Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
To shown in Figure 6, the asymmetric two-sided linear switched reluctance motor of present embodiment comprises base 1, mover 2, three stator pack 3 and is located at stator coil A, A ', B, B ', C, C ' on each stator as Fig. 1.Base 1 is fixing, and it is as the support of this switched reluctance machines.Mover 2 moves with base 1 straight line and cooperates, and this mover 2 can be moved at the directions X straight line relative to this base 1.Mover 2 has left side and the right side of extending at directions X, and the mover tooth 21 that this left side and right side all have outside protrusion and be arranged in a row at directions X form teeth groove 22 between two adjacent mover teeth 21, and the mover tooth on the mover tooth in left side and right side is asymmetric.Each stator pack 3 includes two stators, and these two stators are all fixing with base 1, and these two stators lay respectively at left side and the right side of mover, and these two stators are asymmetric about this mover.All there are three stators the both sides of mover 2, a stator right opposite of each stator and other stator pack.Each stator all has the stator tooth 31 that protrudes to mover tooth 21.The stator tooth 31 of each stator 3A, 3A ', 3B, 3B ', 3C, 3C ' has a plurality of, and a plurality of stator tooths of each stator 31 are arranged in a row at directions X.Has air gap 4 between stator tooth 31 and the mover tooth 21.
Three stator pack can be defined as A phase, B phase and C respectively mutually.As the stator tooth 31 of a certain phase stator during with 21 alignment of mover tooth (as B stator 3B, 3B ' mutually), the stator tooth of two-phase stator does not line up (as A stator 3A, 3A ' and C stator 3C, 3C ' mutually mutually) with the mover tooth in addition.Detect the relative position of stator tooth and mover tooth by transducer, give an energising mutually wherein, as shown in Figure 6, as switching on for A mutually, then this moment, stator coil A and stator coil A ' all produced magnetic flux, and magnetic flux is by behind stator tooth 31, air gap 4 and the mover tooth 21, return stator tooth 31 and form the loop, and magnetic flux has the character of passing through along the path of magnetic resistance minimum, and produce electromagnet pull this moment, forces A phase stator tooth 31 and 21 alignment of mover tooth.Because stator fixes, electromagnet pull drags mover 2 and moves forward at directions X; After moving into place, 21 alignment of A phase stator tooth 31 and mover tooth, stator tooth 31 and mover tooth 21 all do not line up mutually and C is mutually with A.As switching on for C mutually, the electromagnet pull of generation can force C phase stator tooth and the alignment of mover tooth again, and A stator tooth and the mover tooth of stator do not line up mutually with B mutually.That is, for the threephase switch reluctance motor, general, in the time of a certain aligning, two-phase does not line up in addition, and as shown in Figure 6, B aligns this moment, and A does not line up mutually with C mutually, if switch on for C mutually, mover 2 will be moved to the left this moment, switches on mutually as giving A, then mover 2 will move right, thereby can guarantee that motor moves towards both direction.
In the present embodiment, the B phase stator 3B ' in left side and the A phase stator 3A on right side face mutually, and the C phase stator 3C ' in left side and the B phase stator 3B on right side face mutually, and the A phase stator 3A ' in left side and the C phase stator 3C on right side face mutually.Certainly, also can be the left side B, C, A phase stator face mutually with C, A, the B phase stator on right side respectively; Or the B in left side, C, A phase stator are faced mutually with A, B, the C phase stator on right side respectively.That is, the asymmetric both sides that are located at mover 2 of two stators of each stator pack 3, namely two of this group stators are faced mutually with the stator of other group.
For asymmetric two-sided linear switched reluctance motor, mover tooth 31 can be strip shape body, as the strip shape body that extends in the Z direction; Corresponding, stator tooth also can be strip shape body.
For asymmetric two-sided linear switched reluctance motor, the mover tooth 21 of the left and right side of mover all can wait tooth pitch evenly to distribute.The asymmetric distribution of mover tooth of the left and right sides, but the left side is when being mover tooth 21, the right side is teeth groove 22; When the right side was the mover tooth, the left side was teeth groove 22.The stator tooth 31 of each stator also can be to wait tooth pitch evenly to distribute.The tooth pitch of mover tooth and the tooth pitch of stator tooth can equate.The facewidth of mover tooth and the facewidth of stator tooth also can equate.Mover tooth 21 also can equate with air gap 4 between the stator tooth 31.Tooth pitch be on directions X, the spacing of adjacent two stator tooths or mover tooth.The facewidth be on directions X, the width of stator tooth or mover tooth.Air gap be on Y-direction, the spacing of stator tooth and mover tooth.Certainly, the relativeness of the tooth pitch of mover tooth, stator tooth, the facewidth and air gap can design as requested.
