AI Technical Summary
Technical Problem
Existing motor stator designs with axially extending conductor connection sections result in excessive axial dimensions, increased manufacturing costs, and complex connection structures due to the need for axial offset and stacking of busbars.
Method used
The conductor connection sections of the motor stator are arranged circumferentially and extend radially, with busbars positioned in the same axial plane, eliminating the need for axial offset and stacking, and featuring a radial design that minimizes axial dimensions and simplifies manufacturing.
Benefits of technology
This design reduces the axial dimension of the motor stator, decreases manufacturing complexity, and lowers production costs while maintaining electrical connectivity and safety.

Abstract
A motor stator is provided, comprising an iron core (1), a winding (2), and several busbars (3, 4) assembled together. The winding (2) is attached to the iron core (1) and includes several conductor connection sections (2e). The multiple conductor connection sections (2e) are spaced apart from each other in the circumferential direction of the motor stator. Each conductor connection section (2e) extends along the radial direction of the motor stator. The different conductor connection sections (2e) extend along different radial directions. Each busbar (3, 4) is electrically connected to the corresponding conductor connection section (2e).In this way, compared to a solution where the conductor connection sections extend along the axial direction of the motor stator, the axial dimension of the motor stator can be significantly reduced, since in the solution of the present application all conductor connection sections extend along the radial direction of the motor stator. Furthermore, a motor comprising the aforementioned motor stator is provided.
