Description
【0001】[0001]
本考案は、モータ回転子磁性材料の固定構造に関し、特に、回転子を構成する 珪素鋼板における収容部は複数の板ばねを有し、前記各板ばねの相対する内縁は 磁性材料の寸法よりやや小さいため、発生する弾性力により磁性材料がしっかり と固定されるモータ回転子磁性材料の固定構造に関する。 The present invention relates to a structure for fixing a magnetic material of a motor rotor, and in particular, an accommodating portion in a silicon steel plate constituting the rotor has a plurality of leaf springs, and an inner edge of each of the leaf springs is slightly larger than a size of the magnetic material. The present invention relates to a structure for fixing a magnetic material of a motor rotor in which a magnetic material is firmly fixed by an elastic force generated because the magnetic material is small.
【0002】[0002]
モータの回転子は、複数の珪素鋼板の積み重ねにより構成され、珪素鋼板の周 縁は同じ距離で複数の凹溝を有する。各凹溝の寸法は磁性材料よりやや大きく設 計され、磁性材料は、粘着剤が塗布された後、各凹溝に置き入れられ、粘着によ り結合される。 The rotor of the motor is configured by stacking a plurality of silicon steel plates, and the periphery of the silicon steel plates has a plurality of concave grooves at the same distance. The dimensions of each groove are designed to be slightly larger than the magnetic material, and the magnetic material is placed in each groove after the adhesive is applied, and bonded by adhesion.
【0003】 しかしながら、粘着方式で磁性材料が結合される方法は、モータが一定時間使 用されると、磁性材料が高速回転の状態で脱落することがある。 粘着された磁性材料が脱落し易い問題を解決するため、磁性材料は埋め込み方 式で回転子と結合される。図4および図5に示すように、他の従来のモータの珪 素鋼板8は、中心部位に芯軸を貫通するために提供される固定孔81を有する。 前記珪素鋼板8の外周部位には、磁性材料9を置き入れるために提供され、同じ 距離で配置されている貫通孔82を有する。前記貫通孔82は、磁性材料9と締 りばめの形態で結合されるため、貫通孔82の中に埋められ、設置されるとき、 しっかりと固定される。However, in the method in which the magnetic material is bonded by the adhesive method, when the motor is used for a certain period of time, the magnetic material may fall off at a high speed. In order to solve the problem that the adhered magnetic material is easy to fall off, the magnetic material is combined with the rotor in an embedded manner. As shown in FIGS. 4 and 5, a silicon steel plate 8 of another conventional motor has a fixing hole 81 provided at a central portion to penetrate a core shaft. The outer peripheral portion of the silicon steel plate 8 has through holes 82 provided for placing the magnetic material 9 and arranged at the same distance. Since the through-hole 82 is coupled to the magnetic material 9 in the form of an interference fit, it is buried in the through-hole 82 and firmly fixed when installed.
【0004】 磁性材料9がしっかりと貫通孔82の中で固定されるため、貫通孔82の寸法 は磁性材料9の寸法より小さくに設計されているが、磁性材料9は割れ易い材質 で作製されているため、磁性材料9が無理に貫通孔82に押し入れられると、磁 性材料9は割れ、不良品を発生することがある。Since the magnetic material 9 is firmly fixed in the through hole 82, the size of the through hole 82 is designed to be smaller than the size of the magnetic material 9, but the magnetic material 9 is made of a material that is easily broken. Therefore, if the magnetic material 9 is forcibly pushed into the through hole 82, the magnetic material 9 may be cracked and defective products may be generated.
【0005】 また、磁性材料9は、埋められ、設置された後、貫通孔82の周囲と密着され るため、回転子の回転中に発生する熱を発散し難く、温度上昇による磁性材料9 の効率低下の問題を発生する。貫通孔82と珪素鋼板8の外周縁とに一定距離が ないとき、磁性材料9を固定するための強度は不十分である。この一定距離は磁 性材料9と回転子の外周にある固定子91との間の距離を増加し、磁性材料9と 固定子との間の隙間Hを増大し、モータのトルク低下の問題を起こすため、前述 した磁性材料の固定構造は改善される必要がある。After the magnetic material 9 is buried and installed, the magnetic material 9 is in close contact with the periphery of the through hole 82, so it is difficult to radiate heat generated during rotation of the rotor, and the magnetic material 9 is heated due to a rise in temperature. The problem of reduced efficiency occurs. When there is no fixed distance between the through hole 82 and the outer peripheral edge of the silicon steel plate 8, the strength for fixing the magnetic material 9 is insufficient. This constant distance increases the distance between the magnetic material 9 and the stator 91 on the outer periphery of the rotor, increases the gap H between the magnetic material 9 and the stator, and reduces the problem of motor torque reduction. Therefore, the above-mentioned structure for fixing the magnetic material needs to be improved.

本考案は、各珪素鋼板の周縁における収容部に複数の板ばねが形成され、磁性 材料が前記収容部に設けられ、各板ばねは若干の弾性変形し、各板ばねの弾性力 により均等に磁性材料は挟持され、磁性材料を安定し固定するモータ回転子磁性 材料の固定構造を提供することを主要な目的とする。 According to the present invention, a plurality of leaf springs are formed in the accommodating portion at the peripheral edge of each silicon steel plate, a magnetic material is provided in the accommodating portion, and the respective leaf springs are slightly elastically deformed, and are uniformly distributed by the elastic force of the respective leaf springs. A main object of the present invention is to provide a motor rotor magnetic material fixing structure in which a magnetic material is sandwiched and which stably fixes the magnetic material.
【0007】 本考案は、磁性材料が収容部に置き入れられるとき、各板ばねは変形し、収容 部の寸法が増大するため、磁性材料は置き入れ易く、磁性材料を損傷しないモー タ回転子磁性材料の固定構造を提供することを次の目的とする。 本考案は、各収容部が珪素鋼板の外周縁から内側に凹んでいるため、磁性材料 は、収容部に設けられた後、固定子にさらに接近し、磁性材料と固定子との間の 隙間を減少することができ、モータの回転トルクを向上することができるモータ 回転子磁性材料の固定構造を提供することをもう一つの目的とする。According to the present invention, when the magnetic material is placed in the housing, the leaf springs are deformed, and the size of the housing is increased, so that the magnetic material is easily placed and the magnetic material is not damaged. It is another object of the present invention to provide a fixing structure for a magnetic material. According to the present invention, since each housing is recessed inward from the outer peripheral edge of the silicon steel sheet, the magnetic material is provided in the housing and then further approaches the stator, and the gap between the magnetic material and the stator is reduced. It is another object of the present invention to provide a structure for fixing a magnetic material of a motor rotor, which can reduce the motor torque and improve the rotational torque of the motor.
【0008】 磁性材料は、収容部に置き入れられるとき、窪み部の割れにより形成された複 数の板ばねで緊迫し固定され、磁性材料の周囲は窪み部で形成されるエアを流通 する経路を有するため、モータの運転中の磁性材料の熱発散効率は向上する。ま た、磁性材料の外部は回転子と固定子とで形成される隙間に露出されているため 、埋め込み式のものより熱発散し易く、磁性材料の熱により発生する悪影響を回 避できるモータ回転子磁性材料の固定構造を提供することをもう一つの目的とす る。When the magnetic material is placed in the storage portion, the magnetic material is tightly fixed by a plurality of leaf springs formed by cracks in the recess, and the periphery of the magnetic material flows through the air formed by the recess. Therefore, the heat dissipation efficiency of the magnetic material during operation of the motor is improved. In addition, since the outside of the magnetic material is exposed to the gap formed by the rotor and the stator, heat is more easily dissipated than the embedded type, and the motor rotation that can avoid the adverse effects caused by the heat of the magnetic material can be avoided. It is another object to provide a fixing structure for a magnetic material.

以下、本考案の実施の形態を図面に基づいて説明する。 図1から図3に示すように、本考案の一実施例によるモータ回転子は、複数の 珪素鋼板1が積み重ねられ、構成されている。珪素鋼板1の外周縁には同じ距離 で内側に凹み、磁性材料2を収容する複数の収容部11が設けられている。収容 部11と珪素鋼板1との間には側面111および側面112と、底面113と、 前記底面と相対する開口114とが別々に形成されている。前記開口114は前 記収容部11の内部の幅より小さく形成され、前記側面111および前記側面1 12は外側から内側に徐々に広がる斜面である。側面111および側面112と 底面113との連接部はそれぞれ窪み部12を有する。前記収容部11における 側面111、側面112及び底面113はそれぞれ窪み部12に割り込まれ、三 板ばね13が形成されている。前記三板ばね13と磁性材料には締りばめ状態が 形成され、前記珪素鋼板1の中心部位は芯軸を貫通するための貫通孔14を有す る。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 to FIG. 3, the motor rotor according to one embodiment of the present invention is configured by stacking a plurality of silicon steel plates 1. A plurality of accommodating portions 11 accommodating the magnetic material 2 are provided on the outer peripheral edge of the silicon steel sheet 1 at the same distance and inward. Side surfaces 111 and 112, a bottom surface 113, and an opening 114 facing the bottom surface are separately formed between the housing portion 11 and the silicon steel plate 1. The opening 114 is formed to be smaller than the width of the inside of the accommodating portion 11, and the side surface 111 and the side surface 112 are slopes gradually expanding from the outside to the inside. The side surface 111 and the connecting portion between the side surface 112 and the bottom surface 113 each have a concave portion 12. The side surface 111, the side surface 112, and the bottom surface 113 of the housing portion 11 are each cut into the recessed portion 12 to form a triple leaf spring 13. An interference fit is formed between the three-plate spring 13 and the magnetic material, and a central portion of the silicon steel plate 1 has a through hole 14 for penetrating a core shaft.
【0011】 前述した構造に磁性材料2が置き入れられるとき、各板ばね13が磁性材料2 に押され、変形する。したがって、磁性材料2が置き入れられるとき、板ばね1 3の変形により収容部11の寸法は増大される。このため、磁性材料2が締りば めにされるとき、磁性材料2は損傷されない。磁性材料2が配置された後、三板 ばね13の弾性変形で発生する弾性力により磁性材料2はしっかりと挟持され、 磁性材料2は安定し固定される。開口114は収容部11の内部の幅よりやや狭 いため、前記側面111および前記側面112は外側から内側に徐々に広がる斜 面である。したがって、三板ばね13に挟持されている磁性材料2はモータの高 速回転で脱落しない。When the magnetic material 2 is placed in the above-described structure, each leaf spring 13 is pressed by the magnetic material 2 and deforms. Therefore, when the magnetic material 2 is placed, the size of the housing portion 11 is increased by the deformation of the leaf spring 13. Therefore, when the magnetic material 2 is tightened, the magnetic material 2 is not damaged. After the magnetic material 2 is arranged, the magnetic material 2 is firmly held by the elastic force generated by the elastic deformation of the three-plate spring 13, and the magnetic material 2 is stably fixed. Since the opening 114 is slightly narrower than the width of the inside of the accommodating portion 11, the side surface 111 and the side surface 112 are slopes gradually expanding from the outside to the inside. Therefore, the magnetic material 2 held between the three leaf springs 13 does not fall off due to the high-speed rotation of the motor.
【0012】 収容部11は一部が三板ばね13で磁性材料2と接触し、窪み部12はエアが 流通できる経路である。回転子の回転中に磁性材料2で発生する熱は流通してい るエアで排出されるため、磁性材料2の温度上昇により発生する磁性エネルギー の低下の問題は回避できる。また、各収容部11は珪素鋼板1の外周縁から内側 に凹んでいるため、磁性材料2は、収容部11に設けられた後、固定子3にさら に接近する。したがって、磁性材料2と固定子3との間の隙間hを減少すること ができ、図3に示すように、モータの回転トルク及び効率を向上することができ る。The housing 11 is partially in contact with the magnetic material 2 by a three-plate spring 13, and the recess 12 is a path through which air can flow. Since the heat generated in the magnetic material 2 during the rotation of the rotor is exhausted by the flowing air, the problem of a decrease in the magnetic energy generated by the temperature rise of the magnetic material 2 can be avoided. Further, since each of the accommodating portions 11 is depressed inward from the outer peripheral edge of the silicon steel sheet 1, the magnetic material 2 is provided in the accommodating portion 11 and then approaches the stator 3 further. Therefore, the gap h between the magnetic material 2 and the stator 3 can be reduced, and as shown in FIG. 3, the rotational torque and efficiency of the motor can be improved.
【0013】 本考案は下記の効果がある。 (イ)収容部11における複数の板ばね13は、弾性変形で発生する弾性力に より磁性材料2をしっかりと挟持するため、磁性材料2を安定に固定することが できる。The present invention has the following effects. (A) The plurality of leaf springs 13 in the housing 11 firmly hold the magnetic material 2 by the elastic force generated by the elastic deformation, so that the magnetic material 2 can be fixed stably.
【0014】 (ロ)磁性材料2が収容部11に置き入れられるとき、各板ばね13は若干の 変形を生じるため、磁性材料2は入れ易く、磁性材料2は損傷されない。 (ハ)磁性材料2が収容部11に設けられた後、磁性材料2は固定子3にさら に接近するため、磁性材料2と固定子3との間の隙間hを減少することができ、 モータの回転トルク及び効率を向上することができる。(B) When the magnetic material 2 is placed in the housing portion 11, each leaf spring 13 slightly deforms, so that the magnetic material 2 is easy to enter and the magnetic material 2 is not damaged. (C) After the magnetic material 2 is provided in the accommodating section 11, the magnetic material 2 comes closer to the stator 3, so that the gap h between the magnetic material 2 and the stator 3 can be reduced. The rotational torque and efficiency of the motor can be improved.
【0015】 (ニ)磁性材料2が収容部11に置き入れられるとき、窪み部12はエアを流 通する経路になり、開口114における磁性材料2は直接回転子と固定子とで形 成される隙間hに露出されるため、モータの回転中の熱発散効率を向上すること ができる。(D) When the magnetic material 2 is placed in the accommodating portion 11, the recessed portion 12 becomes a path through which air flows, and the magnetic material 2 in the opening 114 is directly formed by the rotor and the stator. As a result, the heat dissipation efficiency during rotation of the motor can be improved.
