摘要
A permanent-magnet direct-drive wind power generator, a system and a stator thereof are provided. The stator includes a stator support, a stator iron core arranged around an outer peripheral wall of the stator support and a blade side tooth pressing plate arranged on an axial end face at a blade side of the stator iron core. At least one first air hole is provided in the outer peripheral wall of the stator support, and at least one second air hole is provided in the blade side tooth pressing plate, and further includes at least one air flow passage via which the first air hole and the second air hole are in communication with each other, and the air flow passage passes through the interior of the stator iron core. The stator can introduce air flow inside the stator support to an axial end face of the stator iron core.
