摘要： Disclosed are a permanent-magnet direct-drive wind power generator, a system and a stator thereof, wherein the stator comprises a stator bracket (1), a stator iron core (8) arranged on the peripheral wall of the stator bracket and a paddle side tooth pressing plate (6). The paddle side tooth pressing plate is arranged on a paddle side axial end face of the stator iron core. At least one first air hole (2) is formed in the peripheral wall of the stator bracket. At least one second air hole (5) is formed in the paddle side tooth pressing plate. The stator further comprises at least one air flow passage (9) used for linking the first air holes with the second air holes. The air flow passage penetrates through the interior of the stator iron core. The electric motor can self-adaptively dry itself, the service life of permanent magnet poles is prolonged, an "insulation level reduction" of components inside the electric motor is prevented, the risk that the electric motor is corroded by severe air flow is lowered, and insulation reliability is improved.

摘要： A motor slot wedge with a sealing structure and a combination device. The structure of the motor slot wedge (1) is the following: a groove is formed in the outer wall (13, 14) of the slot wedge; thermal expansion materials (8) are arranged in the groove; the thermal expansion materials (8) are in contact with the inner wall (10, 11, 12) of an iron core tooth groove after heating expansion. The combination device includes a motor iron core with the iron core tooth groove and the motor slot wedge (1) with the sealing structure. By forming the groove in the outer wall (13, 14) of the slot wedge (1) and filling the groove with the thermal expansion materials (8), the sealing structure is formed between the slot wedge (1) and the inner wall of the tooth groove of the iron core, moisture is prevented from entering the interior of the tooth groove of the iron core and damaging the insulating structure, and paint loss after vacuum pressure impregnation could be blocked.
