Detailed description of the invention
A kind of linear-rotating motor, as shown in Fig. 1,2,3,4,5,6,7,8,9, including stator, mover 4, shell 1 and kinematic axis 5, described stator includes arc linear stator 2 and arc rotary stator 3, described arc linear stator fastens with arc rotary stator space, is placed in described shell, constitutes a cylinder type, share a mover, promote kinematic axis to do straight line, rotational or spiral motion.
Described arc linear stator is made up of arc linear stator unshakable in one's determination 6 and linear stator winding 7, arcuately. Described arc linear stator iron core is overrided to form vertically by the stalloy having teeth groove that shape is consistent, and its radian can adjust according to application scenario demand, it is shown that stator winding tamps in groove.After the logical three-phase alternating current of described arc linear stator, producing axial travelling-magnetic-field, by electromagnetic induction principle, produce faradic current in mover winding, actuation movement axle does rectilinear motion, constitutes linear motion unit.
Described arc rotary stator is made up of arc rotary stator core 8 and rotatable stator winding 9, curved, and its radian can adjust according to application scenario demand. Described arc rotary stator core is formed by silicon steel plate stacking, adopts salient-pole structure, and the rotatable stator tooth 15 of some salient poles is circumferentially uniformly distributed, and described rotatable stator winding is concentratred winding structure. After the energising of described arc rotary stator, according to " minimum reluctance " principle, namely magnetic flux always closes along the path of magnetic resistance minimum (magnetic conductance is maximum), and brought into motion axle rotates, and constitutes rotary motion unit.
As it is shown in figure 5, described mover 4 is made up of salient pole mover core 10 and mover winding 11. Fig. 6 show described salient pole mover core, silicon steel plate stacking form, and adopts salient-pole structure, and circumference is uniformly distributed some mover teeth 12. Described mover tooth circumferentially has circumferential slot 13, and axially equidistantly distributes along mover. Described mover winding tamps with mover circumferential slot, as it is shown in fig. 7, be the mover winding schematic diagram tamped, described mover winding 14 can be Wound-rotor type, it is also possible to conductor bar is made.
Described arc rotary stator constitutes rotary motion unit with salient pole mover core, and described rotary motion unit stator tooth and mover tooth elect three-phase 12/16 pole or 6/8 pole tooth fit structure as.
To the logical three-phase alternating current of arc linear stator, producing travelling-magnetic-field, according to electromagnetic induction principle, produce faradic current in mover winding, produce induced field in mover core, pushing motor does rectilinear motion. Rotating curved stator power supply mode is different from arc linear stator. As shown in Figure 8, for rotary motion unit schematic diagram, Fig. 9 is its B-B ' direction sectional view. This utility model is with three-phase 12/16 extremely example, because described arc rotary stator core is arc, its operation principle is consistent with traditional 6/4 pole switching reluctance motor. Be energized (i.e. A by stator A phase1、A2、A3、A4Winding energising on rotatable stator tooth), if now A1、A2、A3、A4Respectively just to M1Number, M3Number, M5Number, M7Number mover tooth, by A phase winding power-off, B phase winding is energized, then according to magnetic resistance minimum principle, salient pole mover is subject to clockwise torque, until rotatable stator tooth B1Just to M2Number mover tooth, B2、B3、B4The like. In like manner, by B phase winding power-off, C phase winding is energized, and salient pole mover continues to be subject to clockwise torque, until rotatable stator tooth C1Just to M3Number mover tooth, C2、C3、C4The like. If the relative position residing for fixed and moving son is as original position in Fig. 9, then giving A → B → C phase winding energising successively, salient pole mover rotates in a clockwise direction continuously; Otherwise, then motor can rotate in the counterclockwise direction. When arc linear stator and arc rotary stator are energized according to respective power supply mode simultaneously, motor can be spinned motion. This utility model adopts two set stator winding, by controlling the different "on" positions of stator winding, makes motor realize straight line, rotational or spiral motion.
This utility model adopts fluting salient pole Structure of mover, and when in Fig. 9, dotted portion is the energising of A phase rotatable stator winding, one is extremely descended magnetic circuit schematic diagram. When motion spinned by motor, although mover winding passes in and out the magnetic field that arc rotary stator produces axially movable, mover winding corresponding to arc rotary stator end position can produce faradic current, but may determine that according to the right-hand rule, the inductive current direction produced in the mover winding on two mover teeth corresponding under one pole magnetic circuit is contrary, cancelling out each other, when B phase is energized with C phase arcuate stator winding, situation is identical, and therefore rectilinear motion will not be produced impact by rotary motion unit.Owing to mover is salient pole toothing, the eddy current that arc linear stator produces on its surface is little, it is possible to ignore, it can thus be assumed that rotary motion is substantially free of impact by linear motion unit. Basic decoupling between two kinds of degree of freedom motions of a kind of linear-rotating motor that then this utility model is proposed, and there is compact conformation, being mechanically integrated height, the advantages such as starting current is little.
