Description

この発明は、モータおよびそれを用いた圧縮機に関する。   The present invention relates to a motor and a compressor using the motor.

従来、モータとしては、電磁鋼板を積層してロータコアを形成し、そのロータコアに永久磁石を星形に配置し、さらにその両端に磁石飛び出し防止用の端板を被せ、それらにリベットを軸方向に貫通させて締結することによりロータを一体化したものがある(例えば、特許第３３９７０１９号(特許文献１)参照)。   Conventionally, as a motor, a rotor core is formed by laminating electromagnetic steel plates, permanent magnets are arranged in a star shape on the rotor core, and end plates for preventing magnet jumping are put on both ends of the rotor core, and rivets are axially attached to them. There is one in which the rotor is integrated by passing through and fastening (for example, see Japanese Patent No. 3397019 (Patent Document 1)).

一般に、ロータコアを締結するリベットには鉄が用いられるが、磁束がリベットを通過するときにリベット内に鉄損が生じて効率が低下する。また、中空または円筒状のリベットを使用した場合も、磁束の流れを阻害するため、効率が低下する。さらに、リベット、端板が磁性体の場合、極間の漏れ磁束により効率が低下する。一方、リベットの位置は、ロータの外周に近い位置に設けることで、ロータ全体に均等に締結力が加わるため、ロータの剛性向上する。しかし、星形に配置された磁石よりも半径方向外側の磁束密度の高いところにあるため、上記のようにトルク低下や効率低下の影響が大きくなるという問題がある。
特許第３３９７０１９号 Generally, iron is used for the rivet for fastening the rotor core, but when the magnetic flux passes through the rivet, iron loss occurs in the rivet and the efficiency is lowered. Further, when a hollow or cylindrical rivet is used, the flow of magnetic flux is obstructed, so that the efficiency is lowered. Further, when the rivet and the end plate are made of a magnetic material, the efficiency is lowered due to the leakage magnetic flux between the poles. On the other hand, by providing the rivet at a position close to the outer periphery of the rotor, the fastening force is evenly applied to the entire rotor, so that the rigidity of the rotor is improved. However, since the magnetic flux density is higher on the outer side in the radial direction than the magnets arranged in a star shape, there is a problem that the influence of torque reduction and efficiency reduction is increased as described above.
Japanese Patent No. 3397019

そこで、この発明の課題は、トルク低下や効率低下を抑えつつロータの剛性を高めることができるモータを提供することにある。   Therefore, an object of the present invention is to provide a motor that can increase the rigidity of the rotor while suppressing a decrease in torque and a decrease in efficiency.

And tightening the rotor core with the fastening member suppresses torque reduction and efficiency reduction without hindering the flow of magnetic flux, and the rotor core is fastened by the fastening member on the outer peripheral side, so that the rigidity of the rotor is reduced. Can be increased.

また、一実施形態のモータでは、上記締結部材は、上記ロータコアの電気角６０°〜１６０°の範囲内にある。   In one embodiment of the motor, the fastening member is in the range of 60 ° to 160 ° electrical angle of the rotor core.

Reduction and efficiency reduction can be effectively suppressed.

また、一実施形態のモータでは、上記締結部材は、中空の部材または円筒状の部材からなる。   Moreover, in the motor of one Embodiment, the said fastening member consists of a hollow member or a cylindrical member.

上記実施形態によれば、中空の部材または円筒状の部材からなる締結部材を用いることによって、軸方向に貫通する穴を設けても、磁束密度の低い部分を貫通する締結部材が磁束の流れを阻害することがない。   According to the above-described embodiment, by using a fastening member made of a hollow member or a cylindrical member, the fastening member that penetrates a portion having a low magnetic flux density flows a magnetic flux even if a hole that penetrates in the axial direction is provided. There is no hindrance.

また、一実施形態のモータでは、上記のいずれか１つのモータを搭載したことを特徴とする。   In one embodiment, any one of the above motors is mounted.

上記構成によれば、効率のよい信頼性の高い圧縮機を実現できる。   According to the above configuration, an efficient and highly reliable compressor can be realized.

また、一実施形態のモータによれば、ロータコアの電気角６０°〜１６０°の範囲内の磁束の少ない領域で、締結部材を軸方向に貫通して締結することによって、トルク低下や効率低下を効果的に抑えることができる。   In addition, according to the motor of one embodiment, torque reduction and efficiency reduction can be achieved by penetrating the fastening member in the axial direction and fastening in a region where the magnetic angle of the rotor core is within a range of 60 ° to 160 ° with little magnetic flux. It can be effectively suppressed.

また、一実施形態のモータによれば、中空の部材または円筒状の部材からなる締結部材を用いることによって、軸方向に貫通する穴を設けても、締結部材が磁束の流れを阻害することがない。   Moreover, according to the motor of one embodiment, by using a fastening member made of a hollow member or a cylindrical member, even if a hole penetrating in the axial direction is provided, the fastening member can inhibit the flow of magnetic flux.

It is pierced and fastened. The through holes 131b of the rotor core 131 are provided on the radially outer side of the permanent magnet 132 and at positions where the electrical angle is approximately 90 °.

図２はこの発明の実施の他の形態のモータＢの要部の平面図を示している。   FIG. 2 shows a plan view of the main part of a motor B according to another embodiment of the present invention.

図２に示すモータＢは、電磁鋼板が積層された円柱形状のロータコア２３１に４つの永久磁石２３２が周方向にかつ正方形状(凸多角形状)配列されたロータ２３０と、そのロータ２３０の外周側を囲うステータ２４０とを備えている。上記ロータコア２３１の軸穴２３１aに回転軸２１０を挿入して嵌合している。上記ステータ２４０は、６つのティース２４１aが内周側に設けられたステータコア２４１と、上記６つのティース２４１aに夫々巻回されたコイル(図示せず)とを有している。   A motor B shown in FIG. 2 includes a rotor 230 in which four permanent magnets 232 are arranged in a circumferential direction and in a square shape (convex polygonal shape) on a cylindrical rotor core 231 in which electromagnetic steel plates are laminated, and an outer peripheral side of the rotor 230. And a stator 240 that surrounds. The rotating shaft 210 is inserted and fitted into the shaft hole 231a of the rotor core 231. The stator 240 includes a stator core 241 provided with six teeth 241a on the inner peripheral side, and coils (not shown) wound around the six teeth 241a.

また、上記締結部材の一例としてのリベット２３３を、ロータコア２３１に軸方向に設けられた貫通孔２３１bに貫通させて締結している。このロータコア２３１の貫通孔２３１bは、永久磁石２３２の半径方向外側、かつ、電気角が略９０°の位置に夫々設けられている。   A rivet 233 as an example of the fastening member is passed through a through hole 231b provided in the axial direction in the rotor core 231 and fastened. The through holes 231b of the rotor core 231 are provided on the radially outer side of the permanent magnet 232 and at positions where the electrical angle is approximately 90 °.

また、図３はモータＡのステータコア表面とロータコア表面の磁束の分布を示し、図４はモータＢのステータコア表面とロータコア表面の磁束の分布を示している。図３,図４に示すθは、１つの永久磁石が配置された機械角０°〜９０°の範囲において、電気角０°〜１８０°となる。   3 shows the distribution of magnetic flux on the stator core surface and the rotor core surface of the motor A, and FIG. 4 shows the distribution of magnetic flux on the stator core surface and the rotor core surface of the motor B. The θ shown in FIGS. 3 and 4 is an electrical angle of 0 ° to 180 ° in a mechanical angle range of 0 ° to 90 ° where one permanent magnet is arranged.

図５において、横軸は電気角を表し、縦軸はロータコア表面の磁束密度を表しており、ロータコアの電気角６０°〜１６０°の範囲は、他の部分よりも磁束密度の低い領域である。このように、ロータに周方向かつ凸多角形状に配列される磁石の数によらず、電気角６０°〜１６０°の範囲で締結部材を設ければ同様の効果が得られる。   In FIG. 5, the horizontal axis represents the electrical angle, the vertical axis represents the magnetic flux density on the rotor core surface, and the range of the electrical angle of 60 ° to 160 ° of the rotor core is a region where the magnetic flux density is lower than other portions. . Thus, the same effect can be obtained if the fastening member is provided in the electrical angle range of 60 ° to 160 ° regardless of the number of magnets arranged in the circumferential direction and in the convex polygonal shape on the rotor.

上記構成のモータによれば、ロータコア１３１,２３１に周方向かつ凸多角形状に配列された磁石１３２,２３２と、ロータコア１３１の磁石１３２,２３２の半径方向外側の領域内で、磁束密度が高い部分と低い部分のうちの低い部分を軸方向に貫通するリベット(締結部材)１３３,２３３により、ロータコア１３１,２３１を締結することによって、磁束の流れを阻害することなくトルク低下や効率低下を抑えと共に、ロータコア１３１,２３１が外周側でリベット(締結部材)１３３,２３３により締結されるので、ロータ１３０,２３０の剛性を高めることができる。   According to the motor having the above configuration, the magnets 132 and 232 arranged in the circumferential direction and the convex polygonal shape on the rotor cores 131 and 231, and the portion where the magnetic flux density is high in the radially outer region of the magnets 132 and 232 of the rotor core 131. By fastening the rotor cores 131 and 231 with the rivets (fastening members) 133 and 233 that penetrate the lower part of the lower part in the axial direction, torque reduction and efficiency reduction can be suppressed without hindering the flow of magnetic flux. Since the rotor cores 131 and 231 are fastened by rivets (fastening members) 133 and 233 on the outer peripheral side, the rigidity of the rotors 130 and 230 can be increased.

また、上記ロータコア１３１,２３１の電気角６０°〜１６０°の範囲内の磁束の少ない領域で、リベット(締結部材)１３３,２３３を軸方向に貫通して締結することによって、磁束の流れを阻害することなくトルク低下や効率低下を効果的に抑えることができる。   Further, the flow of magnetic flux is obstructed by penetrating rivets (fastening members) 133 and 233 in the axial direction and fastening them in an area where the magnetic angle of the rotor cores 131 and 231 is small within an electric angle range of 60 ° to 160 °. Torque reduction and efficiency reduction can be effectively suppressed without doing so.

上記実施の形態では、電磁鋼板が積層された円柱形状のロータコア１３１,２３１に４つの永久磁石１３２,２３２が周方向にかつ正方形状(凸多角形状)配列されたロータ１３０,２３０を有するモータについて説明したが、モータの構成はこれに限らず、円柱形状のロータコアに周方向にかつ凸多角形状に磁石が配列されたロータを有するモータであればよく、磁石の数は限定されない。また、全ての磁石の半径方向外側に締結部材はなくともよく、少なくとも３つの締結部材によりロータコアが締結されていればよい。   In the above embodiment, a motor having rotors 130 and 230 in which four permanent magnets 132 and 232 are arranged in a circumferential shape and in a square shape (convex polygonal shape) on cylindrical rotor cores 131 and 231 in which electromagnetic steel plates are laminated. Although described, the configuration of the motor is not limited to this, and any motor may be used as long as it has a rotor in which magnets are arranged in a circumferential shape and a convex polygonal shape on a cylindrical rotor core, and the number of magnets is not limited. Moreover, there is no need to have a fastening member on the outer side in the radial direction of all the magnets, and it is sufficient that the rotor core is fastened by at least three fastening members.

また、上記実施の形態では、締結部材としてリベット１３３,２３３を用いたが、締結部材はこれに限らず、ボルトとナット等の他の締結部材を用いてもよい。   In the above embodiment, the rivets 133 and 233 are used as the fastening members. However, the fastening members are not limited to this, and other fastening members such as bolts and nuts may be used.

また、中空の部材または円筒状の部材からなるリベット(締結部材)を用いることによって、軸方向に貫通する穴を設けても、磁束密度の低い部分を貫通するリベット(締結部材)が磁束の流れを阻害することがない。   Further, by using a rivet (fastening member) made of a hollow member or a cylindrical member, the rivet (fastening member) that penetrates a portion having a low magnetic flux density flows even if a hole that penetrates in the axial direction is provided. Will not be disturbed.
