Abstract: The invention relates to an arrangement (10) for feeding electrical energy into an energy supply system (100). The invention provides that the arrangement has a generator (20) with electrically isolated winding systems (30), the arrangement has at least two frequency converters (40, 41, 42) with isolated intermediate circuits (60), wherein each frequency converter is connected directly or indirectly to a winding system (30) of the generator, the arrangement has at least one control device (80), to which the frequency converters are connected for actuation thereof, and the frequency converters, on actuation by the control device, feed current by means of a voltage with a multi-level characteristic into the energy supply system (100).

Abstract: A meat cutter, a blade head and an associated cutter blade (11, 12) are provided to reduce the complexity with respect to assembly and disassembly and the diversity of the parts, and the potential danger during assembly and disassembly. This is achieved according to the invention by providing the blade foot (2) of the cutter blade (1, 11, 12) with a toothing structure (8) with projections (9) and recesses (10), which point towards the drive shaft (19) and by means of which the cutter blade (11, 12) can be positioned in a rotationally secure manner in a matching toothing structure (14), by being pushed on in the axial direction.
