Description
【０００１】[0001]
本考案は、サーボモータ等の回転電機の冷却装置に関するものである。 The present invention relates to a cooling device for a rotary electric machine such as a servo motor.
【０００２】[0002]
近年、たとえばサーボモータにおいては、高密度巻線技術の発達や永久磁石の 高性能化によって著しく小形、軽量化されてきた。 In recent years, for example, servo motors have been significantly reduced in size and weight due to the development of high-density winding technology and higher performance of permanent magnets.
【０００３】[0003]
ところが、従来のサーボモータをさらに小形化しようとすると、モータ自身の 温度上昇が限界値を越えてしまうという問題と、その高いモータの熱が例えば工 作機械などの装置へ伝達され装置に悪影響を及ぼすという問題があった。 そこで、本考案は、モータが良好に冷却される冷却装置を提供することを目的 とするものである。 However, if the conventional servo motor is further miniaturized, the problem that the temperature rise of the motor itself exceeds the limit value and the high heat of the motor is transmitted to the device such as the working machine and the device is adversely affected. There was a problem of exerting it. Then, this invention aims at providing the cooling device which cools a motor favorably.
【０００４】[0004]
上記問題を解決するため、本考案の回転電機の冷却装置は、固定子巻線をスロ ットに巻装し、かつ外周面に螺旋状の溝を形成した固定子鉄心と、前記溝に巻き つけた冷却用管と、前記固定子鉄心と冷却用管とをインサートモールドして形成 したモールド体とをそなえるようにしたものである。 In order to solve the above problems, a cooling device for a rotating electric machine according to the present invention comprises a stator core having a stator winding wound around a slot and a spiral groove formed on the outer peripheral surface thereof, and the stator core wound around the groove. It is provided with the attached cooling pipe and a molded body formed by insert molding the stator core and the cooling pipe.
【０００５】[0005]
上記手段により、固定子鉄心と冷却用管とが直接接触し、しかも接触面積が広 いので、固定子鉄心の熱が効率よく冷却用管に伝達され、モータの冷却が良好に 行われる。 By the above means, the stator core and the cooling pipe are in direct contact with each other and the contact area is wide, so that the heat of the stator core is efficiently transmitted to the cooling pipe, and the motor is cooled well.
【０００６】[0006]
以下、本考案の実施例を図に基づいて説明する。 図１は、本考案の実施例を示す側断面図である。 図においては、鉄心を積層して構成された固定子鉄心で、図示しないスロット に固定子巻線２を巻装している。３はこの固定子鉄心１の外周面に形成した螺旋 状の溝で、図では円弧状に形成している。４は前記螺旋状の溝３に巻きつけた冷 却用管で、図では前記溝３の形状に対応するように円管状に形成している。５は 前記固定子鉄心１と冷却用管４とをインサートモールドして形成したモールド体 で、フレームの役割をしている。 このような構成において、モータを冷却する際は、前記冷却用管４に水などの 冷媒を通して、固定子鉄心１の熱を吸収し、モータ外部に排出するわけであるが 、固定子鉄心１と冷却用管４とが直接密着接触し、しかも接触面積が広いので、 モータの冷却は良好に行われる。 なお、前記溝３は円弧状でなく角状としてもよく、この場合は冷却用管も溝３ の形状に合わせて角状にする。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing an embodiment of the present invention. In the figure, a stator core 2 is formed by stacking iron cores, and the stator winding 2 is wound in a slot (not shown). Reference numeral 3 denotes a spiral groove formed on the outer peripheral surface of the stator core 1, which is formed in an arc shape in the figure. Reference numeral 4 denotes a cooling pipe wound around the spiral groove 3, and is formed in a circular tube shape corresponding to the shape of the groove 3 in the figure. Reference numeral 5 denotes a mold body formed by insert-molding the stator core 1 and the cooling pipe 4, which serves as a frame. In such a configuration, when cooling the motor, the heat of the stator core 1 is absorbed by passing a coolant such as water through the cooling pipe 4 and discharged to the outside of the motor. The motor 4 is cooled well because the cooling pipe 4 is in direct contact and has a large contact area. The groove 3 may have a square shape instead of an arc shape. In this case, the cooling pipe is also made into a square shape in accordance with the shape of the groove 3.
【０００７】[0007]
以上述べたように、本考案によれば、サーボモータ等の回転電機の冷却を良好 に行うことができ、サーボーモータ等をさらに小形化することができる効果があ る。 As described above, according to the present invention, it is possible to satisfactorily cool the rotating electric machine such as the servo motor, and it is possible to further reduce the size of the servo motor.
