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 ...

Abstract

The invention provides a method for pasting windings on the outer surface of a slotless stator armature, which comprises the following steps: selecting the size of a winding die through repeated tests; winding independent coils or continuous winding coils; positioning with two pins on the wiring tool ; Distribute the coils evenly on the wiring tool according to the marking position; brush the organic silica gel on the distributed coils to fix the coils to form a coil winding; remove the coil windings on the wiring tool and arrange them on the outer surface of the armature, and the coils of the winding Evenly distributed along the circumference of the iron core; use 556 tape to bind the outer circle and use heat shrinkable film to initially fix the shape. The present invention reduces the difficulty of affixing wires on the outer surface of the slotless stator armature through methods such as wire affixing tooling and preliminary curing, ensures that the winding components are evenly distributed along the circumference of the iron core, improves product consistency, and improves the pass rate of the outer surface processing of the slotless stator. Reduce manual personalization operations.

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...
