Electromagnets From Healthcare to Transportation In a world where technology and innovation continually redefine the boundaries of possibility, electromagnets play a pivotal yet often underappreciated role. Far from being confined to the realms of high-tech laboratories or industrial applications, electromagnets are integral to many aspects of our daily lives, from the healthcare we receive to [...]
Spreading magnets or Metal plate spreaders facilitate a safe and efficient removal of the steel plates from a pile. The magnetic flux of the spreader, generated by anisotropic ferrite magnets, penetrates individual plates causing that they are pushed away from each other. The gaps created between the plates allow removing them in an convenient way. [...]
What are magnetic fields? Simply speaking a magnetic field is the region around a magnet. Magnets are made out of mineral called magnetide (or lodestone) which has the property of attracting iron. Scientists use magnetic field lines to represent these magnetic fields. The magnetic field lines of a simple magnet are shown in the picture [...]
IPM vs SPM Electric Motors A PM motor can be separated into two main categories: surface permanent magnet motors (SPM) and interior permanent magnet motors (IPM) . Neither motor design type contains rotor bars. Both types generate magnetic flux by the permanent magnets affixed to or inside of the rotor. SPM motors have the magnets [...]
Difference Between Inline and Surface Mount NdFeB Magnets in PM Motors What is the difference between inline and surface mount design of NdFeB magnets for permanent magnet motors? A permanent magnet (PM) motor is a type of AC motor that uses permanent magnets embedded or attached to the surface of the motor rotor. Electric vehicles [...]
Effects of Magnetic Parameters on Permanent Magnet PM Motors How to measure the magnetic properties of magnet? Almost all magnet manufacturers use B-H curve testing equipment to get the demagnetization curve of magnet. This method is a closed circuit measurement, and an uniform cross-section sample is clamped between the faces of electromagnet. The testing sample [...]
Permanent Magnet Motor Operation Tips Key technical points for maintaining normal operation of permanent magnet motors Once the permanent magnet motor is demagnetized, basically the only option is to replace the motor; the cost of repair and a large amount of how to determine the permanent magnet motor demagnetized it, we go on to see. [...]
The “Center” of Permanent Magnet Motors – Permanent Magnets The development of permanent magnet motors is closely related to the development of permanent magnet materials. China is the first country in the world to discover the magnetic properties of permanent magnetic materials and apply them to practice. More than 2000 years ago, China made a [...]
Alignment Technique for Anisotropic Injection Magnets Overview: The Alignment Technique for Anisotropic Injection Magnets refers to a specific method used in the manufacturing process of anisotropic injection-molded magnets to achieve the desired magnetic alignment or orientation within the final magnet product. Anisotropic injection magnets are a type of permanent magnet known for having a preferred [...]
What is SmFeN Magnet SmFeN magnetic material uses abundant rare-earth Sm element instead of expensive elements of Nd, Dy, Co, etc, and is the most cost-effective rare earth permanent magnetic material. Compared with the bonded neodymium magnet, the bonded SmFeN magnet has higher magnetic properties and lower prices. Moreover, curie temperature, corrosion resistance, and thermal [...]
