The switching drive circuit design of the fan provides the measurement of speed: the fan motor has three wires (red wire: +, black wire: -, yellow wire: the third signal transmission wire)
The company provides the following two signal types
Type R (operation detector)
Type F (square wave generator)
The relationship between rotation and the output pulses of the third wire is as follows according to different products:
(a)1Rotation=2 Pulses(4 poles' motor)
(b)1Rotation=3 Pulses(6 poles' motor)
(c)1Rotation=4 Pulses(8 poles' motor)
remarks:
The normal 8-pole motor should be 1rotation=4 pulses; However, if there is a frequency division circuit design, it will be 1rotation=2pulses after frequency division
