    • PROBLEM TO BE SOLVED: To achieve the comprehensively even cooling of a stator and the optimum control of magnetic field in a cable of stator windings, by improving a generator of a type that has a rotor supported in such a way as to be rotatable around axis of rotation and surrounded by a stator and that has stator windings, which, formed by insulated cables and arranged inside the laminated thin metal plates of the rotor, extend in the axial direction inside the metal plates and form a winding head on the end surface at the outside of the metal plates. SOLUTION: A stator having the laminated thin metal plates and the stator windings is put in a casing, which is sealed hermetically without containing the rotor. The inside chamber of the casing is filled with a coolant.
    • 要解决的问题:为了实现定子的全面均匀冷却和定子绕组的电缆中的磁场的最佳控制,通过改进具有转子的类型的发电机,其可以围绕轴线旋转 的旋转并被定子包围,并且具有定子绕组,其由绝缘电缆形成并且布置在转子的层叠的薄金属板内部,并且在轴向方向上延伸到金属板内部并且在端面上形成绕组头 金属板外面。 解决方案:将具有层叠的薄金属板和定子绕组的定子放入壳体中,其密封密封而不包含转子。 套管的内腔充满冷却液。
