ABSTRACT:
The vertical-axis electrical machine of umbrella design has a disc-shaped rotor (4), the combined thrust and guide bearing (12) which is mounted at the disc underside. The bearing rests on a bearing support structure (17), which has the shape of a hollow truncated cone and is supported directly on the foundation (1). This arrangement is distinguished by low design height. Elongations of the bearing support structure (17) caused by temperature are converted without loss of stiffness and centering into axial displacement of the end of the hollow truncated cone (17) on the bearing side.
