Abstract
An intelligent AC three-phase motor stepless speed regulation module which decides to control the rotation speed of a three-phase AC motor according to changes of outer temperature carries out DC conversion on inputted three-phase AC into DC, the magnitude of output voltage is controlled or regulated on a DC part, DC voltage after change is simulated into sine waves to be outputted to the three-phase AC motor, and thus the purpose of changing the rotation speed of the motor is realized. The module is cooled on a fan, and thus an intelligent stepless speed regulation fan is formed.
Description
Art
The present invention relates to and a kind ofly can be decided to control three phase alternating current motor rotating speed intelligent AC three phase electric machine stepless time adjustment module by the change of ambient temperature, by this module for cooling fan, namely define Intelligent electrodeless speed-regulating fan.
Background technology
At present, the method for mode of speed regulation many employings frequency conversion of known three phase alternating current motor changes motor speed.This form can change the rotating speed problem of alternating current machine really.But device used is more when changing frequency, complex manufacturing and cost intensive.
In order to solve the complex process relying on frequency modulation to come in speed governing, high cost problem, we devise intelligent three-phase stepless time adjustment module.
Summary of the invention
First we carry out DC converting to the three-phase alternating current that input comes, after being transformed into direct current, direct current component controls the size of output voltage or regulates, then the direct voltage after change is modeled to sinewave output to three phase alternating current motor, so just reaches the object changing motor speed.
The technical solution adopted for the present invention to solve the technical problems is: the three-phase alternating current that input comes is done DC converting, direct voltage after conversion is input to ARM controller, because technique is the temperature regulate speed for fan by we, so we are provided with temp probe DS18B20 interface on ABM controller, RS485 computer interface.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is Intelligent electrodeless speed-regulating fan inside modules structure of the present invention.
Embodiment
During use, give first by several temperature nodes of computer settings, then each node is set a motor speed, when temp probe passes temperature signal back, ARM controller can reconcile output voltage according to the program of setting in advance, output voltage after conciliation is adjusted to sine voltage through simulator, is supplied to motor, motor is arranged according to the rotating speed of the temperature nodes of setting and rotates, thus reach the object of speed governing.
Start under big current to not make motor, by program setting, in certain low-temperature values, on the temperature value of setting, motor just starts to start for we, when temperature progressively raises, ARM controller can arrange raising output voltage according to the program arranged progressively according to temperature nodes, reaches the object progressively improving motor speed.
Because motor is in low-voltage, start under low current, low speed state, therefore without the need to large operating current, when temp probe passes the temperature of the highest setting back, this motor just can reach rated speed, the namely maximum (operating current) of electric current needed for motor, and this motor operationally, normally between the slow-speed of revolution and high rotating speed, seldom reach motor to operate at full capacity state, namely seldom reach rated voltage, rated current state, noiselessness during work, pollution-free, therefore, it has the features such as energy-saving and environmental protection, cost are low, easy adjustment.
