Rotary electric machine having a stator core formed with stacked thin sheets and aircraft using the rotary electric machine core

An aircraft comprising:

• a rotary electric machine including:
• a stator core;
• and
• two movable parts which are placed with the stator core interposed therebetween and rotate about an identical rotary shaft, wherein
• at least part of the stator core is formed by stacking thin sheets in a rotation direction of the two movable parts,
• the stator core has, at both ends, stator core retention portions extended in a direction parallel to surfaces thereof opposed to the two movable parts and perpendicular to the rotation direction of the movable parts,
• retention surfaces of the stator core retention portions at both ends are respectively fixed in contact with retention members,
• the retention surfaces of the stator core retention portions at both ends are formed to face toward each other, and
• stator core is fixed with tensile stress applied thereto.
