Embodiment 1

[0039] Such as figure 1 As shown, the stator provided in this embodiment includes: a plurality of coil structures 300 and a plurality of sleeves 330; one end of one coil structure 300 and one end of another coil structure 300 are respectively sleeved in the sleeves 330 and cooled Press tightly; and the two ends are in contact.

[0040]In the stator provided in this embodiment, the coil structure 300, the sleeve 330 and the coil structure 300 are sequentially connected by putting the ends of the two coil structures 300 in the sleeve 330 respectively, and then compressing them by cold pressing. . The cold-pressed connection replaces the welding method, which generates less heat and reduces the impact on the insulation structure of the outer layer of the coil structure 300; in addition, the cold-pressed connection is simple in process and easy to operate, reducing errors in the welding process, and at the same time , The cold-pressed connection method makes the coil structure 3...

Embodiment 2

[0053] The motor provided in this embodiment includes: the stator provided in Embodiment 1.

[0054] In the motor provided by this embodiment, the welding method is replaced by cold-press connection, so that the two coil structures 300 are connected to the sleeve 330, reducing the number of welding spots, thereby reducing the influence on the resistance of the motor, so that the motor can rotate effectively. Wherein, the structure and beneficial effects of the stator have been described in detail above, and will not be repeated here.

Abstract

The invention relates to the technical field of motors, and particularly relates to a stator and a motor. The stator includes a plurality of coil structures and a plurality of sleeves, wherein one endpart of one coil structure and one end part of another coil structure are separately sleeved in the sleeves and are pressed tightly by cold pressing; and the two end parts are in contact. According to the stator, the technical problems that the two coil structures cause damages to the insulation structures on the coil structures due to a welding mode, and are complex in process and high in operation requirements, and the welding spots may affect the coil structures can be solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator and a motor. Background technique [0002] At present, in the stator, the inter-turn connection and the inter-pole connection at the end of the coil structure adopt a welding process, and the two coil structures can be connected by welding to form a path. [0003] However, connecting by welding can easily cause the end faces of the two coil structures to be heated in a large range, and easily damage the insulating material outside the coil structure; in addition, the process of connecting the two coil structures by welding is complicated and requires a strong operating level to complete Welding, and the resulting solder joints are likely to affect the coil structure, making the resistance of the motor uneven. Contents of the invention [0004] The purpose of the present invention is to provide a stator to solve the technical problems that the insulation structure on th...
