What are Temperature Coefficients (α and β) of Permanent Magnets? A permanent magnet’s magnetic properties change as a variation of temperature. For a permanent magnet, remanence (Br) and intrinsic coercivity (Hcj or Hci) are two major parameters, it is important to consider their changes with corresponding temperature variation at work. In order to describe the [...]
Multi-pole Magnetic Rotor Assembly for USA Electric-motor Customer HSMAG has secured an order for the supply of 600 multi-pole Samarium Cobalt (SmCo) magnetic rotor assemblies annually to a USA prominent Electric-motor customer. The magnetic rotor order was placed at the end of 2018 with deliveries starting in 2019 and running for 10 years. The HSMAG [...]
Samarium Cobalt MATERIAL GRADES Known as Rare Earth magnets, Samarium Cobalt (SmCo) are alloys of the Lanthanide group of elements. SmCo magnets have been commercially available since the early 1970’s, first as a 1-5 Type alloy, and later with the introduction of the 2-17 type. Both alloys offer outstanding thermal stability and excellent corrosion resistance. [...]
Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles DEMETER – European Training Network for the Design and Recycling of Rare-Earth Permanent Magnet Motors and Generators in Hybrid and Full Electric Vehicles In 2010 the European Commission (EC) published a milestone report on Critical Raw Materials (CRM) for [...]
Bonded Magnets: A Versatile Class of Permanent Magnets Permanent magnets are ubiquitous in modern societies. Devices that use permanent magnets include motors, sensors, actuators and acoustic transducers. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment and more. It is estimated, for example, that a [...]

According to them, this magnet has the ability to create devices with amazing power efficiency and performance capabilities. This has [...]
SmCo Manufacturing Methods SmCo magnets are manufactured in the following forms: Sintered - fine SmCo powder is compacted in a die and then sintered, fusing the powder into a solid material. There are two forms of pressing - die pressing (which involves a hard die into which the powder is placed and then pressed), and [...]
