摘要： A stator used for a motor, the motor and a ventilation cooling method for the motor. The stator includes concentrated windings, and at least two wedge blocks are arranged at the gaps between the adjacent concentrated windings. The at least two wedge blocks are distributed on the concentrated windings in a staggered manner to form a first ventilation path. Therefore, the concentrated windings can be cooled effectively, the concentrated windings are effectively constrained in the circumferential direction by means of the at least two wedge blocks, the service life of the motor is further prolonged, and the reliability of the motor is improved.

摘要： The present disclosure provides a control method, device and system for a wind turbine. The control method includes: acquiring current working conditions of a power system, a yaw system and a communication system of the wind turbine when a typhoon warning signal is received; determining a target control strategy corresponding to the current working conditions according to a preset corresponding relationship between control strategies and working conditions of the power system, the yaw system and the communication system, wherein the control strategies may include an active windward strategy for controlling the yaw system to face typhoon wind direction, a controlled passive leeward strategy for controlling the yaw system to face opposite to the typhoon wind direction, and a passive leeward strategy for adjusting the yaw system to face opposite to the typhoon wind direction; and controlling the wind turbine by using the target control strategy.

摘要： A motor slot wedge having a sealing structure is provided. An outer wall of the slot wedge is provided with a groove, and a thermal expansion material is provided in the groove, and the thermal expansion material, after expanding with heat, is in contact with an inner wall of an iron core tooth slot. A combination structure of a motor slot wedge having a sealing structure and a motor iron core is further provided, and includes the motor iron core having an iron core tooth slot and the motor slot wedge. A sealing structure is formed between the slot wedge and the inner wall of the slot of the iron core, thereby preventing the moisture from entering the inside of the slot of the iron core and damaging the insulation structure accordingly, and preventing varnish loss after varnish vacuum pressure impregnation.
