For decades, friction and noise have been the root defects for conventional fan motors. Usually after long-term operation, abrasion would be caused by the rub between shaft and inner surface of the bearing, creating noise and sway commonly resulted in many conventional fan motors. Sunon MagLev Motor Fan , the industry-leading fan by Sunonwealth Electric Machine Co., Ltd. since 1999, was created to overcome the defects of traditional fan motors.

Sunon MagLev Motor Fan is the first fan motor to operate without friction between shaft and bearing in the world, and was introduced by Sunon in the fourth quarter of 1999.

The 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 wobbing and shaking problems of general 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. The result is a new and improved fan with a low noise level, high temperature-endurance, and long life.

The MagLev design can be used with sleeve bearings or ball bearings and also works excellent with Sunon's self-innovated - VAPO bearing. Moreover, the inner surface material of Vapo bearing bore is specially treated to enhance the hardness so that the abrasion of shaft can be largely resisted and bearing with high-temp operating environment over 70℃, even among 90℃ to 100℃.

The name MagLev is derived from Magnetic Levitation System. In 2003, Sunon unveils the newly renamed MagLev to more concisely convey the meaning of the product. With MagLev, customers enjoy the high level of precision that comes with this technology, but with a new simplified name.

Since the fourth quarter of 1999, when Sunon first introduced the MagLev Motor Fan, over sixty million units have been shipped to renowned manufacturers all over the world. Substantial contributions have been made by Sunon's MagLev Motor Fans to various industries and products that require high-level heat transfer, such as notebook computers, servers, projectors, and stereo systems.
