Title:
STATOR PART OF ROTARY ELECTRIC MACHINE, AND DEVICE EQUIPPED WITH THE SAME
Document Type and Number:
Japanese Patent JP2020114056
Kind Code:
A
Abstract:
To provide a stator part, of a rotary electric machine, including a stator and capable of suppressing vibrations of the rotary electric machine by improving the rigidity of the stator part.SOLUTION: A stator part 3 of a rotary electric machine includes: a stator core 7 including yoke sections 7a each having a cylindrical shape and teeth sections 9 each projected from an inner surface of the yoke section 7a; a stator winding (not illustrated) in which a portion of each of the teeth sections 9 serves as a magnetic core; a stator core exterior body 1a having a cylindrical inner surface 1b in contact with a cylindrical outer surface 7b of the stator core 7; a cylindrical shape included in the stator core exterior body 1a; a configuration which includes polygonal outer surfaces 6 having polyhedron shapes at outer surfaces thereof respectively facing the cylindrical inner surfaces 1b included in the stator core exterior body 1a and in which the line segment direction of each ridge section 6b including a corner 6a of the polygonal outer surface 6 is the same as the axial direction of a virtual center axis 7d of the cylindrical shape of the stator core 7; and through holes 2 that are each positioned between the ridge section 6b and the cylindrical inner surface 1b and that penetrate in the same direction as the axial direction of the virtual center axis 7d.SELECTED DRAWING: Figure 1
