Mechanical contactless magnetic levitation high-efficiency
permanent magnet drive intelligent optimised flow field fan
Product Description
Contactless Magnetic Levitation Bearing
Adopting advanced electromagnetic levitation technology, completely
eliminating mechanical contact.
Significantly improves system reliability and service life
Supports high speed rotation, optimising the airflow output of the
fan.
High-efficiency permanent magnet motor drive
Adopts high efficiency, high power density permanent magnet motors
as the drive system.
Higher energy conversion efficiency than conventional induction
motors
Fast response characteristics for quick adjustment of speed and
output
Intelligent optimised 3D flow field design
Advanced numerical simulation and intelligent algorithms are used
to optimise the design of the three-dimensional flow field.
Creates complex vortex airflow patterns, dramatically improving
overall aerodynamic efficiency.
Reduces flow losses and noise and vibration
Directly coupled compact structure
The motor is directly coupled to the impeller, eliminating the need
for a gearbox or belt drive.
Simplified overall structural design and improved transmission
efficiency
Smaller and lighter overall dimensions.
Excellent performance indicators
Ultra-high efficiency: the perfect combination of magnetic
levitation, high-efficiency motors and an optimised flow field
significantly reduces energy consumption.
Outstanding reliability: maintenance-free due to the mechanical
contact-free construction of the maglev and permanent magnet
motors.
High-speed performance: Maglev technology supports higher speeds
and optimised airflow output.
Compact and lightweight: direct coupled design for smaller and
lighter overall dimensions.
Performance Features
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.

core technology
Core Technology with independent intellectual property
right-Magnetic Bearing design and control technology
With independent intellectual property rights of 5 degrees of
freedom magnetic levitation bearing technology, can ensure that
when the equipment is energised, the rotor system can be levitated
by electromagnetic force. The controller ensures more than 10,000
times of signal acquisition per second and gives real-time
correction signals synchronously to ensure the stable levitation of
the high-speed rotor.
With redundant power supply system and protection bearings to
achieve multiple protection, will not cause any damage due to
sudden power failure or fault shutdown.
