Windability Tester
-Test your wires durability and mechanical performances before winding
A windability test evaluates the mechanical performance and durability of enamelled wire during winding processes, ensuring the enamel insulation remains intact under stress like stretching, abrasion, and twisting. These tests simulate real-world coil manufacturing conditions to prevent failures such as enamel cracking, peeling, or shorts.
Key Test Methods
Common windability assessments include NEMA windability tests, where wire is wound multiple strokes around a mandrel to check for insulation breakdown, and repeated scrape or abrasion tests measuring resistance to wear. Flexibility tests like round rod winding involve wrapping wire around rods of specified diameters to detect enamel cracks after a specific number of turns.
Purpose and Parameters
These tests verify enamel adhesion, elongation, and scratch resistance, critical for high-speed winding without defects growing into short cuts. Poor windability can lead to layer short cuts or coil failures, so metrics like stroke count, twist numbers before peeling, and abrasion load are quantified.
