Electrodynamic machine comprising a shaft supported by a three point bearing and use of a third bearing for supporting a shaft

摘要

The machine (1) has two main bearings (6, 7) for supporting rotatably positioned shaft (4), where the bearings are axially spaced from one another. An additional bearing (8) absorbs radial forces that are generated by the shaft, where maximum rotation speed of the shaft is 50 percent of the rotational speed to create natural bending vibration at the shaft, where the shaft is rotatably supported by main bearings. The main bearings are axially spaced from one another along the shaft by an axial main bearing distance (d1).
