Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stators with multiple segments face challenges in winding coils due to narrow spaces around teeth, leading to increased vibration and reduced productivity.
Innovation Solution
A stator design featuring connection cores arranged in an annular shape, with pieces connected via bendable portions to form a circular arc shape, allowing for improved coil winding and reduced vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the stator is formed with multiple segments in a conventional circular arc shape, then the total number of windings and number of salient poles can be adjusted to prevent noise caused by vibration, but the space around the teeth becomes narrow making it difficult to wind the coils and productivity cannot be improved
Solution Approach 1:
The stator is divided into multiple segments (first through fourth segments) that are connected via connection cores. This segmentation allows each segment to be manufactured and wound independently, improving productivity while maintaining the overall circular arc configuration needed for vibration control.
Solution Approach 2:
Connection cores with connection portions are introduced as intermediary elements to join the multiple stator segments. These connection portions provide flexibility and space for coil winding while maintaining the structural integrity and circular arc shape of the overall stator assembly.
2Stability of the object's composition
If the segments are formed in a circular arc shape to control vibration, then the stator can maintain its structural integrity, but the space around the teeth is narrow making coil winding difficult
Solution Approach 1:
The stator is divided into multiple segments connected by connection cores, allowing each segment to be manufactured separately with easier coil winding access, while the assembled structure maintains the required circular arc shape for structural integrity.
Solution Approach 2:
The connection portions are designed with bendable characteristics, allowing the stator segments to be assembled in a multi-dimensional process where the connection portions can be bent to achieve the final circular arc configuration, providing manufacturing flexibility.
