    摘要： It is possible to control a welding in a high speed and a high precision large electric current, and consumption electric power is also reduced. In the welding transformer, a loop magnetic core 25, a wound primary coil 12, plural positive side coils 14 and plural negative side coils 16 that are alternately sandwiched between respective gaps 12a of the primary coil 12, are comprised. A coil is fixed on the other surface of a contact base member 62. On the other surface of the contact base member 62, a first connection polar board 44 is electrically connected to a positive side electric conductor 30 through the first connection polar board 44. A negative side coil 16 is electrically connected to a negative side electric conductor 32. The connecting part of the positive side coil 14 and the negative side coil 16 is electrically connected to the third connection polar board 48. By sandwiching a thin insulation layer 31, a positive side electric conductor 30, a rectifying device 18 and a first polar board 34 are arranged on one side; A negative side electric conductor 32, a rectifying device 20 and a second polar board 36 are arranged on the other side; and the first polar board 34 and the second polar board 36 are electrically connected to a third polar board 38. It is possible to use by combining plural units and by connecting an output side in parallel in a small size and a large capacity.

    摘要： A method of manufacturing a laminated rotor core, includes a first process of placing segment dummy plates between an iron core and a die, each of each segment dummy plates covering one or more of plural magnet insertion portions and including a resin injection hole communicating to the one or more of the magnet insertion portions; a second process of injecting a resin from resin reservoir parts formed in any one of an upper die and a lower die holding the iron core through the resin injection hole of each segment dummy plate to the corresponding one or more of the magnet insertion portions; and a third process of detaching the segment dummy plates together with excess resin after the resin injected to the one or more of the magnet insertion portions is cured.
