Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
As Fig. 1, Fig. 2, the stepping motor of the acceleration and deceleration of a kind of S type curve controlled shown in Fig. 3, is characterized in that: by cap 1, motor body 2, rotating shaft 11 and connect plug 12 and form, described motor body 2 is positioned at the side of cap 1, described motor body 2 and cap 1 are for being fixedly connected with, described cap 1 is also provided with bearing 3, described bearing 3 is positioned at the middle part of cap 1, described bearing 3 and rotating shaft 11, for being fixedly connected with, described motor body 2 are also provided with front rotor 4, front speed control rotating shaft 5, permanent-magnet steel 6, rear speed control rotating shaft 7, rear rotor 8, coil 9 and stator 10, described front rotor 4 is positioned at the inside of motor body 2, described front rotor 4 and rotating shaft 11 are for being fixedly connected with, described front speed control rotating shaft 5 is positioned at the side of front rotor 4, described front speed control rotating shaft 5 with rotating shaft 11 for being fixedly connected with, described permanent-magnet steel 6 is positioned at the side of front speed control rotating shaft 5, described permanent-magnet steel 6 and rotating shaft 11 are for being fixedly connected with, described rear speed control rotating shaft 7 is positioned at the side of permanent-magnet steel 6, described rear speed control rotating shaft 7 with rotating shaft 11 for being fixedly connected with, described rear rotor 8 is positioned at the side of rear speed control rotating shaft 7, and described rear rotor 8 is with rotating shaft 11 for being fixedly connected with, and described coil 9 is positioned at front speed control rotating shaft 5, the outside of permanent-magnet steel 6 and rear speed control rotating shaft 7, described coil 9 and stator 10 are for being fixedly connected with, and described stator 10 is positioned at the outside of coil 9, and described stator 10 and motor body 2 are for being fixedly connected with, described rotating shaft 11 is positioned at the inner side of cap 1 and motor body 2, and described rotating shaft 11 runs through bearing 3, front rotor 4, front speed control rotating shaft 5, permanent-magnet steel 6, rear speed control rotating shaft 7, rear rotor 8, coil 9 and stator 10 are for being fixedly connected with.This stepping motor described is opened loop control element, and the signal sent is pulse control signal.Described bearing 3 is ball bearing.Described front speed control rotating shaft 5 is the ball bearing of these auxiliary acceleration and deceleration in stepping motor inside.Described rear speed control rotating shaft 7 is the ball bearing of these auxiliary acceleration and deceleration in stepping motor inside.The described stitch connecing plug 12 is conducting metal material.
Working method: this stepping motor speed control rotating shaft 7 after the permanent-magnet steel both sides of motor body 2 inside are equipped with a front speed control rotating shaft 5 and respectively, these two speed control rotating shafts are all the feed speed control adopting the ball bearing of acceleration and deceleration to carry out auxiliary adjustment stepping motor, and coordinate control system.This step motor control system singlechip chip and integrated interface is utilized cap 1 that assembly bearing 3, front rotor 4, front speed control rotating shaft 5, permanent-magnet steel 6, rear speed control rotating shaft 7, rear rotor 8, coil 9 and stator 10 are all encapsulated in control system inside, can reduce the volume of system like this; And the assembling simplifying system forms step.Send pulse signal by the singlechip chip of single-chip computer control system inside and be delivered in control system by integrated interface, then being integrated by control system and analyzed, instruction is passed to stepping motor by power control line, having carried out the control to load.This system adopts S type curve feed speed control to the control of stepping motor.Mainly solve S curve in motion control to be difficult to determine, to be difficult to the problem that regulates at any time, find out one and perfect can agree with function that arbitrary motion controls to determine S rate curve, and it is discrete, obtain complete speed simulation form.
The tangent mode of identical, that opening direction the is contrary parabola of two strips is used to construct a S curve in the middle of this system.Wherein, the parabolical symmetry axis of opening upwards is y-axis, as shown in Figure 3.Parabola y1 is identical with y2 parabolic shape.Therefore the openings of sizes of y1 with y2 is identical, therefore the value of a is equal.
As shown in Figure 3, make parabola y1 and y2 symmetrical about point of contact.The symmetry axis of parabola y2 is x=-b, then the abscissa at point of contact is
Again point of contact coordinate is substituted into two parabolical formula: y1=ax respectively 2+ c1 and y2=-a (x+b) 2+ c2, simultaneous equations can obtain: summit formula from parabola y2: c2 is the maximum speed in rate curve.C 1 is the toggle speed of motor.
By arranging toggle speed and maximum speed and parabolical openings of sizes a, we can construct a complete S curve completely.And the absolute value of a determines parabolical openings of sizes, a is larger, and opening is larger, and curve is more slow, otherwise curve is steeper.
When t value is less than the abscissa at point of contact, we use the formula of parabola y1 to calculate present speed; When t value is more than or equal to point of contact abscissa, we use the formula of parabola y2 to calculate present speed.So just, the discrete point of rate curve can be obtained.By speed data stored in array, when motor accelerates, read forward fetches data; The reverse read data when decelerating through motor.If heavier loads, can coordinate motor segment realize smoothness run, ensure that motor without lose step and without overshoot.On this basis, we can by accurately controlling the run location of motor to the control of number of motor steps.
In sum, this step motor control system only needs minimum operation speed c1, the highest running speed c2 and parameter a of given motor, can determining a complete S curve, by adjusting this 3 parameters, can regulate the smoothness of S curve.Therefore, from theory, this control mode is applicable to any one step motor control system.According to used hardware and mechanical facility, coordinating segmentation, by adjusting above 3 parameters, always can find optimized parameter; And this system institute operation parameter is less, and the no-load speed of minimum operation speed and motor, namely highest running speed expects the maximum speed reached.Therefore enormously simplify calculating process, reduce operand; Its computing formula used only has two, makes people very clear, is convenient to designer's programming and safeguards.And this S curve control mode can be transplanted to the application platform of arbitrary stepping motor, and motor operates steadily, and noise is minimum, meets system requirements completely; There is very high practical value.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
