Embodiment 1
[0104] Coated and baked acrylic resin (composition: 85% acrylic resin, 15% epoxy resin, softening temperature 70°C) with a thickness of 0.5mm electric iron plate (electrical steel sheet) with a heat-adhesive insulating film Punched into a ring shape with an outer diameter of 100 mm and an inner diameter of 50 mm, and stacked 100 workpieces to form the device, put it into the device of the present invention in the form shown in Figure 1A, and excite and pressurize under the various conditions shown in Table 1. A laminated core manufacturing test in which electric iron plates in a workpiece are heated and bonded to each other was conducted, and the heating time and bonding state were studied.
[0105]In addition, as the insulating plate 6, a Rosner plate (manufactured by Nikko Kasei Co., Ltd.; thermal conductivity: 0.24 W / m·K) with a diameter of 110 mm and a plate thickness of 5 mm was used. In addition, as the guide 8, a plate as shown in FIGS. 5A to 5C was used. The shape of t...
Embodiment 2
[0118] The same workpiece as in Example 1 is packed into the device of the present invention in the form shown in Figure 1B, and is excited and pressurized under various conditions shown in Table 2 to heat and bond the electric iron plates in the workpiece to each other. In the manufacturing test of the laminated core of the junction, the bonding state was judged by the same method as in Example 1 while examining the heating time and the bonding state. In addition, the insulation board 6 and the guide 8 used the same thing as Example 1 except the example mentioned especially. In addition, as the core core, electromagnetic steel sheets with a thickness of 0.5mm are laminated into the shape shown in Figure 4C (the material with a wide width is 33mm×100mm, and the number of layers is 40; the material with a width of 20mm×100mm, the number of layers is 13 respectively. ) fixed iron core, inserted into the central hole of the aforementioned workpiece along the direction shown in Fi...
