Neodymium magnets have the highest magnetic force among all magnets, and are used in drive motors of EVs and hybrids. Neodymium magnets must have high heat resistance properties and adding heavy rare earth (dysprosium and/or terbium) to it has been a conventional method to ensure high heat resistance.
However, heavy earth elements, also known as rare metals, are found unevenly around the world, and the use of it carries risks from the perspectives of stable procurement and material costs. Therefore, this is a major breakthrough on Honda’s part.
MPCO has been mass-producing neodymium magnets using the hot deformation method, which is different from the typical sintering production method. It enables nanometer-scale crystal grains to be well-aligned in order to realise a fine crystal grain structure that is around ten times smaller than that of a sintered magnet, which makes it possible to produce magnets with greater heat resistance properties. Block Neodymium Hybrid Vehicle Motor Magnets
The challenge to reduce the use of heavy rare earth metals and the cost of drive motors production has been met by Honda and Daido Steel by mass-producing neodymium magnets using the hot deformation method.
This method of neodymium magnet production enables nanometer-scale crystal grains to be aligned to realize a fine crystal grain structure that is approximately ten times smaller than that of a sintered magnet, which makes it possible to produce magnets with greater heat resistance properties.
Honda revised the shape of the magnet to make it fit in the drive motor of its hybrid vehicles while also redesigning the motor and the shape of the rotor to optimize the flow of the magnetic flux of the magnet.
The result is a hot deformed neodymium magnet with no heavy rare earth metal that provides torque and with heat resistance performance similar to a conventional magnet.
Honda will use the new hot deformed neodymium magnet on the Honda SPORT HYBRID i-DCD 2 system for the all-new FREED.
