Problem
Permanent-magnet synchronous motors, particularly axial magnetic field types, require complex and time-consuming maintenance due to the need for entire stator replacement when issues arise, such as stator problems, making service operations cumbersome.
Innovation Solution
A motor stator assembly design featuring a stator base with a receiving space and positioning holes for coil assemblies, allowing for easy embedding and removal of coil assemblies, along with positioning rings to secure them in place, facilitating convenient maintenance and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire stator is replaced when there is a problem with the stator, then the motor can be repaired, but the maintenance process is complicated and time-consuming
Solution Approach 1:
The stator is divided into independent modular components: stator base, coil assemblies, and positioning rings. Each coil assembly can be independently removed and replaced through positioning holes in the stator base, eliminating the need to replace the entire stator when only coils are faulty. This modular segmentation directly reduces maintenance complexity while preserving motor repairability.
Solution Approach 2:
The coil assemblies are extracted as separate removable components from the stator structure. Through positioning holes and positioning rings, coil assemblies can be individually taken out and replaced without affecting other stator components. This extraction principle enables selective replacement of only the faulty parts, significantly simplifying the repair process.
2Reliability
If the entire stator is replaced when there is a problem with the stator, then the motor can be repaired, but the maintenance time is long
Solution Approach 1:
The stator is divided into independent modular components: stator base, coil assemblies, and positioning rings. Each coil assembly can be independently removed and replaced through positioning holes in the stator base, eliminating the need to replace the entire stator when only coils are faulty. This modular segmentation directly reduces maintenance complexity while preserving motor repairability.
Solution Approach 2:
Positioning holes and positioning rings are pre-designed into the stator structure to facilitate quick coil assembly installation and removal. This preliminary structural preparation enables rapid maintenance operations without requiring complex assembly procedures, significantly reducing maintenance time while ensuring proper component alignment.
3Volume of moving object
If coil assemblies are inserted in the receiving space, then the stator structure is compact, but the coil assemblies need to be securely positioned
Solution Approach 1:
Positioning rings act as intermediary components between the coil assemblies and the stator base. These rings are installed in positioning holes and provide mechanical constraint to secure coil assemblies in the receiving space. The positioning rings mediate the connection, ensuring stable coil positioning while maintaining the compact stator structure designed for space efficiency.
