Loss of Permanent Magnet Magnetization Caused by Heat Exposure Loss of Magnetization Caused by Heat Exposure - Exposing a magnet to high temperatures can decrease its strength or permanently damage its structure. Usually this happens at very high temperatures, but for certain neodymium magnets this can happen as low as 60°C. Magnets are characterized by [...]
Customised Magnets for The Automotive Industry Automotive challenges The automotive industry operates according to the Just-In-Time (JIT) principle. One of the prerequisites for successful JIT production is a reliable supply chain of suppliers that meet the defined quality requirements. It is important that they can respond to changes in prices, specifications and forecasts. This keeps [...]
How are Magnets Used in the Automotive Industry? Vehicles need to be safer and more efficient than ever. Magnets are used in the automotive industry to achieve these goals and ensure a smoother car experience for us all. Find out more about how exactly they’re used and why they’re important not only for vehicle safety [...]
Where are Samarium Cobalt Magnets Useful? All the information you need to be an informed buyer of Samarium Cobalt Magnets right here, for free! Samarium Cobalt Magnets are among the second most common rare earth magnets. They can be used in temperatures on both the hottest and coldest end of the spectrum (although some swings [...]
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 [...]
Radiation Ring Magnet Sintered NdFeB magnetic ring is a new product developed in recent years. It is mainly used in high-performance permanent magnet motors and sensors. In the application of permanent magnet motors, sintered NdFeB magnetic tiles are usually bonded into a ring, which has natural disadvantages: Since the processing of the tile-shaped magnet belongs [...]
Eddy Current Loss of Rare Earth Permanent Magnet Both samarium cobalt and neodymium iron boron are metal materials. Due to the good electrical conductivity of metal materials, the resistivity is very low. This is not a good thing for rotating machinery such as motors, because it will bring eddy currents to rotating machinery Loss, causing [...]
Magnetic Materials in Linear Motors Linear motor is a kind of transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion. It can be regarded as a rotating motor that is radially dissected into a plane (that is, a rotating motor is flattened, and works the same). Linear motors [...]
