World's First Magnetic Field Orientation Controlling Neodymium Magnet

saves energy and improves motor performance by 20 to 30%

Nitto Denko Corporation (Head Office in Osaka, President Hideo Takasaki) has recently used its organic/inorganic hybrid technologies to successfully develop a unique type of neodymium magnet, the first of its kind in the world. By controlling magnetic field orientation the magnet is able to improve motor performance by 20 to 30% compared to conventional motors, while also contributing to motor miniaturization efforts.

[Development Details]
The neodymium magnet is a type of rare-earth magnet primarily composed of neodymium, iron, and boron. As a powerful permanent magnet, it is used in various products, from small electronics such as hard disk drives and mobile phones, to trains, automobiles, and robots. Currently more than half of all power generated around the world is consumed by motorized devices, so increasing the efficiency of motors will contribute a great deal to energy conservation efforts. Many such motors use magnets, which is why the demand for highly-efficient neodymium magnets continues to rise. Nitto Group has implemented new fields of growth known as Green (global environment), Clean (new energy), and Fine (life science). We have been developing technologies under these fields for the creation of new businesses, and by applying our organic/inorganic hybrid technology, we were able to develop a new type of neodymium magnet capable of increasing the performance of conventional motors.

[Product Features]
This sintered neodymium magnet is capable of controlling magnetic field orientation, something that conventional sintered neodymium magnets are unable to accomplish. Since its orientation control capability can increase the performance of conventional motors by 20 to 30%, our neodymium magnet can contribute significantly to the miniaturization and lightweight manufacture of motors. And since the magnet can be freely formed before the sintering process, post-sintering shaving tasks are no longer necessary, potentially increasing yield rate.
