Document Type and Number:
Japanese Patent JP6606027
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine performing variable speed drive from a low speed rotation to a high speed operation capable of preventing reduction of output.SOLUTION: The rotary electric machine includes a permanent magnet which has a composition containing at least one element selected from rare-earth elements. The residual magnetization of the permanent magnet is 1.16T or more. The coercive force Hcj on an M-H curved line of the permanent magnet is 1000 kA/m or more. The recoil permeability of the permanent magnet on a B-H curved line is 1.1 or more.SELECTED DRAWING: Figure 1
