    • An alternator of high quality and high performance includes a rotor, a stator core arranged so as to surround the rotor and having a plurality of axially extending slots arranged at a predetermined circumferential pitch, and a stator having a stator winding fitted into the slots. The stator core includes element iron cores of a hexahedral shape which are deformed to curve, with their adjacent end faces being abutted and bonded to each other, each of the element iron cores being composed of thin steel plates laminated and integrated with one another, with concave and convex portions formed on the thin steel plates being fitting with each other. The concave and convex portions are formed on a borderline between a compressive region of the stator core at an inner diameter side thereof and a tensile region of the stator core at an outer diameter side thereof.

    • An engine generator is provided having an improved cooling effect realized by cooling air while ensuring a compact arrangement of components in a housing. The engine generator includes an engine 2, a generator 3, an inverter 4, a control device, a fuel tank 7, an air cleaner 16, a muffler 18, a radiator 6, and a housing 5 accommodating the foregoing components. The engine generator includes cooling air inlets 12 and 11 and a cooling air outlet 14 on sides of the housing 5 with a cooling air passage disposed between the inlets and outlet. The generator 3, the inverter 4, and the air cleaner 16 are disposed further upstream than the engine 2 along a cooling air passage. The fuel tank 7, the radiator 6, and the muffler 18 are disposed further downstream than the engine 2 along the cooling air passage. Ambient air is incorporated as cooling air into the housing 5 through the cooling air inlets 12 and 11, allowed to flow from an upstream toward a downstream of the cooling air passage, and discharged to outside the housing 5 through the cooling air outlet 14.
    • 提供一种发动机发电机,其具有通过冷却空气实现的改进的冷却效果,同时确保部件在壳体中的紧密布置。 发动机发电机包括发动机2,发电机3,逆变器4,控制装置,燃料箱7,空气滤清器16,消音器18,散热器6和容纳上述部件的壳体5。 发动机发电机包括冷却空气入口12和11以及在壳体5的侧面上的冷却空气出口14,其中冷却空气通道设置在入口和出口之间。 发电机3,逆变器4和空气滤清器16沿着冷却风道设置在发动机2的上游。 燃料箱7,散热器6和消音器18沿着冷却空气通道设置在发动机2的下游。 环境空气通过冷却空气入口12和11作为冷却空气并入到壳体5中,允许从冷却空气通道的上游流向下游,并通过冷却空气出口14排出到壳体5的外部。
