Ensure insulation reliability with impulse winding testers, partial discharge detectors, and integrated QA systems – trusted for EV and industrial motor applications.
Why Motor Coil QA Matters
EV and industrial motors demand high insulation reliability.
Motor coil testing detects insulation weaknesses early, preventing failures and ensuring safety and performance.
❗ Problem – Coil Insulation Failures
Voltage surges, thermal stress, and aging lead to insulation breakdown.
✅ Solution – Advanced Motor Coil Testing
Impulse and partial discharge testing detect defects before failure.
→ Detect weak coil insulation
→ Identify early-stage degradation
→ Complete testing for armature & stator
