How Are Samarium Cobalt Magnets Made SmCo magnets are rare earth magnets with high magnetic energy product and extremely low-temperature coefficient. Its maximum operating temperature can reach 350°C. When working at a temperature above 180℃, its maximum magnetic energy product (BHmax), coercivity, temperature stability, and chemical stability all exceed those of the NdFeB magnet. But [...]
How Are Ferrite Magnets Made? Ferrite magnet, also know as a ceramic magnet, is a kind of permanent magnet. Compared with other permanent magnets, ferrite magnets are hard and brittle and have lower magnetic energy. But it is not easy to demagnetize, not easy to be corroded, and low in price. Therefore, ferrite magnets are [...]
How Are Alnico Magnets Made? Alnico magnet was successfully developed in the 1930s. It is composed of aluminum, nickel, cobalt, iron, and other trace metal elements. Thanks to their high coercivity and high Curie temperature, Alnico magnets are widely used in many industrial and consumer products, such as motors, electric guitar pickups, microphones, sensors, speakers, [...]
The Many Types of EV Motors Electric vehicles (EVs) are becoming a popular green alternative to internal combustion engine (ICE) vehicles, the dominant driver for over 100 years. EVs operate via an electric motor powered by battery energy. There are various types of motors used for EVs. This article takes a look under the hood [...]
Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]
Motor Magnets for Electric Fans Ferrite magnets are fabricated by calcining the mixture of Barium or Strontium carbonate and iron to form a metallic oxide. Almost all of ferrite arc magnet is used in motor applications. As the core component of the permanent magnet direct current (DC) motor, ferrite arc magnet is commonly used in [...]
Ferrite Magnet for BLDC Ceiling Fan Motor, Fan Motor Ferrite Magnet Fan Motor Ferrite Magnet is a motor with a fan hub and blades. The slots are evenly distributed along the outer circumference of the fan hub. The blades are inserted into the slots. The blades and the fan hub are integrated by permanent connection [...]
Bladeless Fan BLDC Motor Magnets The Bladeless Fan BLDC Motor(24V), designed for a famous fan brand, provides the ideal flow for fan, with long life, low noise and other advantages.Power Motor has a mature Engineering customization platform and experienced engineers to provide huge various motor sample data for reference, customed motor solutions for your engineering [...]
Ferrite Magnets Replace Rare-earths in EV Motor Yaskawa says it has developed an electric vehicle (EV) motor that avoids the need for neodymium magnets, using much cheaper and easier-to-obtain ferrite magnets instead. The development is intended to reduce the company’s dependence on rare-earth materials, such as neodymium and dysprosium, whose prices have fluctuated widely in [...]
Permanent Magnet for Bladeless Fan Motor Working Principle of Bladeless Fan The working principle of bladeless fan exists the fundamental difference from conventional fan. The basic structure of bladeless fan generally consists of base and annular nozzle. Annular nozzle is placed on the base and its inner channel is connecting with the base. The base [...]
Superconducting Magnet Construction A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic [...]
How does Magnetism Affect a Watch? Watches can be adversely affected by magnetism and may gain or lose time. It is important not to leave a watch close to magnetic objects for a long periods. In particular, cell phones, television and PC speakers, magnetic necklaces, handbag clasps, hair-driers, electric razors, magnetic parts of refrigerators are [...]
