Combination of stator core for an electrical machine and a stator core manufacturing

摘要

A stator core (20) and manufacturing frame (40) combination, a stator core plate punching member (30), and methods of rolling a core body (22) without risk of significant damage to the core body (22) are provided. The combination preferably includes a stator core (20) having a substantially cylindrical and elongate core body (22). The core body (22) preferably includes a plurality of plate punching members (30). Each of the plurality of plate punching members (30) has a substantially smooth outer surface (32). The combination also preferably includes a manufacturing frame (40) positioned to substantially underlie the core body (22). The frame (40) preferably includes a plurality of spaced-apart rollers (45) each positioned to contact the substantially smooth outer surface (32) of each of the plurality of place punching members (30).
