The Sunon patented MagLev design is based on magnetic principles and forces that not only propel the fan but also
ensure stable rotation over its entire 360 degrees of movement. Utilizing the attraction of the magnetic levitation force,
MagLev eliminates the wobbling and shaking problems of traditional motor fans. With this new technology, the MagLev fan
propeller is suspended in air during rotation so that the shaft and bearing do not come into direct contact with each other to
create friction. These features result in a fan with
low acoustic noise level, high-temeperature endurance, and longer
lifespan.
about
Sunon MagLev
SUNON MagLev prevents the defects of conventional fans
Sunon MagLev Solution
Deficiencies of
Traditional Motors
Sleeve Bearing
Ball Bearing
Weight of rotor is entirely loaded on to the
shaft. Abrasive rotation between shaft and
bearing will result in an irregular and rough
surface on the inner surface of bearing bore.
The fan motor rotation becomes uneven and
in turn, causes operational noise and shortens
fan life.
The oil ring and mylar washer not only results
in added friction area but also blocks the
heated air, which, if not released before
solidification, would become nitride particles
that clog up in the gap between shaft and
bearing bore, then causing a much slower
rotation of rotor and noise.
The entire weight of the rotor is
completely attracted by the magnetic
force in any mounted position, keeping
the motor rotating evenly at a fixed point
in a consistent distance from the inner
surface of the bearing. No more
traditional rubs and noise will occur.
The oil rings, the washers are no longer
used in MagLev structure.
For customized use, MagLev design
allows an operating temperature higher
than 700C.
When the fan motor is operating, the steel
balls inside will generate a higher rotational
noise than that of a sleeve bearing.
The construction of Ball bearings is quite
weak and unable to absorb external impact.
The bearings can be easily damaged, causing
louder rotational noise.
Comparison between MagLev and General Motor Fans
2 factors:
the magnet and the stator
The resulting interaction between the maglev
plate and the magnet pulls the rotor downward
along the entire 360-degree surface. Due to the
lower center of gravity, the rotor runs in a more
stable consistent orbit.
The general fan utilizes a deviating magnetic
center to attract the rotor downward. This
technology causes the rotor to vibrate violently,
due to the lack of a consistent orbit as well as a
deviation of the magnetic center.
