The accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the fan circuit that provides of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
The utility model embodiment provides a kind of fan circuit, and referring to Fig. 1, described fan circuit is comprised of the drive controller 1, speed setting module 2, motor drive module 3, motor 4, the current sampling module 5 that are electrically connected to.
Particularly, the output terminal of drive controller 1 is connected with the input end of motor drive module 3, and three phase lines by motor 4 make drive controller 1 be connected with motor drive module 3, motor 4 successively, does not need the position signal feedback, and antijamming capability is strong.Motor 4 is drawn three phase lines, and similar AC three-phase motor is simple in structure, the convenient manufacture, and good reliability, with low cost.
Particularly, speed setting module 2 is connected with the input end of drive controller 1, and the rotary speed instruction of setting is sent to drive controller 1.Speed setting module 2 has potentiometer 21; Preferably, potentiometer 21 has one, only with a potentiometer 21, realizes the rotating speed stageless setting, fully represents the characteristics of DC frequency-changing fan wide speed range, and circuit is simple and reliable, and cost is low.
Particularly, the output terminal of motor drive module 3 is connected with the winding of motor 4, and motor drive module 3 becomes one with power supply 6, and separates setting with motor 4, and simple in structure, manufacturing efficiency is high, facilitates after-sales service.
Particularly, current sampling module 5 is connected in drive controller 1 by feedback signal one end, and the other end is connected in motor drive module 3.Current sampling module 5 can be by the currrent feedback in motor drive module 3 to drive controller 1, more further regulates motor speed.
The input end of drive controller 1 connects speed setting module 2, the output terminal of drive controller 1 connects the input end of motor drive module 3, the output terminal of motor drive module 3 is connected with the winding of motor 4, current sampling module 5 is connected in drive controller 1 by feedback signal one end, and the other end is connected in motor drive module 3.
After drive controller 1 receives the rotary speed instruction of speed setting module 2 settings, rotary speed instruction is assigned to coupled motor drive module 3, motor drive module 3 makes motor 4 rotate again, simultaneously, current sampling module 5 again by the currrent feedback in motor drive module 3 to drive controller 1, more further regulate motor speed.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is: this fan circuit is simple in structure, good stability, reliability are high, with low cost.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
