โ๏ธ Working Principle
The working principle of permanent magnet suction cups is based on the continuity principle of magnetic flux and the superposition principle of magnetic field. The magnetic circuit is designed as multiple magnetic systems, and through the relative motion of the magnetic systems, the magnetic field strength on the working magnetic pole surface is added or cancelled, thereby achieving the purpose of suction and unloading.
-
1Magnetic Suction State: Magnetic field lines come out of the N pole of the magnet, pass through the magnetic yoke, pass through the ferromagnetic workpiece, and return to the S pole through the magnetic yoke โ firmly attracting the workpiece to the working pole surface.
-
2Demagnetized / Unloading State: The magnetic pole enters a demagnetized state. Magnetic field lines no longer form a closed loop on the working pole surface, so almost no magnetic lines exit from the surface โ resulting in zero suction force and smooth workpiece release.
-
3Core Material: High-performance rare earth materials such as Neodymium Iron Boron (NdFeB) are used as the core, offering strong controllability, low production cost, corrosion resistance, and superior waterproof performance compared to electromagnetic suction cups.
๐ก These characteristics make permanent magnet suction cups widely used in fields such as mechanical processing and mold manufacturing.

โ Frequently Asked Questions
Q
How does a permanent magnet suction cup hold and release a workpiece?
A permanent magnet suction cup holds a workpiece by aligning its internal magnetic systems so that magnetic field lines pass through the ferromagnetic workpiece, creating a strong attraction force. To release the workpiece, the magnetic pole is switched to a demagnetized state by rotating the internal magnet assembly, which cancels the magnetic field on the working surface and eliminates the suction force.
Q
What material is used as the core of a permanent magnet suction cup?
High-performance rare earth material โ Neodymium Iron Boron (NdFeB) โ is commonly used as the core. It provides exceptional magnetic strength, strong controllability, corrosion resistance, and better waterproof performance compared to electromagnetic suction cups.
Q
What is the maximum load capacity and lifting height of these suction cups?
These permanent magnet suction cups support a lifting height range of 3 to 30 meters and can handle load increases of up to 1000 kg, making them suitable for heavy-duty industrial applications including steel structure installation and ship assembly.
Q
What are the advantages of permanent magnet suction cups over electromagnetic suction cups?
Permanent magnet suction cups offer several advantages over electromagnetic types: they do not require a continuous power supply to maintain holding force, they are more energy-efficient, they provide better corrosion resistance and waterproof performance, they have lower production costs, and they are safer in the event of a power failure since the magnetic force is not lost.
Q
In which industries are permanent magnet suction cups most commonly used?
Permanent magnet suction cups are most commonly used in the mechanical processing, mold manufacturing, steel structure manufacturing, automotive manufacturing, shipbuilding, and aerospace industries. They are also widely applied in logistics, warehousing, electronics assembly, and heavy equipment maintenance.
Q
Can permanent magnet suction cups be used for non-industrial everyday applications?
Yes. Beyond industrial use, permanent magnet suction cups are also applied in daily life scenarios such as home cleaning (windows, glass, floors), furniture decoration (mounting clocks and mirrors without drilling), electronic device brackets (for smartphones and tablets), automotive interior accessories, and even medical device support during surgical procedures.
