The magnetic levitation blower is directly driven by a high-speed motor, with speed control provided by an inverter. It utilizes an active magnetic levitation bearing system, which employs controllable electromagnetic force to provide contactless and wear-free support for the internally rotating magnetic levitation bearings. The magnetic levitation bearings are directly connected to the impeller, resulting in zero transmission loss, thus successfully transporting gas while ensuring no wear inside the machine, low noise, and no lubrication required.
The magnetic levitation blower is directly driven by a high-speed motor, with a frequency converter for speed regulation. It utilizes an active magnetic levitation bearing system, providing contactless and wear-free support for the internally rotating magnetic levitation bearings through controllable electromagnetic force. The magnetic levitation bearings are directly connected to the impeller, achieving zero loss in transmission, thus successfully conveying gas with no wear inside the machine, low noise, and no lubrication required.
The function of the magnetic levitation bearing is to achieve the suspension of the rotating shaft. It detects the position signal of the rotating shaft through an internal position sensor, sends this signal to the magnetic levitation bearing controller for conditioning, computation, and amplification to obtain the control current, and then inputs this control current into the magnetic bearing to generate controllable suction on the rotor, thereby achieving the suspension of the rotating shaft.
The function of the synchronous permanent magnet motor is to drive the rotation of the rotor shaft. It generates an adjustable frequency alternating current through a variable frequency power supply, inputs this alternating current into the motor stator to produce a rotating magnetic field, driving the rotor shaft to rotate at high speed.
The function of the blower is to achieve air blowing. The impeller, which rotates at high speed along with the rotor shaft, drives air to enter from the inlet of the volute. Under the guidance and pressurization of the volute, the air becomes a gas with a certain flow rate and pressure, which is finally blown out from the outlet of the volute, thus achieving the air blowing of the blower.
Knowledge expansion of magnetic levitation blowers
It is a mechanical device for conveying gas, utilizing core technologies such as magnetic levitation bearings, tri-flow impellers, high-speed permanent magnet synchronous motors, efficient variable frequency speed regulation, and intelligent monitoring and control. It first levitates and then rotates during startup, with no friction, no lubrication required, and the tri-flow impeller is directly connected to the rotor, achieving zero loss in transmission. It is a high-tech, green, energy-saving, and environmentally friendly product.
The magnetic levitation blower uses contactless, non-mechanical friction magnetic levitation bearings and high-speed, high-power permanent magnet synchronous motors to directly drive efficient fluid impellers, overcoming the disadvantages of traditional blowers and air suspension blowers. It has advantages such as high efficiency, low noise, fewer failures, and no lubrication system required. Even if the magnetic levitation bearing fails, the protective bearing in the system can still safely stop the high-speed rotating rotor without causing serious damage to the equipment.
