| 简介 |
Provided are a rare-earth magnet capable of realizing a high magnetic flux amount without using any back yoke, and a linear motor comprising a movable element using the rare-earth permanent magnet. A rare-earth permanent magnet-forming sintered body for forming a permanent magnet is integrally sintered while being formed into a given three-dimensional shape with a lengthwise cross-section having a first surface extending in a length direction thereof, a second surface lying at a distance from the first surface in a thickness direction thereof and extending in the length direction, and an edge surface of each of lengthwise opposite ends thereof. This sintered body is formed such that easy magnetization axes of the magnet material particles included in a central region thereof are oriented in such a manner as to be directed along an arch-shaped path. In a first end region, easy magnetization axes of the magnet material particles included therein are oriented in such a manner as to be directed along a path which enters an inside of the sintered body from the first surface and extends toward the second surface. In a second end region, easy magnetization axes of the magnet material particles included therein are oriented in such a manner as to be directed along a path which enters the inside of the sintered body from the second surface and extends toward the first surface. |
