The Chinese invention patent is disclosed, the publication number is: CN205901458U, patent name: the utility model provides a stator core and chain stator iron core piece, application date: 20160805, it discloses a stator core and chain stator iron core piece, solves the problem that there is a protrusion after the chain iron core structure of prior art forms the circle, can't closely cooperate with the casing. Chain stator iron chip wherein is used for stator core after the one-tenth circle, including the profile of tooth unit that a plurality of connected in order, connect through connecting portion between two adjacent profile of tooth units the inboard of connecting portion is equipped with the groove of turning back the outside of connecting portion is equipped with the transition structure of indent, makes chain stator iron chip becomes the circle after, the whole of transition structure does not surpass the excircle of stator core after the one-tenth circle. According to the chain type stator iron chip, the transition structure is additionally arranged between the two tooth-shaped units, so that the transition structure is controlled within the diameter of the stator iron core after the chain type stator iron chip is rounded, the chain type stator iron chip is in surface contact with the shell, the contact area is increased, the stator iron core is ensured to be tightly matched with the shell, and the chain type stator iron chip can be applied to non-plastic package shell motors, such as servo motors and the like.
As shown in fig. 2, the conventional iron core is a single-tooth flying-inserted type winding wire, and a cavity is designed according to the prior art, which easily causes collapse of a bottom layer copper wire during winding, which causes no additional winding, and causes excessive interlayer variation due to intersection of the winding wires.
