Rotary electric machine rotor and a method of manufacturing the same |
摘要 |
A rotary electric machine rotor comprises a rotary shaft which is formed with a plurality of protuberances projecting beyond a basic circle and extending in a lengthwise direction, and a core which is made of a plurality of core segments smaller in deformation resistance than that of the rotary shaft. The rotary shaft is plastically pressed into the core and has an annular groove formed at a position of the rotary shaft somewhat inward of an end face of the core. The core is plastically deformed and a part of the core is filled fully in the annular groove while axially pressing the core.
