Abstract
Description
本発明は、電気機器に用いられる電動機全般に使用される回転子のアンバランス修正方法に関する。 The present invention relates to a method for correcting an unbalance of a rotor used for all electric motors used in electrical equipment.
従来、電気機器に用いられる電動機に使用される回転子２１の重量アンバランス修正方法としては、バランス測定機器により求められた、回転子２１の重量アンバランスの大きい部分に対し、図２に示すように、回転子鉄心の外周表面２２に切削などの工法により切削部分２３を設け、重量を減じて修正する方法や、回転子２１のアンバランスの小さい部分に対し、粘土のような材質を回転子２１の表面付近に貼り付けることにより、重量を増して修正する方法が一般的であった。 Conventionally, as a method for correcting the weight unbalance of the rotor 21 used in the electric motor used in the electric device, a portion where the weight unbalance of the rotor 21 obtained by the balance measuring device is large is shown in FIG. In addition, a cutting portion 23 is provided on the outer peripheral surface 22 of the rotor core by a method such as cutting, and the weight is reduced and the rotor 21 is made of a material such as clay for the small unbalanced portion of the rotor 21. A method of correcting by increasing the weight by pasting near the surface of 21 was common.
かかる先行技術は、文献公知発明に係るものでないため、記載すべき先行技術文献情報はない。 Since such prior art is not related to the literature known invention, there is no prior art document information to be described.
しかしながら、上記のような従来の回転子の重量アンバランス修正方法において、回転子鉄心の外周部分の切削工法の場合、回転子外周と固定子内周間の寸法、いわゆるギャップ寸法が、部分的に増加することにより、磁気的な振動が発生したり、平均的なギャップ寸法の増加に伴い、電動機の消費電力が増加してしまうといった課題があった。 However, in the conventional rotor weight imbalance correction method as described above, in the case of the cutting method of the outer peripheral portion of the rotor core, the dimension between the outer periphery of the rotor and the inner periphery of the stator, the so-called gap dimension, is partially Increasing the power causes problems such as generation of magnetic vibration and increase in power consumption of the motor as the average gap size increases.
また、粘土のような材質を回転子の表面付近に貼り付ける工法の場合でも、電動機が高回転で運転される際に、遠心力で前記材質が剥がれてしまうことにより、回転子のアンバランス修正が崩れ、電動機の機械的振動が大きくなってしまうといった課題があった。 In addition, even in the case of a method of attaching a material such as clay near the surface of the rotor, when the electric motor is operated at a high speed, the material is peeled off by centrifugal force, thereby correcting the rotor imbalance. There has been a problem that the mechanical vibration of the electric motor becomes large due to collapse.
上記課題を解決するために本発明は、電動機に用いられる回転子において、長さ及び比重の異なる部材を回転子鉄心のオープンスロット部分に配設することで、前記回転子の重量アンバランスを修正することを特徴とする回転子加工方法である。 In order to solve the above-mentioned problems, the present invention corrects the weight imbalance of the rotor by disposing members having different lengths and specific gravity in the open slot portion of the rotor core in the rotor used in the electric motor. And a rotor machining method.
上記工法で回転子の重量アンバランスを修正することにより、回転子鉄心の外周を部分的に切削したりしないので、固定子と回転子のギャップ寸法が部分的にも平均的にも増加したりすることはない。 By correcting the weight imbalance of the rotor by the above method, the outer circumference of the rotor core is not partially cut, so the gap dimension between the stator and the rotor increases both partially and on average. Never do.
また、アンバランス修正用の部材を回転子鉄心のオープンスロット部分の隙間に挿入し固定するので、高速回転で外れたりすることはない。 Further, since the member for correcting imbalance is inserted and fixed in the gap in the open slot portion of the rotor core, it does not come off at high speed.
上記本発明の回転子アンバランス修正方法は、部材を回転子鉄心のオープンスロット部分に配設するだけの簡単な構成で、容易に回転子のアンバランスを修正できる。 The rotor imbalance correction method of the present invention can easily correct the rotor unbalance with a simple configuration in which the member is simply disposed in the open slot portion of the rotor core.
そして、固定子と回転子のギャップ寸法を全周均一の状態に保てるので、回転中に磁気的なアンバランスによる振動も発生することがなく、また、平均的なギャップ寸法も増加しないので、電動機効率の低下も招くことがなく、低振動、低騒音、高効率な電動機を提供できる。 And since the gap dimension between the stator and the rotor can be kept uniform over the entire circumference, vibration due to magnetic imbalance does not occur during rotation, and the average gap dimension does not increase. There is no reduction in efficiency, and a low-vibration, low-noise, high-efficiency electric motor can be provided.
さらに、アンバランス修正用部材は回転子鉄心のオープンスロット部分にしっかりと固定されており、高速回転においても決して外れることがないので、回転子の重量バランスが崩れず、回転中の機械的振動が増加することがなく、低振動、低騒音でかつ安全な電動機を提供できる。 Furthermore, the unbalance correcting member is firmly fixed to the open slot portion of the rotor core, and never loses even during high-speed rotation. Therefore, the weight balance of the rotor is not lost, and mechanical vibration during rotation does not occur. It is possible to provide a low-vibration, low-noise and safe motor without increasing.
本発明の実施の形態は、電動機に用いられる回転子において、長さ及び比重の異なる部材を回転子鉄心のオープンスロット部分に配設することで、前記回転子の重量アンバランスを修正することを特徴とする回転子加工方法であり、簡単な構成で容易に回転子の重量アンバランスを修正でき、回転子の重量アンバランスを修正しても、固定子と回転子のギャップ寸法が部分的にも平均的にも増加したりすることがなく、かつ、高速回転でもアンバランス修正用部材が外れたりすることがない。 According to an embodiment of the present invention, in a rotor used in an electric motor, members having different lengths and specific gravity are disposed in an open slot portion of the rotor core, thereby correcting the weight imbalance of the rotor. The rotor processing method is characterized by a simple configuration that can easily correct the rotor weight imbalance, and even if the rotor weight imbalance is corrected, the gap dimension between the stator and the rotor is partially And the average is not increased, and the unbalance correcting member does not come off even at high speed rotation.
また、上記工法において、アンバランス修正用部材として非磁性体を用いることで、磁気的なアンバランスも抑えることができる。 Further, in the above construction method, a magnetic imbalance can be suppressed by using a non-magnetic material as the unbalance correcting member.
また、上記工法において、アンバランス修正用部材として黄銅を用いることで、黄銅は安価で加工性が良好なので、安価で容易に回転子の重量アンバランスを修正することができる。 Moreover, in the said construction method, since brass is cheap and favorable workability by using brass as a member for unbalance correction, the weight imbalance of a rotor can be corrected easily cheaply.
また、上記工法において、アンバランス修正用部材として樹脂を用いることで、樹脂はより加工性に優れ形状自由度が大きいので、より容易に回転子の重量アンバランスを修正することができる。 Moreover, in the said construction method, since resin is excellent in workability and a shape freedom degree is large by using resin as a member for unbalance correction, the weight imbalance of a rotor can be corrected more easily.
さらに、上記工法により回転子の重量アンバランスを修正した電動機用回転子を用いることで、低振動、低騒音、高効率でかつ安全な電動機を提供することができる。 Furthermore, by using a rotor for an electric motor whose weight imbalance of the rotor is corrected by the above method, a low-vibration, low-noise, high-efficiency and safe electric motor can be provided.
以下、本発明の実施例について図面を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
（実施例１）
図１は電動機の回転子１を示す斜視図であり、回転子１の重量分布のアンバランスをバランス測定機器により求め、その重量アンバランスを修正するために、回転子鉄心２のオープンスロット部分に適当な形状に加工した黄銅の小片３を挿入して固定する。
(Example 1)
FIG. 1 is a perspective view showing a rotor 1 of an electric motor. An unbalance of a weight distribution of the rotor 1 is obtained by a balance measuring device, and an open slot portion of the rotor core 2 is corrected to correct the weight unbalance. A small piece 3 of brass processed into an appropriate shape is inserted and fixed.
上記構成をとることで、簡単な構成で容易に回転子の重量アンバランスを修正でき、回転時の機械的な回転ムラが低減されるだけでなく、回転子鉄心２のティース表面を切削したりしないので、固定子と回転子のギャップ寸法を全周均一の状態に保て、磁気的なアンバランスによる振動が発生しない。また、平均的なギャップ寸法も増加しないので、電動機効率の低下も招くことがなく、低振動、低騒音、高効率な電動機を提供できる。 By adopting the above configuration, the weight unbalance of the rotor can be easily corrected with a simple configuration, and not only mechanical rotation unevenness during rotation is reduced, but also the tooth surface of the rotor core 2 is cut. Therefore, the gap between the stator and the rotor is kept uniform throughout the circumference, and vibration due to magnetic imbalance does not occur. In addition, since the average gap size does not increase, the motor efficiency is not lowered, and a low-vibration, low-noise, high-efficiency motor can be provided.
さらに、アンバランス修正用部材である黄銅の小片３は、回転子鉄心２のオープンスロット部分に挿入され、しっかりと固定されており、高速回転においても決して外れることがないので、回転子の重量バランスが崩れず、回転中の機械的振動が増加することがなく、低振動、低騒音でかつ安全な電動機を提供できる。 Further, the brass piece 3 which is an unbalance correcting member is inserted into the open slot portion of the rotor core 2 and is firmly fixed, so that it never comes off even at high speed rotation. Therefore, the mechanical vibration during rotation does not increase, and a low-vibration, low-noise and safe motor can be provided.
なお、アンバランス修正用部材として、樹脂の小片を用いてもよい。その場合、形状自由度が大きくなるので、アンバランスを修正するための最適な形状をより容易に作成でき、回転子のアンバランス修正をより容易に実施できる。 A resin piece may be used as the unbalance correcting member. In that case, since the degree of freedom in shape increases, an optimal shape for correcting the unbalance can be created more easily, and the rotor unbalance can be corrected more easily.
本発明の電動機用回転子のアンバランス修正方法は、簡単な構成で容易に回転子のアンバランスを修正でき、低振動、低騒音、高効率な電動機を提供でき、掃除機用ブロワモータ等の整流子モータ等への利用が可能である。 The method for correcting an unbalance of a rotor for an electric motor according to the present invention can easily correct the unbalance of the rotor with a simple configuration, can provide a low-vibration, low-noise, high-efficiency electric motor, and can be used for a rectifier such as a blower motor for a vacuum cleaner. It can be used for a child motor or the like.
