplier the actual continuous operating temperature, maximum temperature, RPM, and torque instead of simply describing the application as "high temperature."

5. Can Chinese Magnetic Coupling manufacturers provide OEM or replacement solutions for imported equipment?

Yes, customized and replacement projects are common sourcing requirements, but the supplier needs sufficient technical information to reproduce the required performance. Instead of sending only a photo of the imported coupling, provide the original model, drawing, dimensions, torque, RPM, materials, working temperature, application, and any known operating problems. The manufacturer can then evaluate the mechanical dimensions and magnetic requirements and develop a sample for testing. For critical equipment, it is safer to validate the replacement sample under actual operating conditions before moving to mass production. This approach is especially useful when looking for an OEM Magnetic Coupling Supplier China or a China manufacturer for imported-equipment replacement.
