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 efciency, resulting in energy and cost savings.
Delta’s three-phase fans deliver a variety of advantages:
● High Efciency
● Lower Rotating Vibration
● Optimized Blade Design
● Advanced FET’s /Drivers for lower start up voltage
and ripple current

Data center and server cooling fans demand high energy efciency and low rotating vibration to achieve
thermal requirements and operating performance. Delta three-phase motor brushless DC fans integrate
optimized blade design and advanced electrical drives to achieve high operating efciency (up to 40%) and
low vibration.
The core technologies of Delta’s three-phase brushless DC fans are:
Enhanced Structure
Advanced CAE Analysis in structure design
Three-phase Motor
New motor shape to smooth motor switching
High Efciency Blade
Aerodynamic simulation to smooth airow
