Advantages

1.Motor drive rate is greatly improved

The permanent magnet synchronous motor has a small current, and the stator copper consumption of the motor is smaller, so the efficiency is higher than that of the asynchronous motor, and the transmission rate is also higher. The motor efficiency of common asynchronous motors is 78%, the motor efficiency of the super-wing series PMSM motors is 86%, and the transmission efficiency of the entire motor is increased by 13.6%.

2.Adjustable speed range is larger

At present, the market has a common 7.3M diameter and fan blade type, the speed range is usually 20-50RPM, while the super wing series, based on the powerful PMSM power output system and control technology, the stepless speed range is extended to 10-52RPM, providing you with a wider range of comfort adjustments.

3.Low noise and ultra quiet

The Super-wing series uses the latest PMSM technology to reduce noise to 38.5db for the first time, truly low noise. The noise of the asynchronous motor deceleration machine mainly comes from the excitation noise of the motor casing and the friction of the gear of the reducer. The noise standard is usually about 45-50dBA.

4.Powerful wind ,big air volume

The super-wing series adopts the latest PMSM technology, low-speed high-torque drive motor, which can meet any torque recovery or auxiliary braking within the peak torque, eliminating the friction energy consumption of the gear reducer, and the maximum torque reaches 300N.m. The most powerful advantage of the Superwing series is its air volume, which reached 528,675CFM at full load, surpassing the market’s common product air volume by 30%, which has been unanimously recognized by customers and highly evaluated by the marke.

5.Thermal design

Efficient cooling system (heat dissipation surface area up to 2.16㎡), perfect solution to the contradiction between performance and heat in PMSM technology.

In the heat dissipation system, through the two methods of contact heat dissipation and radiation heat dissipation, the ingenious structural design selects the high-density alloy aluminum material of the high heat conduction system to achieve the perfect heat dissipation effect and ensure the longer life characteristics of the motor.
