Solution Overview

Problem

Traditional motor stator structures face challenges in uniformly winding coils on magnetic poles due to stopper sections, which hinder full occupancy of the receiving space and affect magnetization efficiency between the stator and rotor, leading to suboptimal motor performance.

Innovation Solution

The motor stator structure incorporates stopper plates connected to the free ends of magnetic poles, allowing for uniform and full winding of coils without obstruction, enhancing magnetization efficiency by preventing coil dropout and ensuring complete utilization of the receiving space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stopper sections are integrated with magnetic poles, then windings are prevented from dropping out, but the stopper sections hinder the windings from being fully wound in the entire receiving space

Engineering Contradiction:
Improveprevention of winding dropoutVSAvoiduniformity of winding distribution
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The stopper function is segmented from the magnetic pole structure. Stopper plates are separate components that are assembled onto the magnetic poles, allowing the magnetic pole to maintain its full geometry for winding while the stopper plate provides the retention function. This segmentation resolves the conflict between preventing dropout and enabling full winding occupancy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper function is extracted as a separate component (stopper plate) from the magnetic pole structure. The stopper plate is assembled onto the magnetic pole after the winding is completed, allowing the winding to occupy the entire receiving space without being hindered by the stopper structure during the winding process.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If stopper sections are integrated with magnetic poles, then windings are prevented from dropping out, but the windings cannot be uniformly wound on the magnetic poles

Engineering Contradiction:
Improveprevention of winding dropoutVSAvoidmagnetization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By segmenting the stopper function into separate stopper plates, the magnetic pole surface remains uninterrupted and uniform, allowing windings to be evenly distributed. The stopper plates are positioned at the base of the magnetic poles, leaving the winding surface clear for uniform winding operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stopper plates are pre-assembled onto the magnetic poles before the winding process. This preliminary action ensures that the windings can be uniformly wound across the entire receiving space without encountering obstructions, while the stopper plates are already in position to prevent dropout after winding is complete.

Inventive Principle:
Principle #10Preliminary action

3Strength

If stopper sections are integrated with magnetic poles, then structural support is provided, but the stopper sections obstruct the receiving space for windings

Engineering Contradiction:
Improvestructural support of magnetic polesVSAvoidreceiving space for windings
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The stopper plates are positioned in a different dimensional space - at the base of the magnetic poles rather than protruding into the receiving space. This dimensional relocation allows the stopper plates to provide structural support and prevent dropout without obstructing the receiving space where windings need to be wound.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The stopper function is extracted and repositioned to the base of the magnetic poles, separate from the receiving space. The stopper plates are assembled onto the magnetic pole bases, providing structural support and dropout prevention while leaving the receiving space fully available for winding operations.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A motor stator structure includes a main body and multiple stopper plates. The main body has multiple magnetic poles and a shaft hole. The magnetic poles outward extend from the main body. Each magnetic pole has a free end outward extending from the main body. The shaft hole passes through the main body between two ends thereof. The stopper plates are respectively correspondingly assembled with the free ends of the magnetic poles. In the motor stator structure, the windings are more densely wound on the magnetic poles to enhance the magnetization efficiency.
