Description
Technical field
The present invention is the stator structure about a kind of motor, particularly a kind of stator structure that has motor activation off normal function and do not reduce a kind of motor of motor rotation efficiency.
Background technology
Motor is because can convert electric energy to rotational kinetic energy easily, so in general mechanical structure, usually can see the application of motor.
The motor of prior art system usually is made of a stator and a rotor, be equipped with stator component around the stator, the preferably can be formed by silicon steel sheet, and on stator component, twine at least one coil, and the inboard of rotor is provided with magnet with respect to the position of the stator component of stator, when having electric current to flow through in the above-mentioned coil, can make stator component excite magnetic force, the effect of the position of the magnet of cooperation rotor inboard, can make rotor see through a rotating shaft and rotate, reach the function of motor running with respect to stator.
A kind of prior art is applied to stator structure 1 in the motor and please refer to shown in Figure 1ly, and stator structure 1 includes a stator component 10, one auxilliary pole piece 12 and at least one coil 14; Wherein, stator component 10 is to be formed by stacking by the identical sheet metal 100 of a plurality of shapes, please refer to Fig. 2, it shown in the figure outward appearance schematic top plan view of sheet metal 100, sheet metal 100 is made up of a fixed part 1000 and a plurality of magnetic pole piece 1001, wherein, comprises a fixing hole 1003 in the fixed part 1000, be with fixing whole stator structure 1, and magnetic pole piece 1001 is to stretch out from fixed part 1000 so that an axle center (not shown) wears; Auxilliary 12 tops that are fixedly arranged on stator component 10 of pole piece wherein include a plurality of auxilliary pole-faces 120, lay respectively in the space between per two magnetic pole pieces 1001.
The motor of prior art is in order to possess the off normal of activation function, in the stator component 10 in the above-mentioned stator structure 1, the outer shroud periphery 1002 of its magnetic pole piece 1001 design usually is made up of the circular arc periphery of a plurality of different radiis, please refer to shown in Figure 2, the outer shroud periphery 1002 of magnetic pole piece 1001 for example is made up of two outer shroud peripheries of radius R 1 and radius R 2, and wherein radius R 1 is not equal to radius R 2; Or, please refer to shown in Figure 3ly, the another kind of outer shroud periphery 1004 of magnetic pole piece 1001 can also be made up of two outer shroud peripheries of radius R 3 and radius R 4, and has one section difference between the outer shroud periphery of two different radiis; So, when the coil 14 that is wound in this stator component 10 has electric current to flow through, having the magnetic direction that the circular arc periphery of different radii produced can be different, and the difference of this magnetic direction can produce the magnetic force component of a tangent line direction when motor activates, make motor can be smoothly by static and activate; But, also be because so, the magnetic force that coil excited fully is not applied to make the motor rotation, so its motor rotation efficiency is lower.
In addition, referring again to Fig. 1, the rotor (not shown) of the motor of prior art is when rotation, if the space between per two magnetic pole pieces 1001 in its stator structure 1 is too big, with the magnet that makes rotor during with respect to those spaces, because the dispersion of the magnetic line of force is discontinuous, magnet moment of rotor can't induced magnetism, and produces the phenomenon that the rotor rotation pauses; For head it off, still include an auxilliary pole piece 12 in the stator structure 1 of prior art, be fixedly arranged on the top of stator component 10, the a plurality of auxilliary pole-face 120 of auxilliary pole piece 12 lays respectively in the space between per two magnetic pole pieces 1001, stator component 10 is subjected to exciting when producing the magnetic line of force through these spaces, can make the unlikely dispersion of the magnetic line of force by auxilliary pole-face 120, and can continue to provide rotor magnetic, make to reduce to produce the phenomenon that the rotor rotation pauses; In addition, the another kind of mode that solves of prior art is that stator structure 2 provides the stator component 11 that itself has auxilliary utmost point portion 112, please refer to shown in Figure 5, stator component 11 is that sheet metal 110 identical by a plurality of shapes and that have an auxilliary pole piece 1104 is formed by stacking, auxilliary pole piece 1104 is to be extended out by fixed part 1000, wherein, the fixing hole 1003 same systems of fixed part 1000 are with fix whole stator structure 2 so that an axle center (not shown) wears, after a plurality of sheet metal 110 is superimposed, auxilliary pole piece 1104 just is overlapped into auxilliary utmost point portion 112, has equally to reduce the effect that produces rotor rotation break; But, such structure, auxilliary utmost point portion 112 but has and stops that easily coil is wound in the shortcoming of stator component 11, that is to say, on the stator component of same dimensions, above-mentioned structure can can't be twined more coil owing to assist the existence of utmost point portion, and making does not have elasticity on the motors designs.
