  • Patent number: 6198193
    Abstract: A configuration for supporting a first part of a stator of an electric machine, in particular a turbogenerator, at a second part of the stator, in which the first part and the second part are at a distance from one another and at least partially surround an axis of rotation of a rotor shaft in a rotation direction. The two parts are each supported against one another by an integral supporting element at least at three locations distributed around the axis of rotation. The supporting elements each have a material strip which is bent in a single plane, between their ends, so that the distance between the two parts is variable when the material strip is subjected to bending deformation in the axial direction and radial direction of the turbomachine. The support is rigid in the tangential direction due to the stiffness of the material strips transversely with respect to the bending course. Due to the bent metal strips, the configuration can be produced in such a way that it saves space and is cost-effective.

  • Patent number: 5053663
    Abstract: An electric machine includes a stator lamination packet having an inner periphery defining a stator bore, a laminted screening packet with an inner periphery and lamination segments formed of magnetic material, and a slot and tooth system disposed on and connected to the inner periphery of the screening packet, the slot and tooth system being at least partly formed of nonmagnetic material and having successive slot teeth defining bar receiving slots with a slot bottom, and an air-gap winding on the inner periphery of the stator lamination packet having winding bars with winding bar sides oriented toward the stator bore, the winding bars being inserted in the bar receiving slots with a radial protrusion beyond the slot teeth.
