Magnetic Levitation Fan: Performance Characteristics and Selection of Magnetic Levitation Fans
Release date:
2021-09-06
Let me briefly introduce the performance characteristics of magnetic levitation fans and how to choose the right fan for your needs. Magnetic levitation fans employ non-contact magnetic levitation bearings that eliminate mechanical friction, along with high-speed, high-power permanent-magnet synchronous motors, which directly drive highly efficient fluid impellers. This design overcomes the shortcomings of conventional blowers and traditional magnetic levitation blowers, offering advantages such as high efficiency, low noise, fewer failures, and no need for a lubrication system—even in the event of a failure in the magnetic levitation bearings.
Let me give everyone a quick overview. Magnetic levitation fan Performance Characteristics and Fan Selection
Performance characteristics of magnetic levitation fans
The magnetic levitation fan employs non-contact magnetic levitation bearings that eliminate mechanical friction, along with a high-speed, high-power permanent-magnet synchronous motor, directly driving a highly efficient fluid impeller. This design overcomes the drawbacks of conventional blowers and magnetic levitation blowers, offering advantages such as high efficiency, low noise, fewer failures, and no need for a lubrication system—even in the event of a failure in the magnetic levitation bearings.
1. Magnetic levitation fans are energy-efficient and highly efficient. The magnetic levitation centrifugal blowers employ magnetic levitation bearings that eliminate mechanical and contact losses, enabling stepless speed regulation at high rotational speeds.
2. The magnetic levitation fan boasts high cooling efficiency. Its cooling system employs a combination of water-cooling and air-cooling methods, effectively protecting the motor and meeting the requirement for the fan to start and stop at any time.
3. Magnetic levitation fans feature low noise levels and easy installation. Thanks to their box-type structure, these fans produce noise below 80 decibels, with minimal vibration. They have low requirements for the installation foundation and are very convenient to install. Currently, the maximum rotational speed of magnetic levitation centrifugal blowers has reached 40,000 rpm, allowing them to operate reliably and stably within their working range. Their vibration and noise levels are lower than those of other types of centrifugal blowers that use mechanical bearings.
However, magnetic levitation requires highly sophisticated control systems and sensors to accurately monitor the “poles of the magnets.” Moreover, since bearing performance can fail, auxiliary measures—such as batteries or auxiliary bearings lubricated with oil—are necessary. When bearing connections fail, maintenance costs tend to rise significantly.
Magnetic levitation fan The choice
1. The power rating of an electric motor generally refers to its rated power—the maximum power at which the motor can operate normally under its rated voltage. Moreover, when the motor is operated at the rated values specified by the manufacturer, the power output at the motor’s shaft is expressed in kilowatts (kW). All linear motor vehicles are controlled by variable-frequency control cabinets; therefore, the air volume typically falls within a certain range. Motor power is a key parameter that needs to be considered when selecting a linear motor vehicle. If the equipment is being retrofitted, you can first provide the previous motor’s power rating, which we can use as a reference during selection. Once we have obtained the motor’s output power, we can roughly determine the appropriate range for the fan.
2. Airflow and static pressure are important parameters for selecting a magnetic levitation blower. When the airflow and blower capacity meet the requirements of the application, you can choose more energy-efficient equipment. During later operation, you can use the PLC control panel to regulate the airflow and static pressure within a specified range.
