Original Abstract Submitted

a rotary electric machine includes a stator including a stator core and stator coils, which is cylindrical centered on an axis and has no slots, and a rotor disposed radially inward of the stator and including a rotor core and permanent magnets. (a) the stator coil is fixed to the inner peripheral surface inside the stator core. (b) the stator coil has coil end portions protruding outward from both end portions of the stator core in the direction of the axis cl. (c) in the direction of the axis cl, the length of the rotor core and the permanent magnets is longer than the length of the stator core, and the rotor core and the permanent magnets are arranged at positions including the stator core.
