Concrete principle is analyzed as follows：The forward voltage drop of diode is have ignored in analysis.Vin is a low-voltage ac signal
Source, the signal source can be produced by a simple Industrial Frequency Transformer.Vin waveforms, as shown in Figure 2.
Vin signals are connected to the analysis between T1 the and COM pin in Fig. 1
When Vin is less than voltage-stabiliser tube D2 voltage stabilizing value in positive half cycle and Vin voltages, optocoupler U1 shut-offs, the high electricity of Out ends output
It is flat.As Vin voltages raise, when reaching t1 moment points, when its magnitude of voltage is higher than voltage-stabiliser tube D2 voltage stabilizing value, optocoupler U1 is opened
It is logical, Out ends output low level.T2 moment points, voltage stabilizing values of the Vin again below voltage-stabiliser tube D2, optocoupler U1 shut-offs, Out ends are arrived
Export high level.When Vin is in negative half period, because diode D1 one-way conduction limits, optocoupler U1 is turned off always, and Out ends are defeated
Go out high level.Such case Out ends output waveform is as shown in Vout1 in Fig. 2.
Vin signals are connected to the analysis between T2 the and COM pin in Fig. 1
When Vin is less than voltage-stabiliser tube D2 voltage stabilizing value in positive half cycle and Vin voltages, the shut-off of optocoupler U1 sides, the output of Out ends is high
Level.As Vin voltages raise, when reaching t1 moment points, when its magnitude of voltage is higher than voltage-stabiliser tube D2 voltage stabilizing value, optocoupler U1 is opened
It is logical, Out ends output low level.T2 moment points, voltage stabilizing values of the Vin again below voltage-stabiliser tube D2, optocoupler U1 shut-offs, Out ends are arrived
Export high level.When Vin is in negative half period, t3 moment points are arrived, Vin backward voltages are more than voltage-stabiliser tube D3 voltage stabilizing value, optocoupler
It is open-minded, Out ends output low level.T4 moment points have been arrived, Vin backward voltages are less than voltage-stabiliser tube D3 voltage stabilizing value, and optocoupler turns off,
Out ends export high level.Such case Out ends output waveform is as shown in Vout2 in Fig. 2.
Vout1 and Vout2 waveforms in analysis chart 2, it can be found that the frequency of Vout1 waveform is the 2 of Vin waveform frequencies
Times, the frequency of Vout2 waveforms is equal to Vin waveform frequencies.Therefore, the frequency of Out ends output waveform is detected it is known that Vin believes
Number it is which input enters from T1/T2, then DC brushless motor carrys out setting speed accordingly.
Detection circuit in one Fig. 1 can realize two grades of controls.Detection circuit in using two Fig. 1 can be realized
Fourth gear controls.The detection circuit that can be superimposed according to the actual requirements in multiple Fig. 1, finally realize the multipolar dynamo control of any gear
Input speed governing.
