Customer Background
Foxconn, a global top-tier electronics manufacturing service provider, produces high-end air purifiers for European medical equipment brands. Products require EN 13485 certification with noise levels <28dB(A).
Pain Points
Medical-grade quiet standard: Fan drive must avoid 2-5kHz human-sensitive frequency band
Dual EMC certifications: EN 55011 (Industrial) & EN 60601 (Medical)
Zero-defect delivery: First-batch defect rate <0.1%
Hunovate Solution
✓ Core Technologies
Sensorless sinusoidal FOC drive (dynamic carrier frequency adjustment)
Four-fold protection: Phase-loss/Over-current/Over-voltage/Under-voltage
GAN devices reduce switching noise
✓ EMC Design
π-filter + magnetic ring common-mode suppression (EN 60601-1-2 certified)
✓ Reliability
85℃/85%RH accelerated aging for 1500 hours
