Abstract
Description
本発明は、車両用の台車内に据え付けられている主電動機の固定子の通風構造の構成に関するものである。 The present invention relates to a structure of a ventilation structure for a stator of a main motor installed in a vehicle carriage.
主電動機の運転を続けると主電動機の内部が発熱するため、冷却経路が必要となるが、全閉内扇方式の場合は、機内の冷却風の温度低減のために、固定子枠の外側に冷却器を設ける場合が多い。 As the main motor continues to operate, the inside of the main motor generates heat, so a cooling path is required.However, in the case of a fully enclosed internal fan system, it is located outside the stator frame to reduce the temperature of the cooling air inside the machine. A cooler is often provided.
前記の場合、冷却器を固定子枠の外側に設けるため、主電動機全体が大きくなったり、固定子枠を直接冷却するための冷却フィンを固定子枠に設ける必要があった。また、固定子鉄心と冷却器が離れて設置されているため、固定子鉄心に蓄積された熱を効率よく機外へ放散することに対して問題があった。 In this case, since the cooler is provided outside the stator frame, the entire main motor has to be large, or cooling fins for directly cooling the stator frame have to be provided in the stator frame. Further, since the stator core and the cooler are installed apart from each other, there is a problem in efficiently dissipating the heat accumulated in the stator core to the outside of the machine.
本発明は、冷却器の配置を変更することにより、固定子鉄心に蓄積された熱を効率よく機外へ放散させることができ、小型化を図った主電動機を提供することが目的である。 SUMMARY OF THE INVENTION An object of the present invention is to provide a main motor that is capable of efficiently dissipating heat accumulated in a stator core to the outside of the machine by changing the arrangement of the cooler, and is downsized.
請求項1の発明は、固定子鉄心の外径側に軸方向に溝を設け,前記溝と対向する固定子枠の部分に開口部を設け,前記固定子枠の開口部に機外方向に向けられたフィンを有する冷却器を設け,前記冷却器は前記固定子鉄心と前記固定子枠とに挟まれていることを特徴としている。 According to the first aspect of the present invention, a groove is provided in the axial direction on the outer diameter side of the stator core, an opening is provided in a portion of the stator frame facing the groove, and the opening of the stator frame extends outward from the machine. A cooler having directed fins is provided, the cooler being sandwiched between the stator core and the stator frame.
本発明の通風構造は、主電動機全体を小型化し、固定子鉄心に蓄積された熱を効率よく機外へ放散させることができる利点がある。 The ventilation structure of the present invention has an advantage that the entire main motor can be reduced in size, and heat accumulated in the stator core can be efficiently dissipated outside the machine.
図1、図2、図3にしたがって実施例等を説明する。 Examples and the like will be described with reference to FIGS. 1, 2, and 3.
図1は、本発明の実施例を示す断面図であって、1は固定子枠、2は固定子鉄心、3は冷却器、4は通風穴、5は固定子鉄心抑え、6はファンである。 FIG. 1 is a cross-sectional view showing an embodiment of the present invention, wherein 1 is a stator frame, 2 is a stator core, 3 is a cooler, 4 is a vent hole, 5 is a stator core restraint, and 6 is a fan. is there.
図2は、従来の一例を示す断面図であって、11は固定子枠、12は固定子鉄心、13は冷却器、14は通風穴、15は固定子鉄心抑え、16はファン、17は冷却器の入気口、18は冷却器の排気口である。 FIG. 2 is a cross-sectional view showing an example of the prior art, in which 11 is a stator frame, 12 is a stator core, 13 is a cooler, 14 is a vent hole, 15 is a stator core restraint, 16 is a fan, and 17 is An inlet of the cooler and 18 is an exhaust of the cooler.
図3は、本発明の実施例を示す断面図であって、符号は図1と同様である。冷却器3の一部分は固定子枠1と固定子鉄心2に挟まれている。 FIG. 3 is a cross-sectional view showing an embodiment of the present invention, and the reference numerals are the same as those in FIG. A part of the cooler 3 is sandwiched between the stator frame 1 and the stator core 2.
冷却器3と固定子鉄心2に設けられた溝により、通風穴4が構成されている。通風穴4は固定子鉄心2の任意の位置に1箇所または複数箇所設けることができる。通風穴4は固定子鉄心抑え5を貫通している。 A ventilation hole 4 is configured by a groove provided in the cooler 3 and the stator core 2. One or a plurality of ventilation holes 4 can be provided at any position of the stator core 2. The ventilation hole 4 passes through the stator iron core restraint 5.
図3の冷却器3の通風穴側において、断面上平面に記載してあるが、この面に通風方向に平行する凹凸を設け、通風時に固定子鉄心に蓄積された熱を効率よく冷却器を通じて冷却されることは言うまでもないことである。 On the side of the ventilation hole of the cooler 3 in FIG. 3, the plane is shown in a plane on the cross section, but this surface is provided with unevenness parallel to the ventilation direction, and the heat accumulated in the stator core during ventilation is efficiently passed through the cooler. It goes without saying that it is cooled.
固定子鉄心と冷却器を接触させ、固定子鉄心に蓄積された熱を効率よく機外へ放散させ、主電動機全体を小型化を実現するとともに、部品点数や嵌合部を削減させ、組立性の向上を図った主電動機を提供する。 The stator core and cooler are brought into contact with each other to efficiently dissipate the heat accumulated in the stator core to the outside of the machine. The main electric motor aiming at the improvement is provided.
