Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a magnetic suspension blower. Background Art

[0002] The magnetic levitation blower is a new type of high-efficiency, energy-saving and environmentally friendly blower that uses core technologies such as magnetic levitation bearings, high-speed permanent magnet synchronous motors and high-efficiency three-dimensional flow impellers. The active magnetic levitation bearing system uses controllable electromagnetic force to provide non-contact and wear-free suspension support for the internal rotor. The position of the rotor is detected by the position sensor and fed back to the magnetic bearing controller. The controller adjusts the magnetic field force of each degree of freedom of the magnetic bearing according to the offset to keep the rotor in the correct position. The high-speed permanent magnet synchronous motor directly drives the three-dimensional flow impeller to rotate at high speed, and the impeller drives the air flow to achieve blowing.
