用いて好適な回転電機用内部フレームに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an internal frame for a rotary electric machine suitable for use in a rotary electric machine such as a rotary solenoid and a motor.
一般に、ロータリソレノイドやモータ等で代表される回
転電機、特にインナロータ式の回転電機はヨークにコア
を取付け、このコアに絶縁を考慮したコイルを巻回して
界磁側の磁極を構成している。Generally, a rotary electric machine represented by a rotary solenoid or a motor, especially an inner rotor type rotary electric machine has a core attached to a yoke, and a coil in consideration of insulation is wound around the core to form a magnetic pole on the field side.
従来、このような界磁側の構造はコア部とヨーク部が一
体形状のケイ素鋼板等を積層し、コアケースを構成する
とともに、別部材による絶縁保護を図っていた。Conventionally, in such a structure on the field side, a silicon steel plate or the like having a core portion and a yoke portion integrally formed is laminated to form a core case, and insulation protection is achieved by a separate member.

第二に、ヨークの内径或は形状に制約があるため高密度
にコイルを巻くことが困難である。このため、コイルが
コアの軸方向に膨れ、回転電機そのものの小型化を図る
ことができない。Secondly, it is difficult to wind the coil with high density because the inner diameter or shape of the yoke is limited. Therefore, the coil swells in the axial direction of the core, and it is impossible to reduce the size of the rotating electric machine itself.
第三に、トルク特性等の特性変更を行いたい場合にはコ
アケースの形状、大きさ、さらには絶縁部材等を新たに
設計し直す必要があり、結局、金型も新規に製作しなけ
ればならず、少量多品種に適合しにくく、大幅なコスト
アップを招く。Thirdly, in order to change the characteristics such as torque characteristics, it is necessary to redesign the shape and size of the core case, and also the insulating member, etc. As a result, it is difficult to adapt to a large number of small-lot types, resulting in a significant cost increase.
本考案は上述した従来技術に存在する諸問題を解決した
新規な回転電機用内部フレームの提供を目的とするもの
