Advantage of HVLS Ceiling fan system:
Create constant airflow to reduce perceived temperatures by9-12°C, Reduce energy costs up to 30% by minimizing the
temperature differential from the ceiling to the floor
• Maintains comfort levels throughout building
• Improved employee comfort
• Noise is close to an average library
• Less run time on existing HVAC units.
Advantage of BLDC direct drive Motor:
High Efficiency: up to 83%
Energy saving: 30% saving
Low Noise: 35dBA
Reliability: direct drive, reliable than traditional induction motor/gear box system
Installation Height: lower installation height compare to traditional induction motor/gear box system,can fit low ceiling

Permanent magnet motor for big fan
The new self-developed external rotor motor with large torque and permanent magnet synchronization replaces the traditional
motor+gearbox reducer, achieving a high degree of integration and improving reliability and transmission efficiency.
At the same time, the permanent magnet synchronous external rotor motor is adopted, with its own IMU configuration, to achieve the
ESC active control strategy+coordinated regenerative braking strategy, driven by the motor directly; Any torque recovery or
auxili-ary braking within the peak torque can be satisfied.
Aluminium alloy material is adopted in many parts to realize the lightweight design.
