Embodiment Construction

[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0022] A method for pasting windings on the outer surface of a slotless stator armature, comprising the following steps:

[0023] (1) Select the size of the winding die through repeated tests;

[0024] The winding die of the conventional slotless armature coil is to wind a single independent coil, so the winding die is generally equipped with a set of pressure plates and mold cores. For continuous winding coils, in addition to considering the size of a single coil, it also needs to be considered The position of the head of the wire connected to the coil and the length of the wire. The preliminary size determination of the winding die is mainly based on formula a and formula b:

[0025] H=Dy / Z………………(a)

[0026] L=L 1 +h…………………(b)

[0027] Among them, H is the width of the winding die; D is the outer circle of the iron core; y i...

Abstract

The invention provides a wire attaching method for a winding on the outer surface of a slotless stator armature. The method includes the following steps of selecting the size of a winding mold through trial and error, winding independent coils or continuously-wound coils, conducting positioning on a wiring tool through two pins, evenly distributing the coils on the wiring tool according to lineation positions, brushing the distributed coils with organic silica gel to fix the coils and form a coil winding, taking down the coil winding on the wiring tool, arranging the coil winding on the outer surface of the armature, evenly distributing the coils of the winding along the circumference of an iron core, binding the outer circle through 556 adhesive tape, and preliminarily fixing the appearance through a thermal shrinkage thin film. By means of the wire attaching tool and methods of preliminary solidification and the like, the difficulty of wire attaching on the outer surface of the slotless stator armature is lowered, it is ensured that winding elements are evenly distributed along the circumference of the iron core, product consistency is improved, the percent of pass of machining of the outer surface of a slotless stator is increased, and manual and man-made individual operation is reduced.

Description

technical field [0001] The invention relates to the technical field of brushless motor manufacturing, in particular to a wire pasting method for windings on the outer surface of a slotless stator armature. Background technique [0002] In the brushless motor, the stator armature is generally composed of iron core, coil winding, etc. According to the structure of the iron core, it can be divided into slotted and slotless. The slotless stator armature of the brushless motor can reduce the cogging torque and improve the low speed. smooth running. [0003] The stator slotless armature structure requires the winding to be directly attached to the outer circle of the iron core to ensure that the coils are evenly distributed and the slot distribution rate is high. At present, there are some servo motors with a slotless structure. In the armature forming process of this kind of products, the outer circle single coil wire bonding method is adopted: first wind the single coil, and th...
