Abstract
A rotary machine includes a rotor rotatable about a rotation axis and a stator mechanically divided into stator segments, each covering a respective section in relation to the rotation axis. Coils of one individual multi-phase rotary system are respectively arranged in the stator segments, each having terminals which connect phase lines of an individual multi-phase rotary system and are connected to the coils. A converter unit includes multiple subunits operated independently of one another, each forming an individual multi-phase rotary system. The number of phases of the subunits corresponds to the number of stator segments. The terminals of the stator segments are each connected to a subunit. The stator segments form groups of directly successive stator segments when viewed about the rotation axis. The terminals of the stator segments are connected to the same sub-unit within each group, but connected to different sub-units from group to group of stator segments.
