By modelling the complex interactions between assembly parameters, designers can identify optimal configurations that minimize insulation paper damage during stator winding production.

IEEE Access · 2020

Key Findings

01An additive model alone is insufficient to predict insulation damage due to high parameter correlation.
02An extended additive model, including a virtual parameter to represent interparameter influences, accurately predicts optimal assembly configurations.
03The developed model identifies parameter settings that prevent degradation of insulation paper breakdown voltage.

Application

Design takeaway

In complex manufacturing assembly, move beyond simple additive models and investigate how different parameters interact to predict and prevent defects.

How to apply

When designing or optimizing an assembly process, use statistical modelling techniques like Design of Experiments to identify and quantify the interactions between critical parameters, rather than treating them in isolation.

Project actions

01Consider how different design choices might interact with each other, not just their individual effects.
02Use statistical tools to analyze your findings, especially if you have multiple variables.

Method & Evidence

AimTo develop a predictive model for insulation paper damage in stator winding assembly that accounts for interdependencies between key assembly parameters.

MethodDesign of Experiments (DOE) with an extended additive model incorporating virtual parameters to capture interaction effects.

ProcedureExperiments were designed using an orthogonal matrix to systematically vary magnet wire thickness, stator slot smoothness, magnet wire length, and insulation cap type/amount. Insulation paper breakdown voltage was measured before and after assembly/disassembly to quantify damage. An extended additive model was developed and validated.

ContextManufacturing of stator windings for electromagnetic coils.

Variables

IV["Magnet wire thickness","Stator slot smoothness","Length of the straight magnet wire after the slot end","Type and amount of insulation cap"]

DV["Decrease of insulation paper breakdown voltage"]

CV["Assembly/disassembly process","Measurement of breakdown voltage"]

Strengths & Limitations

Strengths

+Systematic approach using Design of Experiments.
+Inclusion of interaction effects in the modelling, leading to a more accurate predictive model.

Limitations

The complexity of the modelling approach might be challenging to implement without specialized software or statistical knowledge. The 'virtual parameter' is an abstract concept.

Reliability & validity

Reliability was addressed through repetition of experiments. Validity is supported by the development of a model that accurately predicts outcomes and is verified by control experiments.

Think critically

How might the 'virtual parameter' used in this study be conceptualized or represented in a physical design context, rather than purely as a mathematical construct?

Design Principles

"Model parameter interactions to optimize manufacturing processes and minimize product defects."

This research highlights the critical need for sophisticated modelling in manufacturing processes where subtle variations can lead to significant product defects. Understanding these interdependencies allows for proactive design adjustments, preventing costly rework and improving product reliability.

What This Means for Your Design

When putting things together in a factory, sometimes changing one part affects how another part works. This study shows how to use math to figure out those connections so you don't damage the insulation on wires.

This research by Stefe and Jenko (2020) demonstrates the critical need to model parameter interactions in manufacturing assembly. Their work on stator winding highlighted that additive models were insufficient, necessitating an extended model to account for interdependencies, leading to optimized configurations that prevented insulation damage. This underscores the importance of considering synergistic effects when designing and refining production processes to ensure product integrity.
