What Is Magnetic Drive? How Does It Work? Quick Answer: What is a Magnetic Drive & How Does It Work? The Definition: A magnetic drive (such as a Hard Disk Drive or HDD) is a non-volatile, secondary storage device that uses spinning flat circular platters coated with a magnetic material to store digital data permanently. [...]
2026 Magnet Report: Rare Earths & Supply Chain Truths In 2026, the global magnet industry stands at a critical crossroads defined by resource constraints, technological bifurcation, and geopolitical restructuring. Demand from humanoid robots and high-performance electric drives is rapidly reshaping the global supply chain. We are entering a hybrid era: rare earth magnets continue to [...]
Why do Permanent Magnet Motors Demagnetize? A permanent magnet VSD (Variable Speed Drive) air compressor runs for less than two years. Then, it suddenly has unexplained high current and frequent inverter overload alarms. When checked, the magnets’ magnetic flux density has dropped by nearly 30%. This problem is common. Demagnetization is the most hidden failure [...]
Arc Magnet vs Block Magnet: Key Differences in Motor Applications In permanent magnet motor design, magnet shape directly affects motor efficiency, torque performance and manufacturing cost. Arc magnets and block magnets are the two most widely used magnet types for motors. They can be manufactured from identical magnetic materials. However, differences in air gap, magnetic [...]
How Segmented Magnets Reduce Eddy Current Loss Magnet segmentation is one of the most effective solutions to suppress eddy current loss in high-speed permanent magnet motors. As modern motors continue trending toward higher rotating speeds and higher operating frequencies, eddy current loss has become a critical bottleneck restricting motor efficiency, thermal stability, and service life. [...]
What is Passivation for NdFeB Magnets? NdFeB magnets have become the most widely used rare earth permanent magnets in modern industry due to their exceptional magnetic performance. However, because of the inherent characteristics of the material itself, NdFeB magnets are highly susceptible to oxidation and corrosion when exposed to humid environments, oxygen, acids, or alkalis. [...]
NEODYMIUM POT MAGNETS High Performance Pot Magnets Pot magnets are mighty magnets enclosed in a metal housing. They are commonly used to increase the magnet’s holding power and prevent it from being damaged. Being housed, the magnet can bear more pulling forces. Pot magnets can be used where adequate adhesion is needed. They are also [...]
NEODYMIUM SPHERE MAGNETS High Performance Ball Magnets The sphere magnets are powerful spherical magnets designed to ensure the even distribution of magnetic force. Hence, they can easily attach and hold several objects. They are more appropriately used for creative models, keeping documents, and constructing amusing stress-relief toys. However, they cannot be used for children’s toys. [...]
NEODYMIUM COUNTERSUNK MAGNETS High Performance Countersunk Magnets Neodymium countersunk magnets are high-performance magnets uniquely shaped to allow secure mounting by screws or bolts. The unique countersink hole design allows the magnet to be fitted flush without protruding from the surface. Besides the standard round form, they come in square, single-hole, or double-hole, thus finding a [...]
NEODYMIUM ARC MAGNETS High Performance Segment Magnets Neodymium arc magnets have an irreplaceable advantage in motor applications because of their unique, curved shape. They provide a strong and stable magnetic field in the rotation system, and such special size and shape make them indispensable in applications that require high precision. Neodymium arc magnets Arc Magnets [...]
