Description
Technical field:
The utility model relates to technical field of motors, more specifically to a kind of motor control assembly based on 555 timers.
Background technology:
The design of existing electric machine controller is general comparatively complicated, and production cost is higher, and it is also convenient not to assemble, and haves much room for improvement.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of simple motor controller, and its circuit structure is simple, and production cost is low, easy to assembly, can be widely used in the continuous running such as track, streamline equipment and carry out Electric Machine Control; It can reach by regulating the resistance of adjustable resistance the object regulating motor speed.
Technology solution of the present utility model is as follows:
Simple motor controller, comprise hex inverter chip and timer chip, after electric contact connects 5V power supply, timer chip control capacitance charging and discharging produce square wave repeatedly, this square wave exports to stepper motor driver control step machine operation through hex inverter chip.
7 pin cut-offs of described timer chip, capacitor charging, the charge circuit of electric capacity is that 5V power supply to the first resistance is to adjustable resistance to electric capacity to ground wire, 7 heel ground conductive of timer chip during low level, capacitor discharge, discharge loop is that 7 pin of electric capacity to adjustable resistance to timer chip are to ground wire.
Described hex inverter chip is the hex inverter chip of 74HCO4 model, and timer chip is the timer chip of 555 models.
The beneficial effects of the utility model are:
1, its circuit structure is simple, and production cost is low, easy to assembly, can be widely used in the continuous running such as track, streamline equipment and carry out Electric Machine Control.
2, it can reach by regulating the resistance of adjustable resistance the object regulating motor speed.
Accompanying drawing illustrates:
Fig. 1 is circuit diagram of the present utility model.
Embodiment:
Embodiment: as shown in Figure 1, simple motor controller, comprise hex inverter chip U1 and timer chip U2, after electric contact J1 connects 5V power supply VCC, timer chip U2 control capacitance C1 charging and discharging produce square wave repeatedly, this square wave exports to stepper motor driver control step machine operation through hex inverter chip U1.
The 7 pin cut-offs of described timer chip U2, electric capacity C1 charges, the charge circuit of electric capacity C1 is that 5V power supply VCC to the first resistance R1 to adjustable resistance R2 to electric capacity C1 is to ground wire GND, the 7 heel ground wire GND conductings of timer chip U2 during low level, electric capacity C1 discharges, and discharge loop is that 7 pin of electric capacity C1 to adjustable resistance R2 to timer chip U2 are to ground wire GND.
Described hex inverter chip U1 is the hex inverter chip of 74HCO4 model, and timer chip U2 is the timer chip of 555 models.
Operation principle: after electric contact J1 connects 5V power supply VCC, the then 7 pin cut-offs of timer chip U2, not with ground wire GND conducting, electric capacity C1 charges, charge circuit is that 5V power supply VCC to the first resistance R1 to adjustable resistance R2 to electric capacity C1 is to ground wire GND, capacity in electric capacity C1 exponentially rises, and when rising to TH value, output switching activity is low level.The 7 heel ground wire GND conductings of timer chip U2 during low level, electric capacity C1 discharges, discharge loop is that 7 pin of electric capacity C1 to adjustable resistance R2 to timer chip U2 are to ground wire GND, the capacity of electric capacity C1 exponentially declines, and when dropping to TL, output switching activity is high level, the 7 pin cut-offs of timer chip U2, electric capacity C1 charges again, so goes round and begins again, and produces and vibrates and form square wave.This square wave exports to stepper motor driver control step machine operation through hex inverter chip U1.
