面が少くなく放熱が悪くなつて回転電機の温度が
高くなるという欠点があつた。 Figure 1 is a partial cross-sectional view of a conventional fully enclosed external fan-shaped rotating electrical machine.The stator core 1 is punched out using a press into a circular, 1/4 or 1/6 fan shape, and then stacked to form a cylindrical shape. Clamping grooves 2 are provided at several locations around the circumference as the stator core.
A clamping band iron 3 is placed in the clamping groove 2.
A stator core 1 is formed by installing press plates (not shown) at both ends of the stator and welding the clamping band iron 3 to the press plates. The stator core 1 thus formed is press-fitted into the frame 4 to form a stator of a rotating electric machine. However, the positions of the internal air circulation duct 5 provided in the frame 5 and the clamping groove 2 of the stator core 1 are generally unrelated, and a gap is created between the clamping band 3 and the frame 4. There was a drawback that the contact surface between the iron core 1 and the frame 4 was small, resulting in poor heat dissipation and an increase in the temperature of the rotating electric machine.
本考案の目的は回転電機の固定子とフレームの
嵌合部の相対位置を改善して放熱効果を向上させ
た回転電機を提供することにある。 An object of the present invention is to provide a rotating electrical machine that improves the heat dissipation effect by improving the relative position of the fitting portion between the stator and frame of the rotating electrical machine.

レーム４に伝達放熱される。 An embodiment of the present invention will be described below with reference to FIG. Note that the same parts as in FIG. 1 are given the same reference numerals and detailed explanations are omitted. The positions of the internal air circulation air passage 5 provided in the frame 4 and the clamp groove 2 of the stator core 1 are made to coincide with each other. With this configuration, the stator core 1 and the frame 4 are in contact with each other without gaps at positions other than the internal air circulation air passage 5, so that heat can be effectively transferred from the stator core 1 to the frame 4. . The portion of the clamping iron band 3 that has reached the inside air circulation air passage 5 is effectively cooled by the inside air flowing therethrough, so that the heat dissipation of the stator core 1 is further improved. The heat transferred to the inside air is transferred to the frame 4 and radiated from the inside air.
