Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-diameter electric motors face transportation difficulties and increased costs due to their size, as existing solutions do not effectively manage the large outer diameter, exceeding transportation limiting values.
Innovation Solution
A stator support system that divides the stator ring into segments in the circumferential direction, allowing each segment to be machined from steel and connected using a modular design with connecting arms and fastening members, ensuring dimensions are within transportation limits, facilitating assembly and disassembly, and enabling separate transportation of components.

Engineering Contradiction Analysis
1Power
If the electric motor outer diameter is increased to achieve larger single-machine power, then the power output is improved, but the transportation difficulty and cost increase due to exceeding transportation limiting values
Solution Approach 1:
The stator support is divided into multiple stator support segments in the circumferential direction, each segment having a smaller outer diameter that can be transported separately. These segments are then assembled together to form the complete stator support for large-diameter electric motors, enabling transportation of components within limiting values while maintaining the capability to support large-power motors.
2Power
If the electric motor outer diameter is increased to achieve larger single-machine power, then the power output is improved, but the cost of the electric motor increases
Solution Approach 1:
Dividing the stator support into transportable segments reduces transportation costs and enables standard shipping methods. The modular design also allows for more efficient manufacturing and assembly processes, reducing overall production costs while enabling large-diameter motor construction.
3Ease of operation
If the stator ring is divided into segments in the circumferential direction, then the transportation difficulty is reduced by controlling dimensions within transportation limits, but the device complexity increases due to modular design with connecting arms and fastening members
Solution Approach 1:
The stator support is segmented into multiple sections with connecting arms and fastening members, enabling transportation of smaller components while maintaining structural integrity when assembled. This segmentation allows standard transportation methods to be used for large-diameter motor components.
Solution Approach 2:
Multiple stator support segments are combined through connecting arms and fastening members to form the complete stator support structure. This merging of segmented components recreates the functionality of a solid large-diameter stator support while enabling modular transportation and assembly.

AI summary
The present disclosure relates to a stator support and a stator. The stator support is applied to a large-diameter electric motor. The stator support includes a stator shaft, coaxially connectable to a fixing shaft of the electric motor; a supporting assembly, coaxially arranged at an outer circumference of the stator shaft; a stator ring, connectable to a stator iron core of the electric motor, in which the stator ring includes two or more stator ring segments continuously distributed in a circumferential direction of its own, each of the stator ring segments is in a sector shape, and the two or more stator ring segments are coaxially arranged at an outer circumference of the supporting assembly. In the stator support, at least the stator ring connected with the stator iron core of the electric motor is divided into two or more stator ring segments in the circumferential direction, so that a maximum contour dimension of each of the stator ring segments can be controlled within the transportation limiting value, thereby solving the difficult transportation problem of the stator support of the large-diameter electric motor.
