Working principle of magnetic levitation blower

The magnetic levitation blower is directly driven by a high-speed motor, and the speed is adjusted by a frequency converter. The active magnetic levitation bearing system is used to provide non-contact and wear-free levitation support for the internal rotating magnetic levitation bearing through controllable electromagnetic force. The magnetic levitation bearing is directly connected to the impeller. Transmission zero loss, in order to achieve the successful delivery of gas without wear inside the machine, low noise, no lubrication and other effects.

The function of the magnetic suspension bearing is to realize the suspension of the rotating shaft. It detects the position signal of the rotating shaft through the built-in position sensor, sends this signal to the magnetic suspension bearing controller for conditioning, calculation and amplification to obtain the control current, and then inputs the control current to the magnetic bearing to generate a controllable suction force on the rotor. Suspension of the shaft.

The function of the synchronous permanent magnet motor is to drive the rotation of the rotor shaft. It generates frequency-adjustable alternating current through a variable frequency power supply, and the alternating current is input into the motor stator to generate a rotating magnetic field, which drives the rotating shaft to rotate at high speed.

The function of the blower fan is to realize blasting. The impeller rotating at high speed along with the rotating shaft drives the air to enter from the inlet of the volute, and the air becomes a gas with a certain flow rate and pressure under the guidance and pressurization of the volute, and finally bulges out from the outlet of the volute. Just realized the air blowing of blower fan.
