Description
Technical Field
The utility model relates to an improved intelligent household motor, in particular to an improved DC brushless motor for intelligently driving a curtain to open and close.
Background
At present the intelligent (window) curtain motor of generally used mostly has the brush motor, and the conventionality has the brush motor to be a rotor, and fore-and-aft output shaft direction of operation is the same, and it is more complicated to open and shut the drive structure in addition, and the cost is very high, appears the (window) curtain position unstability that opens and shuts easily in the in-service use, influences user's use and experiences the effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a DC brushless motor of rational in infrastructure, both ends positive reverse output.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: the direct-current brushless motor comprises a stator, a rotor, a power line and a drive plate, wherein the power line is connected with the drive plate, and the direct-current brushless motor is characterized in that: the rotor comprises a first output shaft and a second output shaft which are rotatably arranged, shaft sleeves are respectively arranged on the first output shaft and the second output shaft, magnetic shoes are arranged outside the shaft sleeves, and a partition plate is arranged between the first output shaft and the second output shaft; the stator comprises a first coil assembly and a second coil assembly, the first coil assembly corresponds to a magnetic shoe of a first output shaft, the second coil assembly corresponds to a magnetic shoe of a second output shaft, phase lines of the first coil assembly and the second coil assembly are connected in parallel to a drive plate, and the first coil assembly and the second coil assembly are provided with a phase line arrangement sequence for driving the first output shaft and the second output shaft to rotate in opposite directions.
And rolling bearings for supporting two ends of the first output shaft are respectively arranged on the rear end cover of the motor and the partition plate, and rolling bearings for supporting two ends of the second output shaft are respectively arranged on the front end cover of the motor and the partition plate.
And an elastic washer is arranged between the shaft sleeve and the rolling bearing.
The magnetic shoe is made of rare earth aluminum iron boron.
The first output shaft and the second output shaft are arranged coaxially
The beneficial effects of the utility model are that the brushless DC motor after the improvement, the direction of rotation of first output shaft and second output shaft is opposite, uses just very conveniently on the (window) curtain that opens and shuts, because the (window) curtain that opens and shuts whether open or fold the direction of seeing both sides from the centre is opposite, with this kind of motor structure that opens and shuts will be simple relatively and low price, but the effect is better.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. The direct current brushless motor comprises a stator, a rotor, a power line 1 and a drive plate 2, wherein the power line 1 is connected with the drive plate 2, the rotor comprises a first output shaft 3 and a second output shaft 4 which are rotatably arranged, the first output shaft 3 and the second output shaft 4 are coaxially arranged, shaft sleeves 5 are respectively arranged on the first output shaft 3 and the second output shaft 4, magnetic shoes 6 are arranged outside the shaft sleeves 5, and a partition plate 7 is arranged between the first output shaft 3 and the second output shaft 4; the stator comprises a first coil component 8 and a second coil component 9, the first coil component 8 and the second coil component 9 both comprise a stator piece and a coil wound on the stator piece, the first coil component 8 is corresponding to the magnetic shoe 6 of the first output shaft 3 to drive the first coil component, the second coil component 9 is corresponding to the magnetic shoe 6 of the second output shaft 4 to drive the second coil component, phase lines of the first coil component 8 and the second coil component 9 are connected in parallel to the driving plate 2, and the first coil assembly 8 and the second coil assembly 9 have a phase line arrangement order for driving the first output shaft 3 and the second output shaft 4 to rotate in opposite directions, the arrangement order of the phase lines of the first coil assembly 8 and the second coil assembly 9 can be adjusted (the rotation direction of the first output shaft 3 and the second output shaft 4 of the motor can be determined by the arrangement order of the phase lines).
The rear end cover 10 and the partition plate 7 of the motor are respectively provided with rolling bearings 11 for supporting two ends of the first output shaft 3, and the front end cover 12 and the partition plate 7 of the motor are respectively provided with rolling bearings 11 for supporting two ends of the second output shaft 4.
An elastic washer 13 is arranged between the shaft sleeve 5 and the rolling bearing 11.
The magnetic shoe 6 is made of rare earth aluminum iron boron, so that the output torque is much larger than that of the conventional motor, and the practicability of the motor is greatly improved.
The utility model discloses an operating principle, when power cord 1 switch on, drive plate 2 begins work, thereby the coil can produce a rotating magnetic field drive rotor continuous operation, because the phase line of first coil pack 8 and second coil pack 9 adopts and connects into drive plate 2 mode in parallel, and first output shaft 3 and second output shaft 4 adopt independent mode separately by middle division board 7, so first output shaft 3 and second output shaft 4 all can rotate according to the direction of rotation of oneself in succession simultaneously, for obtaining different direction of rotation, the order of arranging of phase line of adjustable first coil pack 8 and second coil pack 9.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
