図１及び図２に示すように、実施の形態の磁石埋込型回転子１０の回転子鉄心１は、薄い珪素鋼板（磁性体）を多数積層して円柱状に形成されている。回転子鉄心１の中心に形成された軸孔１ａには、図示しないシャフトが圧入され固定される。   As shown in FIGS. 1 and 2, the rotor core 1 of the magnet-embedded rotor 10 according to the embodiment is formed in a cylindrical shape by laminating a large number of thin silicon steel plates (magnetic bodies). A shaft (not shown) is press-fitted and fixed in the shaft hole 1 a formed at the center of the rotor core 1.

回転子鉄心１の外縁部には、周方向幅Ｈａ、径方向幅Ｈｂの長方形の、複数（８個）の磁石埋込孔１ｂが、環状に所定間隔で配置されている。回転子鉄心１の磁石埋込孔１ｂの外周側には、磁極部１ｃが形成されている。   On the outer edge of the rotor core 1, a plurality of (eight) magnet embedding holes 1b having a circumferential width Ha and a radial width Hb are annularly arranged at predetermined intervals. A magnetic pole portion 1 c is formed on the outer peripheral side of the magnet embedded hole 1 b of the rotor core 1.

図１〜図５に示すように、実施の形態の磁石保持枠２は、カシメ部２ｆが設けられた横枠２ａと、保持部２ｇが設けられた２本の平行な縦枠２ｂと、頭部枠２ｃと、を有し、夫々の端部同士が接続されて長方形に形成されている。   As shown in FIGS. 1 to 5, the magnet holding frame 2 of the embodiment includes a horizontal frame 2a provided with a crimping portion 2f, two parallel vertical frames 2b provided with a holding portion 2g, and a head. Part frame 2c, and each end part is connected and formed in the rectangle.

磁石保持枠２の内幅Ｈｃは、矩形板状の永久磁石３の横幅Ｈｄと同一であり、２本の縦枠２ｂの保持部２ｇ先端間の幅Ｈｆ（図２参照）は、永久磁石３の横幅Ｈｄよりも小さくなっていて、永久磁石３は、磁石保持枠２の縦枠２ｂ間に挿入され、縦枠２ｂ及び保持部２ｇにより側端部を支持されて、磁石保持枠２内に保持される。実施の形態では、磁石保持枠２の内側高さＨｋは、永久磁石３の高さＨｅの７倍となっていて、７枚の永久磁石３が磁石保持枠２内に隙間なく嵌め込まれる。永久磁石３と磁石保持枠２とを、接着剤により接着することが望ましい。   The inner width Hc of the magnet holding frame 2 is the same as the horizontal width Hd of the rectangular plate-shaped permanent magnet 3, and the width Hf (see FIG. 2) between the tips of the holding portions 2 g of the two vertical frames 2 b is equal to the permanent magnet 3. The permanent magnet 3 is inserted between the vertical frames 2 b of the magnet holding frame 2, and the side ends are supported by the vertical frames 2 b and the holding portions 2 g, so that the magnet holding frame 2 has a horizontal width Hd. Retained. In the embodiment, the inner height Hk of the magnet holding frame 2 is seven times the height He of the permanent magnet 3, and the seven permanent magnets 3 are fitted into the magnet holding frame 2 without a gap. It is desirable to bond the permanent magnet 3 and the magnet holding frame 2 with an adhesive.

磁石保持枠２の外幅Ｈｇは、回転子鉄心１の磁石埋込孔１ｂの周方向幅Ｈａと同一であり、永久磁石の厚さ及び磁石保持枠２の厚さＨｊは、磁石埋込孔１ｂの径方向幅Ｈｂと同一となっている。磁石保持枠２の高さＨｍは、回転子鉄心１の高さＨｎよりも大きくなっている。また、頭部枠２ｃの横幅Ｈｐは、磁石保持枠２の外幅Ｈｇよりも大きく、頭部枠２ｃの厚さＨｑは、永久磁石の厚さ及び磁石保持枠２の厚さＨｊよりも大きくなっている。   The outer width Hg of the magnet holding frame 2 is the same as the circumferential width Ha of the magnet embedding hole 1b of the rotor core 1, and the thickness of the permanent magnet and the thickness Hj of the magnet holding frame 2 are equal to the magnet embedding hole. It is the same as the radial width Hb of 1b. The height Hm of the magnet holding frame 2 is larger than the height Hn of the rotor core 1. The lateral width Hp of the head frame 2c is larger than the outer width Hg of the magnet holding frame 2, and the thickness Hq of the head frame 2c is larger than the thickness of the permanent magnet and the thickness Hj of the magnet holding frame 2. It has become.

７枚の永久磁石３を枠内に保持した磁石保持枠２を、横枠２ａ側から回転子鉄心１の磁石埋込孔１ｂ内に挿入して埋め込み、頭部枠２ｃを回転子鉄心１の一端に当接させ、回転子鉄心１の他端から突出した横枠２ａのカシメ部２ｆをカシメれば、珪素鋼板を多数積層して形成された回転子鉄心１が一体に締結されると共に、永久磁石３が磁石埋込孔１ｂ内に固定され、図１に示すような、実施の形態の磁石埋込型回転子１０が完成する。   The magnet holding frame 2 holding the seven permanent magnets 3 in the frame is inserted and embedded in the magnet embedding hole 1b of the rotor core 1 from the side of the horizontal frame 2a, and the head frame 2c is embedded in the rotor core 1. When the caulking portion 2f of the horizontal frame 2a protruding from the other end of the rotor core 1 is brought into contact with one end, the rotor core 1 formed by laminating a large number of silicon steel plates is integrally fastened, The permanent magnet 3 is fixed in the magnet embedding hole 1b, and the magnet embedding type rotor 10 of the embodiment as shown in FIG. 1 is completed.

以上説明したように、実施の形態の磁石埋込型回転子１０は、従来のリベットピンの役割をする磁石保持枠２が、磁石埋込孔１ｂに挿入されるので、リベットピン用の挿入孔を必要としない。また、永久磁石３の埋め込み工程とリベットピンの挿入工程を、１工程で行なうことができ、組立工数を削減することができる。また、リベットピン用の挿入孔を回転子鉄心１に配置する必要がないので、磁石埋込孔１ｂの配置位置に制約がなくなり、設計の自由度が向上する。   As described above, in the magnet-embedded rotor 10 according to the embodiment, since the magnet holding frame 2 serving as a conventional rivet pin is inserted into the magnet-embedding hole 1b, the insertion hole for the rivet pin is used. Do not need. Further, the step of embedding the permanent magnet 3 and the step of inserting the rivet pin can be performed in one step, and the number of assembly steps can be reduced. Further, since there is no need to arrange the insertion hole for the rivet pin in the rotor core 1, the arrangement position of the magnet embedding hole 1b is not restricted, and the degree of freedom in design is improved.

また、磁石保持枠２の横枠２ａ及び頭部枠２ｃが、永久磁石３の軸方向の動きを拘束するので、永久磁石３の抜け止めのための、従来の端板を必要としない。また、従来、端板をドリルで削ることにより行っていた回転子のバランス調整は、横枠２ａ及び頭部枠２ｃをドリルで削ることにより行なうことができる。   Further, since the horizontal frame 2a and the head frame 2c of the magnet holding frame 2 restrain the movement of the permanent magnet 3 in the axial direction, a conventional end plate for preventing the permanent magnet 3 from coming off is not required. Conventionally, the balance adjustment of the rotor, which has been performed by cutting the end plate with a drill, can be performed by cutting the horizontal frame 2a and the head frame 2c with a drill.

また、磁石保持枠２は、縦枠２ｂ及び保持部２ｇにより永久磁石３の側端部のみを支持する構造であり、永久磁石３の表裏の面を支持する壁などを有していないので、永久磁石３を、磁石保持枠２に表裏両側から挿入することができる。また、磁石保持枠２は、永久磁石３の表裏の面を支持する壁などを有していないので、渦電流による損失の発生を防ぐことができる。   In addition, the magnet holding frame 2 has a structure that supports only the side end portions of the permanent magnet 3 by the vertical frame 2b and the holding portion 2g, and does not have walls or the like that support the front and back surfaces of the permanent magnet 3. The permanent magnet 3 can be inserted into the magnet holding frame 2 from both the front and back sides. Moreover, since the magnet holding frame 2 does not have walls or the like that support the front and back surfaces of the permanent magnet 3, it is possible to prevent loss due to eddy currents.
