In order to overcome the problems such as current stepping motor generates heat, volume is large, energy utilization rate is low, the utility model provides a kind of stator Follow-up type stepping motor device, this device adopts stator and the stepping of rotor step type to promote principle, by stator drive rotor, stepped further, then stator follows rotor rotation direction closely again with further, circulation constantly, realizes rotor stepping rotation successively.
The utility model mainly by housing, stator, rotor, place restrictions on tooth, unidirectional top, single direction turning mechanism, stator lock and form.Stator lock is located on housing, the stator of the state of quitting work is locked, or also can not set sub-lock on housing.Stator connects with housing by one-way movement stride device or stator connects with housing by single direction turning mechanism.One-way movement stride device is by placing restrictions on tooth and unidirectional top forms.Place restrictions on tooth and connect with housing, unidirectional top connects with stator or unidirectional top connects with housing, places restrictions on tooth and connects with stator.Opening and closing movement can be made in unidirectional top on stator or housing, controls stator and only does one-way movement.Unidirectional top magnitude setting is not limit, and along can equidistantly arranging in week or equidistantly not arranging, unidirectional top can all enter or enter in order and place restrictions in tooth tooth in batches.Placing restrictions on the geometry of tooth profile of tooth does not limit.Stator is limited by one-way movement stride device or single direction turning mechanism, can only one-directional rotation, can not rotate backward.The rotation of one-way movement stride device and single direction turning mechanism is towards changing.Rotor connects with stator or rotor connects with housing by single direction turning mechanism, and rotor is subject to single direction turning mechanism restriction only to make one-directional rotation.Stator rotation direction is identical with rotor rotation direction.Rotor magnetic pole is between stator two magnetic poles.Rotor magnetic pole and magnetic pole of the stator can adopt interlock combining structure, in rotor magnetic pole enters between adjacent two magnetic poles of stator, or rotor magnetic pole and magnetic pole of the stator also can adopt inside and outside combining structure, rotor magnetic pole is arranged in magnetic pole of the stator internal diameter, or rotor magnetic pole and magnetic pole of the stator also can adopt half bag combining structure, rotor magnetic pole have two or three or magnetic pole of the stator corresponding with magnetic pole of the stator have two or three corresponding with rotor magnetic pole, or rotor and stator also can adopt face face combining structure, rotor is arranged on the left side, stator is arranged on the right or rotor is arranged on the right, stator is arranged on the left side.Rotor magnetic pole polarity is constant, and magnetic pole of the stator alternating polarity changes or rotor magnetic pole alternating polarity changes, and magnetic pole of the stator polarity is constant.
Adopt rotor magnetic pole polarity constant, magnetic pole of the stator alternating polarity changes design, when starting working, stator lock is first to stator quick release, stator enters operating state, now, when magnetic pole of the stator polarity is identical with adjacent rotor pole polarity, magnetic repulsive force will act on stator and rotor simultaneously.Because stator turns to, limited by one-way movement stride device or single direction turning mechanism, can only enter and can not move back, therefore magnetic repulsive force can only act on rotor, drive rotor stops while moving to the position of magnetic pole of the next opposed polarity of stator.So far, rotor has rotated a step.Subsequently, magnetic pole of the stator reversing, stator and rotor are subject to the effect of contrary magnetive attraction simultaneously, and because rotor is subject to motional inertia and load-carrying restriction, slow or limited by single direction turning mechanism to the reaction of contrary moment, rotor can not counter motion.And there are not these restraining factors of rotor in stator, fast to moment reaction speed, can towards rotor rotation direction, follow further rapidly, make stator get back to again the original position corresponding with rotor.Meanwhile, stator also drives unidirectional top or places restrictions on tooth and placing restrictions on distance mobile certain on tooth or unidirectional top.Unidirectional top and place restrictions on tooth and not only can limit stator and only enter the effect that can not move back, can also make adjustments automatically to the each motion step pitch error of stator.Iterative cycles like this, rotor just, under magnetive attraction promotes, travels forward step by step, stator follow-up forward step by step under magnetive attraction promotes equally.When quitting work, stator lock can, fast by stator locking, be prevented the inertia motion of stator.Rotor and stator be outputting power externally.The motion step number of rotor and stator is relevant to magnetic pole of the stator alternating polarity change frequency.If adopt rotor magnetic pole alternating polarity to change, the constant design of magnetic pole of the stator polarity, its operation principle is same as described above.
The beneficial effects of the utility model are, adopt the motor of stator Follow-up type drive rotor stepping, because the magnetic action power between rotor transforms in work done substantially, so not only energy utilization rate is high, starting power is apart from large, heating is few and can manufacture high-power stepper motor, and motor consumptive material is few, volume is little, lightweight and can do slowspeed machine use etc.
