Rotor with a balancing flange, rotor assembly with at least one rotor, and turbomachine with at least one rotor or with a rotor assembly

A rotor for integration in a turbomachine, the rotor comprising:

• a rotor base body, wherein, on the rotor base body in a rotor outer space of the rotor, at least one blade element or airfoil is mounted,
• wherein the rotor base body extends in a radial direction of the rotor and comprises a connecting section, which extends in an axial direction of the rotor for connection to at least one further rotor and separates the rotor outer space from a rotor inner space of the rotor, the axial direction being in a longitudinal direction of the turbomachine,
• wherein the connecting section comprises, in the axial direction of a front side, a balancing flange which extends radially outward from the connecting section and, at least in sections, extends in the radial direction in the rotor outer space, wherein the balancing flange is configured for compensating an imbalance of the rotor.
