Motor Base With Deformable Connecting Element for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor bases fail to effectively eliminate vibration and noise due to the placement of vibration-reducing materials around the periphery, which allows vibrations to transfer and complicates the manufacturing process.
Innovation Solution
An integrally formed motor base with a deformable connecting element between the central and surrounding portions, utilizing over molding or insert molding to incorporate a buffer component, which enhances vibration and noise reduction while simplifying assembly and providing waterproofing and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vibration eliminating material is disposed around periphery of motor base, then motor base structure is simple, but vibration eliminating effect is insufficient
Solution Approach 1:
The motor base is divided into central portion and surrounding portion connected by connecting elements. This segmentation allows the central portion to be isolated from vibrations generated by the stator, while the surrounding portion can still accommodate other components. The connecting elements act as vibration isolation barriers, effectively reducing vibration transmission to other components on the motor base.
Solution Approach 2:
Vibration eliminating material is placed between the central portion and surrounding portion of the motor base, serving as an intermediary element. This material absorbs and dampens vibrations before they can propagate to other components, thereby improving vibration elimination effectiveness without significantly complicating the overall structure.
2Ease of manufacture
If vibration eliminating material is assembled after motor base manufacture, then motor base structure is simple, but assembly process becomes complex and time-consuming
Solution Approach 1:
The vibration eliminating material is integrated into the motor base structure during the manufacturing process itself, rather than being assembled separately afterward. This merging of functions allows the motor base to be produced as a single integrated component, simplifying the overall assembly process and reducing manufacturing steps while maintaining structural simplicity.
Solution Approach 2:
The vibration eliminating material is pre-positioned and integrated into the motor base structure before final assembly. This preliminary action ensures that the vibration isolation functionality is built-in from the start, eliminating the need for separate assembly steps and reducing overall assembly complexity and time.
3Object-affected harmful factors
If vibration eliminating material is used, then vibration reduction is attempted, but vibration transmission within motor base structure still occurs
Solution Approach 1:
The motor base is segmented into central and surrounding portions with the vibration eliminating material positioned at the interface. This segmentation creates distinct vibration zones, preventing vibration transmission from the central portion (where the stator is located) to the surrounding portion, thereby improving vibration isolation effectiveness.
Solution Approach 2:
The vibration eliminating material serves as an intermediary layer between the central and surrounding portions of the motor base. This intermediary structure effectively blocks and dampens vibration transmission pathways, preventing vibrations from propagating throughout the entire motor base structure and improving overall vibration isolation performance.
