AI Technical Summary
Technical Problem
In existing motor designs, the circuit board is inaccurately positioned relative to the stator, leading to reduced motor control efficiency and increased vibration due to the 'three-point soldering' connection method, which results in poor phase change consistency.
Method used
A stator structure with a positioning part and a positioning coupling part on the circuit board, allowing for a 'two-point soldering' connection that restricts displacement, improving positioning accuracy and reducing vibration by using a 'triangular' deployment of pins and through holes.
Benefits of technology
The improved stator structure ensures accurate positioning of the circuit board, enhancing motor control efficiency and reducing vibration by maintaining consistent phase change points.

Abstract
This application relates to the field of motors, and specifically, to a stator structure for a motor. The stator structure includes: a stator main body (1) having a first pin (11), a second pin (12), and a positioning part (13), the positioning part being spaced apart from the first pin and the second pin; and a circuit board (2) having a first through hole (21), a second through hole (22), and a positioning coupling part (23), the first through hole being suitable for being fixedly connected to the first pin, and the second through hole being suitable for being fixedly connected to the second pin, to implement an electrical connection between the stator main body (1) and the circuit board (2), where the positioning part (13) and the positioning coupling part (23) are configured to be detachably connected to each other at least in an assembled state, to generate, at least in an extension plane of the circuit board (2), a constraint that restricts displacement of the circuit board (2) relative to the stator main body (1). Through an embodiment of this application, the circuit board and an electronic component thereof can be connected to the accurate positions of the stator main body.
