Stator Segment Segmentation for Ring Generator Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind turbines with ring generators require large stator diameters and complex on-site assembly of stator parts, leading to inefficient transportation and time-consuming installation due to the need for gearbox-driven rotational speed increase and manual soldering and bracing of conductors.
Innovation Solution
The stator segment and device design includes a base element with pre-assembled coil elements and a connecting coil element with adjustable regions, allowing for pre-assembly at the manufacturing site and easy connection at the installation site, reducing the need for on-site soldering and bracing, and enabling efficient transportation of large-diameter stators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the stator diameter is increased to improve electromagnetic performance and reduce gearbox requirements, then the relative velocity in the contact area between rotor and stator is increased, but transportation difficulty increases
Solution Approach 1:
The stator is divided into multiple stator segments that can be manufactured separately with smaller diameters, making transportation easier. These segments are then assembled on-site to form the complete large-diameter stator structure, thereby resolving the contradiction between achieving high electromagnetic performance through large diameter and the difficulty of transporting such large structures.
2Ease of operation
If the stator is divided into multiple segments for easier transportation, then transportation ease is improved, but assembly complexity and installation time increase
Solution Approach 1:
The coil elements are pre-assembled and pre-positioned on the stator segments during manufacturing, with connection regions prepared in advance. This preliminary action ensures that when segments are assembled on-site, the connections between segments can be quickly made without complex on-site assembly operations, thereby reducing assembly complexity and installation time while maintaining transportation ease.
3Ease of manufacture
If conventional assembly methods are used for stator segments, then manufacturing simplicity is maintained, but installation time and labor intensity increase due to manual soldering and bracing
Solution Approach 1:
The invention replaces manual soldering and bracing operations with a mechanical connection system using connection regions and connecting coil elements. The coil elements are mechanically attached to the base elements at predefined connection regions, eliminating the need for time-consuming manual soldering and bracing operations. This substitution maintains manufacturing simplicity while dramatically increasing installation speed and reducing labor intensity.
