The invention provides a permanent magnet type motor and an electric power steering device. The side surface parts of the flange parts arranged on the plurality of tooth parts protrude towards the circumferential direction of a stator iron core, and are opposite to the side surface parts of the flange parts disposed on the adjacent tooth parts. The relationship 1 < = h/g < = 2 is satisfied, whereh is the radial height of the stator core provided on the side surface parts of the flange parts and g is the length of the magnetic air gap, and the relationship a/g > = 0.2 is satisfied, wherein a is the circumferential distance of the facing surface of the adjacent flange parts.

    在本发明的永磁体型电动机及电动助力转向装置中,设置于多个齿部的凸缘部的侧面部朝定子铁心的周向突出,与设置于相邻的齿部的凸缘部的侧面部相对,在设凸缘部的侧面部处的定子铁心的径向高度为h,磁性气隙的长度为g时,1≤h/g≤2的关系成立,且在设相邻的凸缘部相对的面的周向距离为a时,满足a/g≥0.2的关系。
