Magnetic Bearings
The rotor of the blower is suspended using active magnetic bearings that precisely control the position and levitation of the rotor. These magnetic bearings use electromagnetic coils to generate magnetic fields that counteract the weight and dynamic forces acting on the rotor, keeping it stably suspended without any physical contact. This eliminates mechanical friction and bearing wear, significantly improving the efficiency and reliability of the system.
The magnetic bearing system includes position sensors, control electronics, and a real-time control system that continuously monitors and adjusts the magnetic fields to maintain the rotor in a stable levitated state, even during high-speed operation and under varying load conditions.
Permanent Magnet Motor
The blower is driven by a high-speed permanent magnet (PM) motor. PM motors offer several advantages over traditional induction motors:
The PM motor is directly coupled to the impeller, eliminating the need for a gearbox or belt drive. This simplifies the overall system design and improves power transmission efficiency.
Ternary Flow Impeller
The blower features a ternary flow impeller design, which means the impeller blades have a three-dimensional shape that optimizes the air flow and pressure characteristics. The unique blade geometry creates a complex, swirling flow pattern that reduces losses and improves efficiency compared to conventional impeller designs.
Key benefits of the ternary flow impeller include:
Energy saving and high efficiency
High-speed permanent magnet motor and high-efficiency ternary flow impeller are directly coupled.
More than 30% energy-saving than traditional Roots fan.
More than 20% energy-saving than multi-stage centrifugal blower.
More than 10% energy-saving than single-stage high-speed centrifugal blower.
Low noise
Adopting self-balancing technology, the vibration amount of magnetic levitation bearing is one order of magnitude smaller than that of traditional bearing and no friction. At the same time to take the active damping design, stable operation, body vibration is very small, fan noise at 80dB (A) or so.
Maintenance-free
Integrated design, skid mounted structure, easy installation, one key start and stop. Daily operation, free of mechanical maintenance, only need to replace the filter.
Intelligent control
Adopting PLC+GPRS/3G/4G, it can monitor the running status of the fan in real time, and realise the intelligent regulation of wind volume, wind pressure, rotational speed, etc. as well as manual mode control. In case of failure, it can also be remotely repaired and debugged.
