Abstract
The invention relates to a control driving module of a double AC motor, and belongs to the technical field of electronic control and drive of DC motors. The control driving module of the double AC motor comprises a 5V voltage stabilizing circuit, an encoding circuit with one signal input and two-way output, and an L298N driving circuit; the output end of the driving circuit is connected with the DC motor. According to the control driving module of the double AC motor, the signal of the input end of the L298N driving circuit can be distributed through a diode according to the one-way conductivity of the diode, and therefore, the rotating directions of the two DC motors can be synchronously controlled by inputting simple signal; the control driving module of the double AC motor has the outstanding advantage that different single signal sources directly synchronously control the rotating directions of the two motors without program control; the control driving module further has the characteristics of being low in power consumption, fast to dynamically respond, stable in performance, safe and reliable, and particularly suitable for primary and secondary school students designing a remote toy car by self without knowledge on programming.

Technical field
The present invention relates to two direct current motor control drive module, belong to the electronic technology field that DC MOTOR CONTROL drives, achieve the input of different single signal and can control the function that two direct current machines turn to simultaneously; Be particularly suitable for the students in middle and primary schools DIY remote-controlled toy vehicle being ignorant of programming.
Background technology
At present, on market, direct current motor control drive module is by mcu programming control mode mostly, and this patten's design is complicated, and cost is higher, and the personage being not suitable for being ignorant of programming makes telecar; And although the driver module cost merely using mould power technology to design is lower, needs a large amount of welding, concerning non-technical personnel, have certain danger, can not necessary requirement be reached.
Summary of the invention
The object of the invention is to, overcome the technical disadvantages of existing L298N chip, a kind of two direct current motor control drive modules be simple and easy to are provided, realize different single signal and can control the function that two direct current machines turn to simultaneously, reach and input separately that four signals just can make toy car realize advancing, turn left, turn right, the object of fallback function successively.
Technical scheme of the present invention is: a kind of two direct current motor control drive module, comprises: a coding circuit utilizing the one-way conduction characteristic of diode to realize a signal input two-way output; A 5V voltage stabilizing circuit utilizing 7805 voltage stabilizing chips and electric capacity to form; The two direct current motor drive circuits utilizing L298N driving chip to set up.
The output of described drive circuit directly connects with direct current machine.
In described drive circuit, the effect of diode provides freewheeling path to motor coil, burns out chip when preventing motor from stopping suddenly.
Described coding circuit compound mode can realize the function that single signal inputs two signals outputs, avoids the signal cross interference problem of control two motors.
Obvious technical effects of the present invention: the coding circuit become by diode combinations controls the input of drive circuit, different single signal can be realized and can control the function that two direct current machines turn to simultaneously, save the programming of control section, facilitate the making of non-electronic design specialist personage.
