Title: Magnet and motor using it
Inventor: KOMURO MATAHIRO
IPC: H02K1/27
Filed: 2002-08-22
Abstract: <P>PROBLEM TO BE SOLVED: To provided a hard magnetic material having temperature coefficient for high and low coercive forces required for making the temperature dependency of magnetic characteristics small, when the hard magnetic material containing rare earth elements is used at a room temperature or above.  <P>SOLUTION: By adding an antiferromagnetic material and applying a cooling treatment in a magnetic field to the hard magnetic material, a magnetic coupling is generated between the hard magnetic material and the antiferromagnetic material. By inhibiting the magnetization of the hard magnetic material, the coercive force is increased, and the temperature coefficient of the coercive force is made small. By using it for a motor used in a temperature range not below the room temperature, a high torque is maintained up to high temperatures. The motor can especially be applied to industrial use, automotive components, a semiconductor transfer devices, and a generator.  <P>COPYRIGHT: (C)2004,JPO
