Abstract
The utility model relates to a motor driving device, which comprises a motor, a shaft and a driving device, wherein the driving device is composed of a magnetic steel and a magnetic ring, the magnetic steel is sheathed on a magnetic steel fixing seat connected with a motor shaft and is arranged in an inner sleeve provided with the magnetic ring, an outer sleeve is arranged outside the inner sleeve which is freely rotated in the outer sleeve, one end of the shaft sheathed with teeth passes through the outer sleeve to be connected with the center of the inner sleeve and both ends of the outer sleeve are fixed on an iron plate. After the utility model adopts the structure, when the motor driving device is energized, the motor is rotated, and the magnetic steel is driven to rotate; on one hand, because the magnetic steel and the magnetic ring generate magnetic force attracted with each other, the rotating moment of the motor is increased, and on the other hand, the motor drives the magnetic steel to rotate, the magnetic steel drives the inner sleeve attracted by the magnetic force and provided with the magnetic ring to freely rotate in the outer sleeve so that the utility model effectively prevents the problem that the motor also works to be burnt out when a valve is opened and closed to an upper and a lower dead points.
Description
Technical field
The utility model belongs to a kind of motor drive unit, the drive unit that particularly a kind of control valve opens and closes.
Background technique
In the prior art, be widely used in industrial motor drive unit, all have the driven by motor valve, valve opening and closing is during to upper and lower stop, and motor also in work, burns out the problem of motor, and wastes energy, and cost is improved.
Summary of the invention
In order to overcome shortcoming of the prior art, technical problem to be solved in the utility model provides and a kind ofly makes motor idle running and do not burn out motor, and labour-saving motor drive unit more.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: motor drive unit, comprise motor, axle and drive unit, described drive unit is made up of magnet steel and magnet ring, and magnetic steel sleeve and is packed into and is provided with in the interior cover of magnet ring on the magnet steel fixed base that is connected with motor shaft, the outer overcoat that is provided with of interior cover, in be enclosed within and freely rotate in the overcoat, be with tooth spool an end pass overcoat and link to each other with interior cover center, the two ends of overcoat are fixed on the iron plate.After adopting this spline structure, as energising, motor rotates, and drives the magnet steel rotation, on the one hand, because magnet steel produces the magnetic force of inhaling mutually with magnet ring, increased the moment that motor rotates greatly, on the other hand, the driven by motor magnet steel rotates, magnet steel drive by magnetic force inhale mutually and be equipped with magnet ring in be enclosed within the overcoat and freely rotate, when having prevented that effectively valve opening and closing from arriving upper and lower stop, motor also burns out the generation of motor problem in work.
In order to solve the problems of the technologies described above, the utility model adopts following further technological scheme: magnet steel and magnet ring be annular, adopt this shape after, magnetic force distribution uniform on the one hand also cooperates the needs of motor rotation on the other hand.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Describe in detail below in conjunction with accompanying drawing.
As can be seen from the figure, the utility model comprises motor 1, axle 2 and drive unit 3, drive unit 3 is made up of magnet steel 4 and magnet ring 5, magnet steel 4 is enclosed within on the magnet steel fixed base 6 that is connected with motor shaft, and 7 li in the interior cover of packing into and being provided with magnet ring 5, interior cover 7 is outer to be provided with overcoat 8, be provided with between interior cover 7 and the overcoat 8 overlap in keeping 7 in overcoat 8 free rotating space 11, an end that is with the axle 2 of tooth 9 passes overcoat 8 and links to each other with interior cover 7 centers, and the two ends of overcoat 8 are fixed on the iron plate 10.In this example, magnet steel 4, magnet ring 5, magnet steel fixed base 6, interior cover 7, overcoat 8 all are made as ring.
During use, logical powering on, motor rotates, and the magnet steel 4 that drives on the magnet steel fixed base 6 rotates, magnet steel 4 drives by magnetic force to be inhaled and interior cover 7 that magnet ring 5 is housed rotates in overcoat 8 mutually, interior cover 7 also drives axle 2 when rotating and rotates, thereby drive tooth 9 reaches the purpose of accessories such as opening/shutting valve to outside conveying capacity distance.
The utility model is simple in structure, and price is low, is a kind of drive unit that drives various valves that is applicable to.
