Alnico Magnets are Used for Electric Guitars In the vast universe of magnetism, Alnico magnets stand out for their remarkable properties and versatile applications. Comprised of aluminum (Al), nickel (Ni), cobalt (Co), and often including iron and other metals, Alnico magnets were developed in the 1930s and have since been integral to a myriad of [...]
Alnico vs. Rare Earth Magnets What is the difference between alnico and rare earth magnets? In the vast and evolving world of magnetics, Alnico and rare earth magnets stand out due to their distinct properties and wide range of applications. From basic science projects to complex industrial machinery, understanding the differences between these two types [...]
How to Protect the World's Strongest Magnets: Types of Neodymium Magnet Coatings Neodymium magnets, also known as NdFeB magnets, are among the most powerful permanent magnets available today. Comprising neodymium, iron, and boron, these magnets are essential in various applications ranging from consumer electronics to industrial machinery. However, their susceptibility to corrosion necessitates the use [...]
Magnetic Search Method to Find Stud When it comes to home improvement projects, few things can be as frustrating as trying to locate studs behind your walls. Whether you're hanging shelves, mounting a TV, or installing new fixtures, finding a solid anchor point is crucial for stability and safety. While stud finders have been a [...]
About N52 Grade Magnet Introduction N52 grade magnets are a grade of neodymium magnets. They are extremely strong magnets and as such have numerous merits in various industries. N52 magnets are generally considered to be the strongest grade of neodymium magnets readily available. There is a whole lot to learn about N52 grade magnets. Read [...]
Recycling Method of Sintered NdFeB Magnet Waste The waste recycling of NdFeB materials is usually divided into two directions: one is to separate and extract various elements, especially rare earth elements, in the NdFeB waste to prepare oxides or other compounds with a certain purity, which can be used as raw materials for different applications. [...]
MPCO Rare Earth Magnets The term rare earth magnet is a general term that refers to magnets that are made from alloys of rare earth elements, typically either neodymium iron boron or samarium cobalt. Both of these rare earth alloys are manufactured by a powdered metal process, but the resulting magnets have several distinct differences. [...]
MPCO Neodymium Capabilities Neodymium is the strongest available magnet alloy at up to 52MGOe. The use of Neodymium results in smaller, more cost-effective magnet solutions replacing older materials like Alnico and Ceramic in many applications. MPCO can help optimize performance and cost with Neo magnets in grades from 33 to 52MGOe and operating temperatures up [...]
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.
