award 3

Residual intermal temperature is lower; hence, the life span of the motor is
Wires with thicker diameter can be used. The torque of the motor is increased by
It is possible to design thinner, smaller cooling fans。
The motor center area is reduced while the impeller size is increased. More airflow
can be expected with a larger impeller。
The cooling fan can be operated under high ambient temperature(90℃)。
The power consumption is lowered to meet environmental requirements。
Electronic components are replaced by Driver Ics. This reduces soldering points and
hence the production process is simplified. Moreover, failure-rates are reduced。
Extra Small and Thin Motor
The patented design of SUMON fan motor, featuring a single coil, allows us to reduce the hub of the motor. When the core of motor bceomes smaller, the fan's impeller becomes relatively longer and bigger. Thus, the air flow is increased accordingly, Powered by this patented motor, every SUNON/s miniature cooling fan and blower provides 40% more air flow than other fans and blowers at the market. A SUNON's fan with lower RPM than competitors provides the same air flow. As a reault, it has a Quieter operation than others.
Very Low Starting Voltage
At current market, the so-called low starting voltage is at 4 VDC. However, SUNON's super low starting voltage is at 2.8 VDC for 5 VDC type. This type of low starting voltage is designed especially for Notebook PC.
As known, Notebook PCs generally have limitation of power supply and cabinet space. SUNON's 5 VDC fan can be started up at 2.8VDC and then the voltage increases up to VDC for full speed as needed. This design substantially conserves power consumption and thus prolongs the source of power as well as operating of the fan.
Super Low Electric Current
SUNON's patented motor design increases the mumber of pole to 8 or more. SUNON's 8-pole motor consumes only 40% less electric power than others do at the market. An 8-pole motor produces higher torque than a 4-pole one does. Therefore, with the application of SUNON's miniature cooling fan and blower, an electronic device not only has low power consumption and high cooling efficiency, but also a prolonged operating life.
