Description

technical field

[0001] The present invention relates to a structure of an armature core for a rotary electric machine, and to an armature core for a rotary electric machine capable of improving the productivity of the armature core without impairing the good operating characteristics of the rotary electric machine. Background technique

[0002] Conventionally, a rotating electric machine is known in which a plurality of armature coils are wound around a plurality of magnetic pole teeth of an armature core to form an armature. The armature core has an annular back yoke and a plurality of magnetic pole teeth protruding from the back yoke at equal intervals. Spaces called slots are formed between the magnetic pole teeth, and armature coils are housed in the respective slots.

[0003] In order to prevent an increase in iron loss due to eddy currents, the armature core is composed of laminated steel sheets in which thin plate-shaped core pieces are laminated. Furthermore, it is...
