Abstract
The invention discloses a frequency-conversion energy-saving stepping motor which comprises a system power supply, a control chip and a steeping motor body. The control chip is provided with a feedback circuit module, the control chip is connected with a frequency converter, and a frequency conversion drive is arranged between the frequency converter and the control chip and is connected with a power driving circuit of the stepping motor. Real-time monitoring of the stepping motor is achieved by the feedback circuit module and a rotating speed frequency monitor. The UDN2916LB chip is provided with overheat and intersection current protection functions and ensures safe running of a whole circuit device to some extent. The steeping motor is simple in structure, strong in controllability and good in low frequency running characteristic due to the fact that the frequency converter is used for conducting energy-saving modification on the stepping motor.
Description
Technical field
The present invention relates to a kind of controllable motor, especially a kind ofly can realize realizing according to actual needs that frequency conversion reaches the stepping motor of energy-conservation purpose.
Background technology
Stepping motor has obtained widely using in our life as the control motor, at engraving machine, and even the figure of stepping motor is arranged all on the receipt printing machine printer.Stepping motor is exactly electric impulse signal is changed into the open loop of angular displacement or displacement of the lines in brief and controls first stepping motor spare.Under the situation of non-overload, the frequency and the umber of pulse of pulse signal are only depended in rotating speed of motor, the position that stops, and do not receive the influence of load variations.According to this characteristic, we can control speed and the acceleration that motor rotates through the control impuls frequency, thereby reach the purpose of speed governing.
But the stepping motor that uses in the reality is because the restriction of condition can not utilize the adjusting of self to accomplish the task of speed governing on one's own initiative; Cause becoming common motor and carry out work, so just can not give play to the speed governing flexible characteristic of stepping motor fully at stepping motor many times.
The applicant through thinking and practice, realizes monitoring to actual demand through adding observation circuit and feedback circuit in this course, accomplishes the operating rate control to stepping motor through frequency converter, with the own characteristic of comprehensive performance stepping motor.
Summary of the invention
Goal of the invention: regulate inflexible present situation to prior art about step motor control, we grope through long-term practice aborning, have designed the energy-conservation stepping motor of a kind of variable ratio frequency changer.
Technical scheme: in order to realize the foregoing invention purpose; The technical scheme that the present invention adopted is: the energy-conservation stepping motor of a kind of variable ratio frequency changer; Comprise system power supply, control chip and stepping motor, said control chip is provided with a feedback circuit module, said control chip and a frequency converter; Be provided with a frequency conversion drive between said frequency converter and the control chip, this frequency conversion drive is connected with the power driving circuit of stepping motor.
Said feedback circuit module adopts current negative feedback circuit, and said feedback circuit links to each other with the speed-frequency monitor of stepping motor.
For the effect that realizes that stepping motor is energy-conservation; Second task just of the present invention; The control chip of applicant's design adopts the UDN2916LB chip; Operable here chip has a lot of selections, and the applicant selects to introduce particularly in the outstanding advantage beneficial effect below of UDN2916LB chip.
Beneficial effect: the present invention compared with prior art; Its beneficial effect is: 1, realize the real-time monitoring to stepping motor through feedback circuit module and a speed-frequency monitor, so just guaranteed when the perhaps present rotating speed of motor idle running requires above actual desired, can send signal to control chip in the very first time; 2, use the UDN2916LB chip as main control chip, this chip not only rich interface satisfies work requirements, and built-in overheated and crossover current defencive function, has protected the safe handling of entire circuit device to a certain extent; 3, adopt frequency converter that stepping motor is carried out reducing energy consumption, not only simple in structure, and also controllability is strong, and the low-frequency operation characteristic is good.
Description of drawings
Fig. 1 is the principle schematic of the energy-conservation stepping motor of a kind of variable ratio frequency changer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, technical scheme of the present invention is elaborated, but protection scope of the present invention is not limited to said embodiment.The present invention realizes the improvement on the flexible and controllable more at the utilization frequency converter to stepping motor; Single unit system should also comprise a stepping motor monitor speed module; But do not contact directly between this module and frequency converter and the feedback signal transmission, so do not do too much elaboration here.
As shown in Figure 1; The energy-conservation stepping motor of a kind of variable ratio frequency changer comprises system power supply, control chip and stepping motor, and the UDN2916LB chip is adopted in the control chip suggestion here; Said control chip is provided with a feedback circuit module; Said control chip and a frequency converter are provided with a frequency conversion drive between said frequency converter and the control chip, this frequency conversion drive is connected with the power driving circuit of stepping motor.
Said feedback circuit module adopts current negative feedback circuit, and said feedback circuit links to each other with the speed-frequency monitor of stepping motor.
In real work; When stepping motor monitor speed module is found that the rotating speed of present stepping motor is too fast or is not needed work or should realize displacement; Send signal to the power supply feedback circuit, through the turnover of power supply feedback circuit, control chip sends reduction of speed, stops the perhaps instruction of displacement to frequency converter; The state that changes power driving circuit is realized Stepping Motor Control, realizes the stepping motor reduction of speed, stops the perhaps final purpose of displacement.
