Patent number: 11223307Abstract: 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.
