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)
(c) 1 Rotation=4 Pulses(8 poles' motor)
Notice:
For 8 poles' motor: normally,
1Rotation=4 pulses, if frequency divided
circuit is implemented in this motor then
1Rotation=2 pulses.
