Embodiment 1
[0039] as attached figure 1 As shown, a specific embodiment of the potting structure at the end of a motor winding, including:
[0040] The outer potting tool 1 and the inner potting tool 2 are coaxially arranged on both sides of the stator core 3 with a hollow cylindrical structure, and a potting area 5 is formed between the outer potting tool 1 and the inner potting tool 2. The stator winding end 4 is located in the potting area 5; the outer potting tool 1 and the inner potting tool 2 are both made of metal materials, and the two cooperate to form the potting area 5 for potting the end of the motor winding; wherein, the outer potting The structural diagrams of tooling 1 and inner potting tooling 2 are attached figure 2 to attach Figure 5 shown;
[0041] The potting glue 6 formed in the potting area 5 and covering the outer periphery of the stator winding end 4 is used to reduce the temperature rise of the motor winding end.
[0042] The potting glue 6 made of high ther...
Embodiment 2
[0047] as attached Figure 6 As shown, a specific embodiment of a motor winding end potting method, comprising the following steps:
[0048]A) Make the outer potting tool 1 and the inner potting tool 2 respectively with hollow cylinder structure, arrange the outer potting tool 1 and the inner potting tool 2 coaxially on both sides of the stator core 3, and the outer potting tool A potting area 5 is formed between the tooling 1 and the inner potting tooling 2; potting glue 6 is prepared;
[0049] B) After the outer potting tool 1, the inner potting tool 2 and the potting glue 6 are all prepared, the stator winding end 4 located on both sides of the stator core 3 and in the potting area 5 is poured and potted until The potting glue 6 completely covers the outer surface of the stator winding end 4;
[0050] C) After the potting glue 6 is dry and the outer potting tool 1 and the inner potting tool 2 are removed, then the motor is assembled. The structure of the motor after the f...
Embodiment 3
[0054] as attached Figure 7 Shown, a kind of specific embodiment of the motor that is made by above-mentioned method, comprises:
[0055] Stator core 3, rotor core 7 and rotating shaft 10 arranged coaxially with each other from outside to inside;
[0056] The non-drive end cover 8 sleeved on the rotating shaft 10 and located at the non-drive end of the motor, and the drive end cover 9 sleeved on the rotate shaft 10 and located at the drive end of the motor, the stator core 3, the non-drive end cover 8 and the drive end The end cover 9 forms a closed structure of the motor;
[0057] The windings wound on the stator core 3 , the parts of the winding protruding from both sides of the stator core 3 form the stator winding end 4 , and the outer circumference of the stator winding end 4 is coated with potting glue 6 . The potting compound 6 is located between the stator core 3 and the non-drive end cover 8 , and between the stator core 3 and the drive end cover 9 .
[0058] The ...
