Integrated Coil Guide Motor Layout Without Bus Bar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motors face challenges in reducing the number of fusing processes, parts, and size, particularly when connected to vehicle components like braking devices, where the length of the worm shaft and diameter of the worm wheel necessitate a larger motor size.
Innovation Solution
The motor design incorporates an annular body with protruding coil guides and a terminal cover that eliminates the need for a bus bar assembly by directly guiding coils to terminals, reducing the number of components and fusing points, and simplifying the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bus bar assembly with multiple fusing processes is used to connect coils to terminals, then reliable electrical connection is achieved, but the number of manufacturing processes and parts increases
Solution Approach 1:
The patent merges the bus bar assembly with the terminal cover by integrating the terminal directly into the terminal cover structure. This eliminates the separate bus bar component and reduces the number of fusing processes, while maintaining reliable electrical connection between the coil and terminal through the integrated design.
2Adaptability or versatility
If a worm shaft and worm wheel are added to transmit rotational force vertically, then power transmission function is achieved, but the motor size increases
Solution Approach 1:
The terminal cover is designed to serve multiple functions: it provides structural support, houses the terminal for electrical connection, and integrates the power transmission interface. By making the terminal cover multi-functional, the patent eliminates the need for separate worm shaft and worm wheel components, reducing motor size while maintaining power transmission capability.
