Novel magnet yoke air guide block

The utility model discloses a novel magnet yoke wind guide block, which belongs to the technical field of motors, the wind guide block is detachably connected with a magnetic pole, the lower end of the wind guide block is fixedly connected with a magnet yoke section through a welding seam, a spigot structure used for limiting the circumferential movement of the wind guide block is arranged between the wind guide block and the magnet yoke section, and a ventilation duct is formed between two adjacent wind guide blocks. The seam allowance structure is arranged between the air guide block and the magnet yoke section, and the seam allowance structure and the weld joint share the acting force of a magnetic pole together, so that the stress amplitude of the weld joint is reduced, and the risk brought to a unit by fatigue damage of the weld joint is effectively prevented. 本实用新型公开了一种新型的磁轭导风块，属于电机技术领域，导风块与磁极可拆卸连接，导风块下端通过焊缝与磁轭段固定连接，所述导风块与磁轭段之间设置有用于限制导风块周向运动的止口结构，相邻两个导风块之间形成通风沟。本实用新型通过在导风块与磁轭段之间设置止口结构，由止口结构与焊缝共同分担磁极作用力，
