Title:
磁石の製造方法
Document Type and Number:
Japanese Patent JP6828723
Kind Code:
B2
Abstract:
A rotor of a rotary electric machine includes magnets arranged to face a winding. The magnets are movable relative to the winding upon the winding being energized. The magnets are arranged in a relative movement direction while magnetic polarities based on the magnets are alternately changed. Each magnet includes a first magnet member configured to generate magnet flux in accordance with a corresponding one of the polarities. The first magnet member has first magnetic orientations defined therein. Each magnet includes a second magnet member provided at a q-axis side end of the corresponding magnet located closer to a pole boundary. The second magnet member has second magnetic orientations defined therein. The second magnetic orientations intersect with the first magnetic orientations.
