Active Magnetic Bearing (AMB) Blower

Energy savings of over 30% compared to traditional Roots or multi-stage centrifugal blowers.

The Maglev Blower is a highly integrated, energy-saving industrial solution. By utilizing an active magnetic bearing system, the rotor is fully levitated during operation, completely eliminating mechanical friction. Integrating high-speed permanent magnet motors, high-efficiency ternary impellers, and intelligent control systems, it is the premier power source for achieving low-carbon and smart upgrades in industrial processes.

Features and Benefits

Energy-Efficient: Incorporating a direct-drive permanent magnet motor and tri-dimensional flow impeller technology, it achieves a significant reduction in energy consumption—ranging from 20% to 30%—compared to traditional blowers.
Environmentally Friendly: Featuring an oil-free, friction-free design and ultra-low operating noise levels, it delivers a clean air supply while allowing for flexible deployment in various office or residential environments.
Superior Operational Performance: The system requires absolutely no lubrication, and the main unit is maintenance-free; combined with an exceptionally long service life, this significantly reduces long-term operational and maintenance costs, as well as production-related risks.
Power-Loss Safety: A built-in UPS power system provides real-time protection against power outages, ensuring the equipment can safely decelerate to a smooth, controlled shutdown in the event of a power failure.
Intelligent Control & Management: Supports remote monitoring, operation, and maintenance capabilities, enabling precise regulation of operational parameters and comprehensive historical data logging.

Working Principle

The blower's permanent magnet synchronous motor drives a three-dimensional flow impeller to rotate at high speed. As the impeller spins rapidly, the gas within it rotates in tandem and is flung outward under the influence of centrifugal force; subsequently, it undergoes diffusion within the volute casing to form pressurized gas. Simultaneously, a vacuum zone is created at the impeller inlet, allowing fresh external gas to continuously flow into the impeller, thereby establishing a continuous flow of gas.

Magnetic Levitation Blower vs. Air-Bearing Blower

Feature	Air Bearing Blower	Maglev Blower
Start/Stop Cycles	Limited: Friction occurs at low speeds; coating wears out, leading to rotor seizure.	Unlimited: Levitation before rotation; remains levitated until static.
Cleanliness	High: Micro-level (μm) gap requirements.	Lower: Millimeter-level (mm) gap between rotor/stator.
Load Capacity	Small: Max system power ~200kW.	Large: Power up to 1000kW+; rotor weight up to 2650kg.
