DC FAN MOTOR
DC FAN MOTOR and AC FAN MOTOR
Cautions For Use
1. Do not reverse-connect the power
supply. Although nothing adverse will
occur if the rated voltage is connected
in reverse for a short time period, the
fan will not operate.
2. If the power is to be pulsed on and
off in order to start and stop the fan
quickly, be sure to install a switch on
the + side of the power supply. Not
doing so may damage the circuit.
3. The DC fan motor installation
bracket has a rib. As shown in the
figure, use the through-bolts when
installing.
4. Use a tightening torque of no more
than 0.6 Nm.

1. Since our fan motor employs
precision ball bearings, due care
should be taken not to apply any
shock in handling.
2. Due to the bearing mechanism, the
noise level will increase in proportion
to the length of time the fan is used.
Avoid use where the temperature is
high or where there is a lot of dirt.
3. Do not allow substances such as oil
and grease to get onto the plastic part
of the fan body. Some oils and greases
decompose and become altered at
high temperatures. These can have an
adverse effect if they contact the fan.
Therefore, be very careful when
handling these substances.
4. Do not apply unnecessary force to
the internal parts when handling the
product. Also, do not use a fan that
has been dropped.
5. Fan life is based on usage at room
temperature and a humidity of 15 to
45% RH. Please verify life under actual
conditions, since life will depend on
the frequency and duration of use, as
well as the atmosphere in which it is
used.
6. Transport and storage conditions
The allowable specifications for
environments suitable for transportation
and storage are given below.
• No freezing between –20°C to 0°C
–4°F to +32°F
• No condensation in the range above
between 0°C to +70°C
+32°F to +158°F
1) Condensation
If the temperature is high and there is a
lot of humidity, condensation will occur
when the temperature suddenly changes.
This should be avoided because it can
cause degradation of the fan insulation.
2) Freezing
At temperatures below 0°C +32°F
moisture such as that caused by
condensation will freeze and lead to
problems such as lockage of the moving
parts and operation lags. Be careful to
prevent this from happening.
3) Low-temperature, low-humidity
environments
Do not leave the fan for a long period in
an environment of low temperature and
low humidity. Doing so may cause the
plastic to become brittle.
4) When storing, avoid places of high
temperature and high humidity or where
corrosive gas is present.
5) Do not store the fan any longer than
six months.
