Three-Phase Brushless
DC Motor Fans
Designed for data center and storage servers, Delta’s three-phase brushless DC
motor fans represent the next stage in advancement of server cooling fans.
Three-phase motors provide a stable transition between slots, which allow
fans to run smoothly while maintaining low vibration, high air pressure,
and high energy efficiency, resulting in energy and cost savings.
Delta’s three-phase fans deliver a variety of advantages:
● High Efficiency
●
Lower Rotating Vibration
●
Optimized Blade Design
●
Advanced FET’s /Drivers for lower start up voltage
and ripple current
