Stator Pole Winding With Linear Nozzle Motion for Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing winding methods for wire rods around magnetic poles in stator cores result in varying tension, making it difficult to achieve alignment and improve the space factor of the wire rod.
Innovation Solution
A winding method that combines the swinging of magnetic poles with the relative movement of a nozzle in the axial direction of the stator core, while moving the nozzle linearly in the radial direction to maintain a linear relative movement with respect to the magnetic pole, thereby ensuring consistent tension and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stator core is rotated to wind the wire rod around magnetic poles, then the wire rod can be wound around the magnetic poles, but the tip end of the nozzle undergoes arc-like relative movement with respect to the magnetic pole causing tension variation
Solution Approach 1:
The patent applies dynamics by making the nozzle movable in the radial direction of the stator core while the magnetic pole is being swung. This dynamic adjustment allows the nozzle to compensate for the arc-like movement, maintaining linear relative movement with respect to the magnetic pole width direction and ensuring consistent wire rod tension during winding
Solution Approach 2:
The patent changes the movement parameter of the nozzle from static to dynamic by moving it in the radial direction during the swinging process. This parameter change transforms the relative movement trajectory from arc-shaped to linear, resolving the tension variation issue while maintaining winding capability
2Ease of operation
If the nozzle is moved in the axial direction to revolve around the magnetic pole, then the wire rod can be delivered to the magnetic pole, but the arc-shaped pattern formation causes tension variation
Solution Approach 1:
The patent makes the nozzle dynamically adjustable in the radial direction during the winding operation. This dynamic movement allows the nozzle to maintain a linear relative trajectory with respect to the magnetic pole width direction, eliminating arc-shaped pattern formation and ensuring consistent wire rod tension throughout the winding process

AI summary
A winding method of a wire rod includes a step of winding the wire rod (12) delivered from a tip end of a nozzle (11) around magnetic poles (13b, 63b) by revolving the tip end of the nozzle (11) around a magnetic pole (13b, 63b) of the magnetic poles (13b, 63b) by combining swinging of the magnetic pole (13b, 63b) about a center axis (O) of a stator core (13, 63) and a relative movement of the nozzle (11) in an axial direction of the stator core (13, 63) with respect to a slot (13c, 63c) between the magnetic poles (13b, 63b), wherein by moving the nozzle (11) in a radial direction of the stator core (13, 63) while the magnetic pole (13b, 63b) is being swung, the tip end of the nozzle (11) from which the wire rod (12) is delivered is moved linearly relative to a width direction of the magnetic pole (13b, 63b).
