Maintenance Free: Integrated design, skid mounted structure, convenient installation, one key to start and stop the blower. No need for mechanical maintenance during daily operation, only to replace the filter.
Product Introduction
Magnetic Suspension Centrifugal Blower is a product of high efficiency, energy saving and environmental protection that is directly driven by a high-speed PMSM and a ternary flow centrifugal impeller. The shaft vibration is continuously monitored by a built-in displacement sensor. The collected data will be input to the Magnetic Suspension Bearing Controller for computation to generate the control current. This current will then be supplied to the windings of the Magnetic Suspension Bearing to produce the magnetic force required for levitation.
The PMSM generates frequency-controllable current through an inverter. This current is supplied to the motor stator to create a rotating magnetic field, which drives the shaft to rotate at high speed.
The impeller, driven by the high-speed rotating shaft, draws air in from the volute casing inlet. The air is then accelerated by the impeller and guided by the volute casing, generating flow velocity and pressure. Finally, it is discharged from the volute casing outlet to complete the blowing process.
Active Magnetic Bearing Technology is converted from the magnetic Suspension flywheel technology in the field of space satellite. The high performance attitude control and high efficiency energy conversion of the satellite are realized from magnetic Suspension flywheel technology, which greatly improves the attitude control and operation level of the satellite and effectively solves problems of low efficiency, short service life, routine maintenance requirement and lubrication issues on mechanical support transmission system.
Performance characteristics
Energy Saving and High Efficiency
The ternary flow impeller is directly coupled with a high-speed PMSM, offering significant energy savings:
Saves over 30% energy compared to Roots Blowers
Saves over 20% energy compared to Multi-stage Centrifugal Blowers
Saves over 10% energy compared to Single Stage High-Speed Centrifugal Blowers
Low Noise
With self-balancing technology, the vibration level of the magnetic bearing is lower than that of traditional bearings, and there is no mechanical friction. Thanks to active vibration damping design, the blower operates smoothly with minimal vibration, and noise levels are around 80 dB(A).
Maintenance Free
Featuring an integrated, skid-mounted structure for easy installation, the blower can be started and stopped with a single button. No daily mechanical maintenance is required—only periodic filter replacement.
Intelligent Control
Equipped with PLC and GPRS/3G/4G connectivity, the system enables real-time monitoring of blower status and intelligent or manual control of flow, air pressure, and speed. In case of failure, remote troubleshooting and debugging are also supported.
Core Technology
Core Technology with Independent Intellectual Property Rights——Magnetic Bearing Design and Control Technology
The five-degree-of-freedom magnetic suspension bearing technology, which possesses independent intellectual property rights, ensures that the rotor system is levitated by electromagnetic force when the equipment is powered on. The controller guarantees that signals are collected more than 10,000 times per second, enabling stable suspension of the high-speed rotor.
Redundant power systems and backup bearings provide multiple layers of protection to prevent damage caused by sudden power failures or downtime.
