Abstract:
1. A stator structure of a rotating electrical machine, comprising: a magnet rotor; a plurality of magnetic teeth formed around the magnet rotor; a plurality of division cores each obtained by laminating electromagnetic steel plates; winding coils wound around the division cores via insulators, respectively; a pair of first and second bracket members that hold the plurality of division cores from front and back in a rotary shaft axial direction of the magnet rotor; and a fastening member that couples the first and second bracket members, wherein in the first bracket member is formed a first contact surface for striking one end face of each of the division cores to regulate so as to arrange the plurality of division cores annularly, in the second bracket is formed a second contact surface for striking other end face of each of the division cores to regulate, the first contact surface is a flat surface surface-contacting with one end face of each of the plurality of division cores and constitutes a reference plane to align the one end face of each of the plurality of division cores on a same plane, and the second contact surface is an inclined surface line-contacting with an edge of another end face of each of the plurality of division cores and formed of a deformation surface deformable to follow the other end face of each of the plurality of division cores.
