A starting apparatus is specified for at least two synchronous machines (G), which starting apparatus comprises an exciter unit (SES, SESX) which is provided for each synchronous machine (G) and is associated with the respective synchronous machine (G), with the respective exciter unit (SES, SESX) being connected to the field winding of the associated synchronous machine (G). Furthermore, a superordinate control unit (DCS) is provided, with the superordinate control unit (DCS) being connected via a communication link to each exciter unit (SES, SESX). Furthermore, the starting apparatus comprises at least one stator feed unit (SSD) and one switching device (SSB), which is provided for each stator feed unit (SSD) and is associated with the respective stator feed unit (SSD), in which case the respective switching device (SSB) can be connected to the associated stator feed unit (SSD), the respective switching device (SSB) can be connected to at least one synchronous machine (G), and the switching devices (SSB) can be connected to one another when there are a plurality of switching devices (SSB). In order to simplify the implementation and the maintenance, and in order to reduce the susceptibility to defects, the exciter units (SES, SESX) are connected to one another via a ring communication link (1), each stator feed unit (SSD) is connected to the ring communication link (1), each stator feed unit (SSD) is connected via a communication link to the associated switching device (SSB), and the exciter units (SESX) which are associated with the stator feed units (SSD) are each connected via a communication link to a switching device (SSB).
