Punching sheet, winding type iron core and motor

The invention discloses a punching sheet, a winding type iron core and a motor, and relates to the technical field of motors. The punching sheet comprises a yoke part, tooth parts and bending grooves.The multiple tooth parts are distributed on one side of the yoke part at intervals, and a wire groove is formed between every two adjacent tooth parts; one or more bending grooves are formed in the joint of the yoke part and the wire grooves; each bending groove is of an included angle structure with an opening facing one side of the corresponding wire groove, and the diagonal center line of eachincluded angle coincides with the bisector of the corresponding wire groove. The winding type iron core is formed by spirally winding the punching sheet into a circular structure and laminating and combining more than one circular structure. The motor comprises the winding type iron core. The yoke part of the punching sheet is provided with the bending grooves, so that the winding deformation width of the yoke part is red
