Description

Stator assembly of motor

Technical Field

The utility model relates to a stator assembly of a motor, and belongs to the field of motor parts.

Background

The motor is generally assembled by a stator assembly, a rotor assembly, and a rotating shaft. The framework of the stator assembly of the motor is an important part for winding the coil, and after the coil is wound, two lead ends led out need to be welded with a circuit board. However, the existing lead wire end is not limited after being led out, so that a corresponding lead wire needs to be found during welding, and the welding efficiency is reduced. And the existing welding of the lead terminal and the circuit board can only be manually welded, if the lead terminal can be positioned, special welding equipment can be adopted for welding, and the welding efficiency is further improved.

Disclosure of Invention

The utility model aims to provide a stator assembly of a motor, which has the advantages that a coil leading-out end can be limited on a framework, the subsequent welding work is convenient, the positioning is provided for the future equipment welding, and the welding efficiency is improved.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a stator module of motor, includes stator, preceding skeleton and back skeleton, and preceding skeleton and back skeleton cartridge are at the both ends of stator, and the inner wall of preceding skeleton all has a plurality of wire winding end, and the inner wall of preceding skeleton is located and has the ply-yarn drill between the adjacent wire winding end.

Preferably, one end of the line card is provided with a clamping mouth groove which is axially opened. Two lead terminals are limited after the winding is convenient.

Preferably, the slot middle section and the slot bottom of the bayonet slot are provided with expanding slots. One lead end is clamped in the expansion groove at the middle section of the groove, and the other lead end is clamped in the expansion groove at the bottom of the groove to limit the two lead ends.

Preferably, a plurality of inserting columns are arranged at one ends of the front framework and the rear framework, and penetrating inserting grooves matched with the inserting columns in structure are formed in the inner wall of the stator. The front framework and the rear framework adopt a plug-in mounting structure, so that the installation is convenient.

Preferably, a coil is wound on the winding end, and two lead ends of the coil are clamped in the bayonet grooves and are electrically connected with a circuit board fixed at the outer end part of the front framework. The circuit board is positioned and installed through a plurality of guide posts of the framework, and is just close to the wound coil, so that the lead and the circuit board can be conveniently welded.

By adopting the structure, the utility model can wind the coil at the corresponding winding end, pull out the two leads, clamp the two leads on the wire clip, and conveniently find the corresponding leads during welding. And because the lead wire end is positioned, special welding equipment can be adopted for welding, and the welding efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the following examples, which are given in conjunction with the accompanying drawings.

The first embodiment is as follows: referring to fig. 1-3, a stator assembly of a motor includes a stator 1, a front frame 2 and a rear frame 3, wherein one end of the front frame 2 and one end of the rear frame 3 of an annular structure are respectively provided with eight plug-in posts 6 which are uniformly distributed, the inner wall of the stator 1 is provided with eight through plug-in slots 11 which are structurally matched with the plug-in posts 6, and the front frame 2 and the rear frame 3 are respectively plugged at two ends of the through plug-in slots 11 of the stator 1 through the respective plug-in posts 6. The installation is convenient, and each position can be installed during the installation.

In this embodiment, the inner wall of the front frame 2 has eight winding ends 4, the winding ends 4 are radially extending inward, and the outer side of the winding ends is an extended structure, so that winding is facilitated. The inner wall of the front bobbin 2 has four wire clips 5 between adjacent winding ends 4. Referring to fig. 3, the line card 5 has an axially open bayonet groove 51 at one end, and the intermediate groove section and the groove bottom of the bayonet groove 51 have expansion grooves 52.

Referring to fig. 4, when the device is installed, a coil 7 is wound on each winding end 4, wherein two lead ends 71 extending from four coils 7 are respectively clamped in the corresponding clamping mouth grooves 51 and positioned in the expanding grooves 52 at the middle section and the bottom of the groove, the circuit board 8 is clamped on the front framework 2, and the lead ends 71 are fixed on the circuit board 8 at the outer end part of the front framework 2 and are electrically connected.

Referring to fig. 5, in the utility model, as the wire clip 5 is arranged between the adjacent winding ends 4 on the inner wall of the front framework 2, and the wire clip 5 is used for fixing the lead ends 71 extending out of the coil 7, corresponding leads can be easily and conveniently found for welding during welding, thereby improving the welding efficiency. Moreover, since the lead terminal 71 is limited, the manipulator can find the corresponding lead, instead of positioning the lead terminal 71 in the prior art. Therefore, the special welding equipment can be produced subsequently to replace the existing manual welding, and the production efficiency is further improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
