Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stators with multi-phase windings face challenges in managing terminal line arrangements, leading to increased radial dimensions and potential interference issues.
Innovation Solution
A stator design featuring a guide member on one side of the stator core that guides terminal lines in a circumferential direction, with a collecting portion to consolidate terminal lines, reducing the radial extent and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal lines are guided in circumferential direction on guide member, then radial dimension increases, but terminal line management becomes easier
Solution Approach 1:
The patent changes the guiding direction from radial to axial dimension. The guide member guides terminal lines in the axial direction rather than circumferential direction, allowing terminal lines to be collected at one end of the guide member in the axial direction, thus avoiding radial expansion while achieving effective terminal line management
Solution Approach 2:
The patent merges multiple terminal lines into a single collected position. The guide member collects all terminal lines at one end in the axial direction, consolidating what would otherwise be dispersed radial arrangements into a single organized location, simplifying management without increasing radial dimension
2Adaptability or versatility
If more notches are provided on guide member for terminal lines, then terminal line arrangement becomes more flexible, but device complexity increases
Solution Approach 1:
The patent extracts the guiding function from multiple distributed notches and concentrates it into a single axial guide structure. Instead of providing multiple notches around the circumference, the guide member provides a single axial path that collects all terminal lines at one end, reducing structural complexity while maintaining arrangement flexibility
Solution Approach 2:
The guide member serves multiple functions: it guides terminal lines in the axial direction, collects all terminal lines at one end, and provides organization without requiring multiple specialized notches. This multi-functional design reduces the number of structural elements needed

AI summary
In a stator, coils of multiple phases are wound around a stator core via an insulator. A guide member is provided on one side of the stator core in the axial direction and guides the terminal line of the coil in the circumferential direction at a position overlapping the coil in the axial direction. The guide member has a collecting portion which collect the terminal lines at one place in the circumferential direction. The terminal line of the coil arranged in a vicinity of the collecting portion in the terminal line is a non-drawn terminal wire that is collected in the collecting portion without being drawn on the guide member in the circumferential direction.
