Outer Rotor Motor End Cap Wire Routing Trough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for distributing wiring in outer rotor motors are time-consuming, expensive, and prone to errors, leading to potential damage and malfunctions due to looseness and displacement.
Innovation Solution
The implementation of a wire-routing trough structure within the stator core that defines a wiring pathway, positioned radially inside the core, with a bottom between core margins and sides projecting axially, facilitating efficient, accurate, and protected wiring distribution, and a stator mount located within the wiring pathway to minimize obstructions and reduce motor size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional wiring distribution techniques are used, then wiring can be installed, but the process is time-consuming and expensive
Solution Approach 1:
The wire-routing trough is pre-formed as an integral part of the stator core structure, creating the wiring pathway before the wiring installation process begins. This preliminary preparation of the routing path eliminates the need for time-consuming on-site wiring distribution work, allowing wires to be simply placed into the pre-defined trough.
2Reliability
If conventional wiring distribution techniques are used, then wiring can be installed, but errors and damage are prone to occur
Solution Approach 1:
The wire-routing trough acts as a protective channel that confines and secures the wiring within the stator core structure. The trough prevents wires from being damaged by external forces and eliminates wire loosening and displacement by providing a dedicated routing path that holds the wiring in place throughout operation.
3Reliability
If wiring is routed without a dedicated pathway, then space is available, but wiring protection and organization are compromised
Solution Approach 1:
The wire-routing trough is merged with the stator core as an integral structural feature rather than a separate component. This integration allows the wiring pathway to be formed within the existing motor volume without adding external wiring channels or protective structures, thus providing wiring protection while maintaining a compact motor envelope.
4Volume of moving object
If a stator mount is placed within the wiring pathway, then space utilization is improved, but wiring routing complexity increases
Solution Approach 1:
The wire-routing trough is designed with segmented or divided sections that allow the stator mount to be positioned within the overall wiring pathway area. The trough structure is partitioned to provide separate routing channels or spaces that accommodate both the stator mount and the wiring, eliminating interference between these components while maximizing space utilization.

AI summary
An outer rotor motor includes a stator, an end cap for use with the stator, and a stator mount operable to facilitate mounting of the stator to a machine. The end cap includes wire-routing structure facilitating routing of the stator wiring. The structure includes a wire-routing trough that defines a wiring pathway though which the wiring is routed. The trough is positioned at least in part radially inside the core and includes a bottom located between the core margins. The trough further includes a side that is spaced radially inward from the core and projects at least in part axially relative to the bottom. The stator mount is radially located within the wiring pathway.
