Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はリラクタンスモータの回転子に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a rotor for a reluctance motor.
従来の軸方向積層形リラクタンスモータの回転子の構造
を第５図に示す。２１は軸、２２は軸と平行に積層され
た積層体（鉄心）、２３は積層鉄心を固定するボルトで
ある。FIG. 5 shows the structure of a rotor of a conventional axially laminated reluctance motor. 21 is a shaft, 22 is a laminated body (iron core) laminated in parallel with the axis, and 23 is a bolt for fixing the laminated core.
この回転子は、突極構造になっており、突極部と凹極部
の磁気抵抗のちがいを利用して回転力を得ている。この
回転力を大きくするために、従来のリラクタンスモータ
は、第５図に示すように、極部の半径方向の磁気抵抗が
大きくなり、突極部の半径方向の磁気抵抗を小さくする
ために、軸２ｚに平行にケイ素鋼板を積層して形成され
ている。積層板相互および積層された鉄心２２と軸２ｚ
を固定するためにボルト２３が用いられている。This rotor has a salient pole structure, and obtains rotational force by utilizing the difference in magnetic resistance between the salient pole portion and the concave pole portion. In order to increase this rotational force, in the conventional reluctance motor, as shown in FIG. It is formed by laminating silicon steel plates parallel to the axis 2z. Laminated plates mutually and laminated core 22 and shaft 2z
Bolts 23 are used to fix the.
前記の如〈従来の軸方内積層形回転子は、回転子を軸方
向に積層する際に、積層板どうしを樹脂などで接着して
固定し、さらに、接着固定した積層板相互をボルトで固
定し、さらｌζ、積層板とシャフトとをボルトで固定し
ていたので、以下に述べる欠点が生じていた。As mentioned above, in conventional axially laminated rotors, when the rotor is laminated in the axial direction, the laminated plates are bonded and fixed together with resin etc., and then the adhesively fixed laminated plates are fixed together with bolts. Since the laminated plate and the shaft were fixed with bolts, the following disadvantages occurred.
モータの発生するトルクは、積層板の曲げ方向にかかる
ので、モータトルクにより積層板が第６図ζζ示すよう
に曲げられ、回転子の極が広がり、凹極部が狭くなる。Since the torque generated by the motor is applied in the bending direction of the laminated plate, the laminated plate is bent by the motor torque as shown in FIG.
このことは次のような不具合を生ずる。This causes the following problems.
■ リラクタンスモータの主要な特性は、突極部のイン
ダクタンスと凹極部のインダクタンスの比−こよって決
まる。従って積層板が広がってしまうと、突極部のイン
ダクタンスが低下し、これによりトルクが下る。■ The main characteristics of a reluctance motor are determined by the ratio of the inductance of the salient pole to the inductance of the concave pole. Therefore, when the laminated plate spreads, the inductance of the salient pole portion decreases, thereby decreasing the torque.
■ 積層板が振動し、モータの騒音の原因となる。■ Laminated plates vibrate, causing motor noise.
■ 回転子の凹凸により風損が生じる。。■ Windage loss occurs due to the unevenness of the rotor. .
才た、ボルトは、半径方向を向いているので、ボルトを
通して半径方向の磁束の通路ができてしまい、凹極部の
インダクタンスが増加し、トルクが低下する。Since the bolt is oriented radially, a radial magnetic flux path is created through the bolt, increasing the inductance of the concave pole and reducing the torque.
