AXIAL GAP ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide an axial gap rotary electric machine that is able to hinder an increase in the gap length of an axial rotor without an increase in the diameter of the axial rotor.SOLUTION: An axial gap rotary electric machine comprises: a stator 112; and an axial rotor 184 having an annual axial core 186 connected to a rotary shaft 122, and an axial permanent magnet 188 arranged opposite the stator 112 with a gap between them in the direction of the rotary shaft 122 on an outer peripheral part of the axial core 186. The height of the inner peripheral part of the end face 186a of the axial core 186, opposite the stator 112, is set less than that of the outer peripheral part. Thus, deformation of the axial core 186 in a direction in which a gap length increases due to centrifugal force during rotation is hindered.SELECTED DRAWING: Figure 1 【課題】アキシャルロータ径の増大を招くことなく、アキシャルロータのギャップ長の増大を抑制し得るアキシャルギャップ回転電機を提供する。【解決手段】ステータ１１２と、回転軸１２２に連結される環状のアキシャルコア１８６、及びアキシャルコア１８６の外周部に回転軸１２２方向においてステータ１１２とギャップを挟んで対向配置されたアキシャル永久磁石１８８を有するアキシャルロータ１８４を備える。アキシャルコア１８６のステータ１１２と反対側の端面１８６ａの内周部の高さは外周部に比べて低く設定され、回転時の遠心力によるギャップ長を拡大する方向のアキシャルコア１８６の変形を抑制する。【選択図】図１
