The magnetic levitation blower uses magnetic levitation bearing technology, which is based on the principle of magnetic force to achieve bearing support and rotational motion. The following is the working principle of magnetic levitation bearings:
1. Active magnetic bearing: Active magnetic bearing is composed of an electromagnetic coil and a control system. An electromagnetic coil generates a magnetic field through current, and when there is an interaction between the magnetic field and the rotor, it can achieve load-bearing and levitation functions. The control system adjusts the force of the magnetic field by measuring and monitoring the position and speed of the rotor, and controlling the changes in current according to the preset working mode and control algorithm, thereby maintaining the stable suspension of the rotor during the rotation process.
2. Passive magnetic bearings: Passive magnetic bearings are usually composed of permanent magnets and iron cores. A permanent magnet generates a constant magnetic field, while an iron core is used to guide the magnetic force. When the rotor leaves the axis position, the passive magnetic bearing will generate magnetic force deviation, causing the rotor to return to the axis position.
By using magnetic levitation bearing technology, the magnetic levitation blower can achieve contactless and frictionless operation, reduce energy consumption and vibration noise, and extend the service life of the equipment. In addition, magnetic levitation bearings also have the advantages of instantaneous start, fast response, and high speed, and are widely used in industrial fields that require high-precision, high-power transmission, and lubrication free requirements.
