Constituent:
The impeller of magnetic suspension centrifugal fan is driven by direct connection between AL7075 impeller and motor. The efficiency of impeller can reach 92% and the service life of impeller can reach more than 20 years. The adjustable range of the fan can reach 45%~100%, and the working range is very wide.

Using the leading ultra-high speed permanent magnet synchronous motor technology, high-speed operation can be realized, and the efficiency of the motor can reach 97.9%. The permanent magnet synchronous motor is equipped with a speed regulating device consisting of a high-performance high-speed real-time digital controller. The system has the advantages of simple control, energy saving, stable speed and low noise. Permanent magnet synchronous motor is mainly characterized by convenient speed regulation, wide speed regulation range, stable operation, low noise and high efficiency. The speed range is large, the service life is much longer than that of traditional motors, and it can meet the speed requirements in various operating modes.

Integrated magnetic suspension bearing, high speed permanent magnet synchronous motor, high efficiency flow parts, special control system and a series of advanced technologies, high efficiency and energy saving of the whole machine.Compared with traditional Roots blower, the efficiency is increased by 30%~40%.Taking 160kW maglev blower as an example, each one can save more than 500,000 degrees of electricity per year compared with the traditional Roots blower, and the cost can be recovered in about 1 to 2 years.

constituent：

impeller：The impeller of the magnetic levitation centrifugal fan is driven by direct connection between the AL7075 impeller and the motor, with an impeller efficiency of up to 92% and a service life of more than 20 years. The frequency conversion adjustment method is used and the guide blade adjustment method is abandoned, so that the adjustable range of the fan can reach 45%6~100%, and the working condition range is very wide.

High-speed permanent magnet synchronous motor:Adopting the leading ultra-high-speed permanent magnet synchronous motor technology, it can achieve high-speed operation, and the efficiency of the motor can reach 97%. The permanent magnet synchronous motor is equipped with a speed regulation device composed of a high-speed real-time digital controller, which is simple to control, energy-saving, stable and low noise. Permanent magnet synchronous motor is mainly manifested in convenient speed regulation, wide speed regulation range, smooth operation, low noise and high efficiency. The speed range is large, and the service life is much higher than that of traditional motors, which can meet the speed requirements in various operating modes.
