Magnetic levitation high-speed centrifugal blower is named because it uses magnetic bearing technology and high-speed motor technology, and integrates the structure of traditional fans. The rotor shaft in themagnetic levitation high-speed centrifugal blower is suspended through the magnetic bearing, which uses the magnetic force to support the rotor shaft and the stator shaft without contact. The built-in displacement sensor monitors the vibration and space clearance of the rotor shaft in real time, and sends the obtained signal to the magnetic bearing controller for conditioning, analysis, budget, and control current generation. Then the current is input into the magnetic bearing to rotate the coil, generating an electromagnetic force, so as to realize the suspension of the rotor shaft. The core of single-stage high-speed centrifugal blower, which is regulated by frequency converter, is magnetic suspension bearing and permanent magnet motor technology.
In the pursuit of energy efficiency and sustainable development, the development of high-speed motors has become the focus of attention in various industries. One of the key components of these machines is the permanent magnet motor, which relies on the use of (NdFeB) or（SmCo）magnets to achieve high performance. The purpose of this paper is to discuss the high efficiency and reliable energy saving secrets and market application value of magnetic levitation blower by using high speed motor and permanent magnet motor. The rotor of the high speed motor is a permanent magnet motor driven by Ndfeb magnets or smco magnets . This type of Ndfeb magnet is known for its high magnetic energy product and high coercivity properties, making it ideal for applications requiring a strong and stable magnetic field. When used in permanent magnet motors, Ndfeb magnets enable motors to operate at high speeds while maintaining high efficiency, making them a key enabler of energy saving solutions.
In the context of magnetic suspension blowers, the use of Ndfeb permanent magnet motors has several advantages. First of all, the high magnetic energy product of Ndfeb magnets allows a strong magnetic field to be generated within the motor, thus achieving efficient and precise control of motor operation. This in turn contributes to the overall energy saving capacity of the blower, as it can achieve the desired air movement with minimal energy consumption. In addition, the high coercive properties of Ndfeb magnets enable them to resist eddy currents that may occur in high-speed motors. Eddy currents are induced currents that can lead to energy loss and reduced motor efficiency. The use of Ndfeb magnets minimizes the eddy current loss of the magnets suspension blower, thereby maximizing its energy saving potential.
In addition to the use of Ndfeb magnets, smco magnets made of permanent magnet motor, the advantage is high temperature resistance, in the case of high-speed operation, as the temperature rises, the temperature requirements of magnets is very challenging, Hangzhou Magnet Power Technology Co., Ltd. in the field of high-speed motor, can produce high temperature smco magnets, the maximum temperature limit of permanent magnet can be extended to 550 degrees Celsius. At the same time, it can produce magnetic steel materials with high magnetic energy product and high coercivity, such as Ndfeb magnets, which can help improve the power density and efficiency of high-speed motors. Hangzhou Magnet Power Technology Co., Ltd. By improving the manufacturing process and materials of magnetsl, reduce the eddy current loss caused by magnets during high-speed rotation, prevent magnetic steel loss and motor heating, so as to ensure the normal operation of the motor, so the development of anti-eddy current magnetic components, by dividing the magnetic steel, bonded with insulating glue, reduce the temperature rise, the conventional laminated adhesive thickness of about 0.08 mm, Our company can do 0.03 mm. In view of the centrifugal force generated by high-speed rotation, the high-speed motor technology manufactured by us also plays a vital role in achieving the energy efficiency of maglev blowers. We have developed effective magnetic steel fixation methods, such as the use of carbon fiber composite materials to fix magnetic steel, using its high tensile strength and stiffness characteristics to ensure that the rotor works safely and stably at high speeds. The rotor design must conform to a motor that can operate at high speeds with minimal energy loss, which requires a high degree of precision and expertise in motor rotor design and development, as well as manufacturing assembly capabilities to ensure seamless integration of motor components. Hangzhou Magnet Power Technology Co., Ltd. has professional rotor design and manufacturing assembly capabilities.
Sewage treatment (municipal, industrial and other) : magnetic levitation high-speed centrifugal blower can be used to aerate the sewage tank, so that the biological active matter in the sewage treatment tank can fully contact the material in the sewage, so as to achieve the purpose of decontamination.
Material conveying (cement factory, chemical industry, food industry, etc.) : magnetic levitation high-speed centrifugal blower can be used in industrial raw materials, dust, food and other pneumatic conveying.
