Description
Technical field
The present invention relates to a kind of application circuit, concrete relate to a kind of stepper motor driving circuit.
Background technology
Stepping motor has in control system widely to be used.It can become angular displacement to the pulse conversion of signals, and can be used as electromagnetic system driving wheel, electromagnetism difference engine or angular displacement generator etc.Existing stepper motor driving circuit is varied of a great variety, but most complex structure, function is complicated; And only need under the application scenario of function singleness at some, adopt the drive circuit of complicated circuit construction to accomplish the motor-driven function of simple function often, cost can increase so on the one hand; In addition on the one hand; After circuit structure was in a single day complicated, its destabilizing factor was behind so just reducing product percent of pass virtually also increasing.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of simple in structure, function admirable, stepper motor driving circuit with low cost.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of stepper motor driving circuit; Comprise an optocoupler, first triode, second triode, the 3rd triode and the 4th triode; First working power connects an input of said optocoupler through first resistance; Incoming level connects the base stage of said first triode through second resistance, and an output of said optocoupler connects second working power through the 3rd resistance, and another output of said optocoupler connects the base stage of said second triode; The emitter of said second triode connects the base stage of said the 3rd triode through the 4th resistance, and the emitter of said the 3rd triode connects the base stage of said the 4th triode.
Further; The grounded emitter of said first triode; The collector electrode of said first triode connects another input of said optocoupler; The collector electrode of said second triode connects said second working power, and first terminals are through the 5th resistance and common capacity earth, and said first terminals connect said the 3rd working power through diode.
The course of work of stepper motor driving circuit of the present invention is following:
When incoming level is a high level; The said first triode conducting, said optocoupler conducting, the said second triode conducting; Said second working power flows to the emitter of said second triode from the collector electrode of said second triode; Launch very high level, said second working power makes said the 3rd triode, the 4th triode conducting through the 4th resistance, and conducting is exported to motor through the 5th resistance later on again.
The present invention has the following advantages:
