ABSTRACT:
A rotating electrical machine, especially a turbogenerator, includes a rotor and a stator, which concentrically surrounds the rotor and is terminated at each of the two axial ends by a laminated press plate (14), which is constructed from a stack of individual press plate laminates (30). The electrical properties are improved by providing the press plate laminates (30) at least partially with slits (26) for reducing the eddy current losses.
