Fan 3rd Wire Signal

Safety

Certification

Fan with switching driving circuit designed for rpm

measurement:

These fan motors have three lead wires:

+:Red,

-:Black,

output signal for 3rd wire:

F Type : Yellow

R Type : White

The relationship between rotation & output

pulses signal from 3rd wire are as follows:

(a) 1 Rotation=2 Pulses(4 poles' motor)

(b) 1 Rotation=3 Pulses(6 poles' motor)

Notice:

For 8 poles' motor: normally,

1Rotation=4 pulses, if frequency divided

circuit is implemented in this motor then

1Rotation=2 pulses.
