Core having axially assembled core sub-parts and dynamo-electric machine member having the same

A dynamo-electric machine member for a dynamo-electric machine, the dynamo-electric machine member comprising:

• a core that includes a plurality of core sub-parts, which are assembled together in an axial direction of the core, wherein:
• at least two of the plurality of core sub-parts have at least one tooth;
• and
• each tooth has a tooth main body, which includes two tilted portions at two opposed circumferential ends, respectively, of the tooth main body, wherein each tilted portion is angled relative to a corresponding direction parallel to the axial direction of the core, so that a circumferential width of the tooth main body decreases in an assembling direction of the tooth;
• and
• a plurality of winding wires, each of which is wound around a corresponding one of the teeth of the core.

A core for a dynamo-electric machine, the core comprising a plurality of core sub-parts, which are assembled together in an axial direction of the core, wherein:

• at least two of the plurality of core sub-parts have at least one tooth;
• each tooth has an extended portion, which is located in a radial end of the tooth and is circumferentially extended from the rest of the tooth;
• and
• the extended portion of each tooth has at least one length decreasing portion, each of which reduces an axial length of the extended portion toward a circumferential end of the length decreasing portion.
