Description
【０００１】[0001]
本考案は、産業用機器の駆動源に使用されるＡＣサーボモータなどの電動機の 回転子に関するものである。 The present invention relates to a rotor of an electric motor such as an AC servo motor used as a drive source for industrial equipment.
【０００２】[0002]
近年、産業用機器に使用される電動機は機器の高出力化，高速化に伴い、ます ます高トルク，高回転が要求される傾向にある。 In recent years, electric motors used in industrial equipment are required to have higher torque and higher rotation speed as the equipment has higher output and higher speed.
【０００３】 以下に、従来の電動機の回転子について説明する。 従来、この種の高トルク，高回転用に使用されるＡＣサーボモータなどの電動機 の回転子（図示せず）は、回転子鉄心の外周に複数の永久磁石を接着固定し、さ らに前記永久磁石の外周を樹脂含浸ガラステープで巻回固着あるいは前記永久磁 石の外周部を非磁性の薄金属管でおおうなどして、電動機の高速回転時の永久磁 石の飛散防止を行っている。The rotor of a conventional electric motor will be described below. Conventionally, a rotor (not shown) of an electric motor such as an AC servo motor used for high torque and high rotation of this kind has a plurality of permanent magnets bonded and fixed to the outer circumference of a rotor core. The outer circumference of the permanent magnet is wrapped and fixed with resin-impregnated glass tape, or the outer circumference of the permanent magnet is covered with a non-magnetic thin metal tube to prevent scattering of the permanent magnet during high-speed rotation of the motor. .
【０００４】[0004]
しかしながら上記の従来の回転子構成では、永久磁石の接着強度の補強のため に、該永久磁石の外周を樹脂含浸ガラステープで巻回して固着したり非磁性の薄 金属管をかぶせたりしており、多大の工数がかかり製作が困難なばかりか、前記 樹脂含浸ガラステープや非磁性の薄金属管が介在するために、回転子の磁気的ギ ャップをその分大きくとらなければならず、電動機特性に悪影響を与えるという 問題点を有している。 However, in the above-mentioned conventional rotor configuration, in order to reinforce the adhesive strength of the permanent magnet, the outer periphery of the permanent magnet is wrapped and fixed with a resin-impregnated glass tape or covered with a non-magnetic thin metal tube. Not only is it difficult to manufacture due to the large number of man-hours, but also because the resin-impregnated glass tape and the non-magnetic thin metal tube are interposed, the magnetic gap of the rotor must be increased accordingly and the motor characteristics It has a problem that it adversely affects.
【０００５】[0005]
本考案は上記従来の問題点を解決するもので、回転子鉄心の外周の所定位置に 配する複数の永久磁石を有する回転子において、前記永久磁石と前記回転子鉄心 とを固定する非磁性の金属体を前記永久磁石間に介在させるものとする。 The present invention solves the above-mentioned conventional problems, and in a rotor having a plurality of permanent magnets arranged at predetermined positions on the outer circumference of a rotor core, a non-magnetic material for fixing the permanent magnet and the rotor core to each other. A metal body is interposed between the permanent magnets.
【０００６】[0006]
この構成によって、前記永久磁石と回転子鉄心外周面との接着強度の補強をは かることにより堅牢な回転子を実現し、高速回転電動機の回転子を構成できる。 With this configuration, a strong rotor is realized by reinforcing the bonding strength between the permanent magnet and the outer peripheral surface of the rotor core, and the rotor of the high-speed rotary motor can be configured.

以下に本考案の一実施例について、図面を参照しながら説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【０００８】 図１は本考案の一実施例を示す回転子の側面半断面図であり、図２は図１のＡ −Ａ′断面図である。FIG. 1 is a side half sectional view of a rotor showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA ′ of FIG.
【０００９】 回転子鉄心５の外周に配した永久磁石３間のすき間形状と、前記回転子鉄心５ の外周に設けた逆テーパ溝４形状に対応した断面を有する非磁性の金属体２を軸 方向に挿入し、回転子鉄心５と永久磁石３とを固定して回転子１を構成している 。A non-magnetic metal body 2 having a cross section corresponding to the shape of the gap between the permanent magnets 3 arranged on the outer circumference of the rotor core 5 and the shape of the reverse taper groove 4 provided on the outer circumference of the rotor core 5 is used as the shaft. The rotor core 5 and the permanent magnets 3 are fixed to form the rotor 1.
【００１０】 また、前記非磁性の金属体２と永久磁石３および回転子鉄心５の接触面一面に 接着剤を塗布し、さらに前記三者の密着度を向上させてもよい。（図示せず）In addition, an adhesive may be applied to all contact surfaces of the non-magnetic metal body 2, the permanent magnet 3 and the rotor core 5 to further improve the degree of adhesion of the three. (Not shown)
【００１１】[0011]
以上のように本考案によれば、非磁性の金属体２を永久磁石３間と回転子鉄心 ５の外周に設けた逆テーパ溝４に嵌合させ相互の形状効果を利して、または接触 面に接着剤を塗布しさらに相互の密着度を向上させて、前記永久磁石３の接着強 度の補強をはかるので、従来例のような永久磁石の外周を巻回固着させる樹脂含 浸ガラステープや外周をおおう非磁性の薄金属管が不用となり、大巾な工数削減 と作業容易化がはかれ、かつ磁気的ギャップを極小にできるので電動機の特性向 上がはかれる。 As described above, according to the present invention, the non-magnetic metal body 2 is fitted between the permanent magnets 3 and the reverse taper groove 4 provided on the outer circumference of the rotor core 5 in order to obtain mutual mutual shape effect or contact. A resin-impregnated glass tape for fixing the outer circumference of a permanent magnet by winding it around, as in the conventional example, by applying an adhesive to the surface and further improving the mutual adhesion to strengthen the adhesive strength of the permanent magnet 3. The non-magnetic thin metal tube covering the outer circumference and the outer circumference is not required, which greatly reduces the number of man-hours and simplifies the work, and minimizes the magnetic gap, thus improving the characteristics of the electric motor.
