Title:
MAGNET STRUCTURE, MANUFACTURING METHOD OF MAGNET STRUCTURE, AND MANUFACTURING METHOD OF ROTATING ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2020028185
Kind Code:
A
Abstract:
To provide a magnet structure with easy magnetization, a manufacturing method of the magnet structure, and a manufacturing method of a rotating electric machine.SOLUTION: In a magnet structure 1 and a manufacturing method thereof, the magnet structure 1 has a configuration including a plurality of magnet structural components 2, and the stacked plurality of magnet structural components 2 are restrained by restraints 4. In such a magnet structure 1, the plurality of magnet structural components 2 can be magnetized in a magnetizing step S1. In the magnetizing step S1, a magnetized object is the magnet structural component 2 smaller than the entire magnet structure 1. Therefore, a magnetizing device smaller than a magnetizing device that magnetizes the entire magnet structure 1 can be used, and the magnet structure 1 can be easily magnetized.SELECTED DRAWING: Figure 6
