Motor Mounting Bracket With Multiple Interface Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing system requires a unique mounting bracket for each stator frame size, resulting in a large number of bracket articles and complexity in achieving standardized shaft heights for electrical motors with different frame sizes.
Innovation Solution
A mounting bracket design that combines two or more unique interfaces at different distances from the bottom surface, allowing a single bracket to support multiple stator frame sizes and maintain equal shaft height, thereby reducing the number of bracket articles needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a unique mounting bracket is used for each stator frame size, then the correct shaft height and hole pattern are achieved, but the number of mounting bracket articles becomes large
Solution Approach 1:
The mounting bracket is designed with multiple mounting interfaces that can accommodate different stator frame sizes. Each interface has a specific distance from the bottom surface, allowing a single bracket design to serve multiple functions across different motor frame sizes while maintaining standardized shaft heights and hole patterns.
Solution Approach 2:
Different regions of the mounting bracket have different properties - specifically, the mounting interfaces are positioned at different distances from the bottom surface. This local variation in geometry allows the bracket to adapt to different stator frame sizes while maintaining overall structural integrity and functional consistency.
2Manufacturing precision
If different sizes of mounting brackets are used for different stator frame sizes, then the correct shaft height is achieved, but the device complexity increases
Solution Approach 1:
Instead of creating multiple unique bracket designs for different stator frame sizes, a single universal mounting bracket design is used with multiple mounting interfaces. This reduces device complexity by eliminating the need to manage multiple bracket variants while still achieving the correct shaft height for each configuration.
Solution Approach 2:
The mounting bracket is segmented into multiple mounting interfaces, each optimized for a specific stator frame size. This segmentation allows the single bracket to handle multiple configurations without increasing overall design complexity, as each interface is a distinct, manageable feature.
3Reliability
If multiple unique mounting bracket designs are maintained, then each stator frame size has a corresponding correct bracket, but the number of mounting bracket articles becomes large
Solution Approach 1:
The mounting bracket incorporates multiple mounting interfaces within a single design, allowing it to provide the correct hole pattern for different stator frame sizes. This ensures reliability of the hole pattern positioning while reducing the total number of bracket articles needed in inventory.
