Description

Technical Field

[0002] The magnetic levitation blower is a mechanical device for conveying gas. It utilizes core technologies such as magnetic bearings, a three-dimensional flow impeller, a high-speed permanent magnet synchronous motor, efficient inverter speed regulation, and intelligent monitoring and control. During startup, the blower first levitates and then rotates, creating a frictionless, lubrication-free system. The three-dimensional flow impeller is directly connected to the rotor, resulting in zero transmission losses. This high-tech, green, energy-saving, and environmentally friendly product is a result. The magnetic levitation blower utilizes contactless, frictionless magnetic bearings and a high-speed, high-power permanent magnet synchronous motor to directly drive the high-efficiency fluid impeller. This overcomes the shortcomings of traditional blowers and air suspension blowers, offering advantages such as high efficiency, low noise, minimal malfunctions, and the absence of a lubrication system.
