The Nova 2000 Windability Tester performs a unique toughness test on magnet wire. The magnet wire is anchored
between two directional wire mounting clamps under tension. The wire between the two clamps is then passed
through the mandrel/high voltage guide sheaves assembly. The wire is then wrapped once around the mandrel. The
mandrel is located between two sets of high voltage guide sheaves. When the test starts, the mandrel/high voltage
guide sheaves assembly moves from one end of the tester to the opposite end repeatedly until the magnet wire fails.
The wire around the mandrel is stretched and the cross section (diameter) of the wire decreases. During the test, the
insulation experience abrasion, flexibility, adhesion failure, etc. When the insulation fails, the fault detection circuit
detects the faults. When 3 faults are detected, the numbers of stroke are counted. Low stroke count indicates the
enamel is under-cured or over-cured, presence of pinholes, low toughness, etc. High strokes count indicates insulation
that is correctly cured with good toughness, abrasion resistance, flexibility, lubricity and adhesion.
