Combination of AC motor and converter unit and wind power generation equipment

The invention relates to a rotary machine (3) comprising a stator (11) and a rotor (8) that can rotate about an axis of rotation (10). The stator (11) is mechanically divided into stator segments (14), each of which cover a respective section in relation to the axis of rotation (10). The respective coils (12) of just one individual multi-phase rotary system are arranged in the stator segments (14). The stator segments (14) each have only the connections (15) for connecting the phase lines (16) of an individual multi-phase rotary system. The connections (15) are connected to the coils (12). Theconverter unit (4) has multiple sub-units (4a, 4b) which can be operated independently of one another, each forming an individual multi-phase rotary system. The number of phases of the sub-units (4a,4b) corresponds to the number of stator segments (14). The connections (15) of the stator segments (14) are each connected to a sub-unit (4a, 4b). The stator segments (14) form groups of directly successive stator segments (1
