Power system:PMSM motor

1. More powerful: 260N.m amazing torque, stronger driving force, smoother torque.

2. More efficient: Unique outer rotor largetorque design,which can control the accuracy with higher precision.

3. More low energy consumption: more than 30% energy-savingthan traditional geared motors, meet IE4 high-efficiency energy-saving standardsand GB30253-2013 national energy efficiency first-level standards. 4. Free maintenance for life: completely sealed, no need toreplace lubricating oil/ oil seal and other accessories, saving a lot of post-maintenaince costs.

5.39 db ultra-low volume, only the sound of wind in your eaars.

6. Lowtemperature-rise: the temperature-rise of the motor is less than35°C, and the life of motor is longer.

Structural connection:Integrated structure connection ensures the overall safety of the fan

1. Blade and petiole connection:The petioles are made of 6061T6 aviation-grade alloy, processed by CNC presion coated wtih polyurethane rubber after CNC precision processed (PU hais high resilience, shock absorption, abrasion resistance, oil resistance, tear resistance, chemical corrosion resistance and radiation resistance), which match the buffer cavity of blade perfectly.It can release the blade stress & airflow vibration efficiently when fan runs, and eliminate resonance, and this helps to reduce the motor load and prolong the motor life.2. Petiole and hub connection:The petiole and the wheel/motor are integrated through the interlocking of the stepped concave-convex section, and the overall structure will withstaand the centrifugal force when the fan runs, while all fasteners are not stressed.3. Motor and flange connection:Anti-falling safety ring: 5 petioles are integrated with the uppercover of the motor to achieve the whole structures will bear the stress.Anti-falling plate: The "concave" section of the flange and the"convex" section of the anti-falling ring are connected under the gravity to ensure thereliable connection between the motor flange and the motor.
