DC Brushless Blower
Characteristics:
Specications:
Motor design Single phase, 6-poles Brushless DC motor
Insulation Resistance More than 20MΩ between internal stator and
lead wire(+) measured at DC 100V.
Dimensions 12mm × 12mm × 3mm
Dielectric Strength Applied AC 500V for one minute or AC 600V for
2 seconds between housing and lead wire(+)
Noise Level
Measured in a semi-anechoic chamber with
background noise level below 15dB(A). The fan
is running in free air with the microphone at a
distance of one meter from the fan intake.
Input Power, Current &
Speed
Measured after continuous 10 minute opera-
tion at rated voltage in clean air, and at ambient
temperature of 25°C.
Tolerance +20% / -30% on rated power and current.
Air Performance
Measured by a double chamber. The values are
recorded when the fan speed has stabilized at
rated voltage.
Rated voltage 3V DC
Operating Voltage Range 2V DC to 3.5V DC
Starting Voltage 2V DC (25°C power on/off)
Rated Speed 15,500 RPM ±30%
Air Delivery 2.67 L/min
Static Pressure 22.96 Pa
Rated Current 36mA
Rated Power 0.1 Watts
Noise Level 18dB(A) @ 1M
26dB(A) @ 0.3M
Direction of Rotation Counter-clockwise viewed from front of fan blade
Operating Temperature -10°C to +70°C
Storage Temperature -40°C to +70°C
Bearing System Vapo Bearing System
Weight 0.89g
Protection *Automatic Restart
Polarity Protection
* In a situation where the fan is locked by an external force while the electricity is on, an increase in coil temperature will
be prevented by temporarily turning off the electrical power to the motor. The fan will automatically restart when the locked
rotor condition is released.
