ABSTRACT:
An electrical machine includes a housing and a shaft which is housed in the housing by means of a fixed bearing and a free bearing. The fixed bearing is formed by two grooved ball bearings which are respectively prestressed in opposite directions by springs. Thus, at least one of the two grooved ball bearings is always prestressed independently of the axial force exerted on the shaft, such that the required radial stiffness of the fixed bearing is guaranteed.
