In a component for receiving and clamping a rotor, a ring assembly enclosing a hollow space includes rings lying one inside the other and with connectors extending radially through the ring assembly, by which the rings are connected to one another in a rotationally fixed manner. At least two clamping elements projecting into the hollow space are attached to the ring assembly, which form a receptacle for the rotor with clamping surfaces. There are also weights on the ring assembly for centrifugal force compensation.
