Abstract
The utility model relates to a stepping motor structure, which comprises a stator, a rotor, a shaft, a left end cover, a right end cover, a left bearing and a right bearing. The stator and the rotor are concentric and have a gap. The stator is provided with a plurality of magnetic poles. Each magnetic pole is provided with a plurality of stator teeth. A stator tooth groove is arranged between each two stator teeth. A monopole tooth rack is embedded in each stator tooth groove. The magnetic pole direction of the monopole tooth rack is opposite to the magnetism of a rotor iron core which is dead against with the monopole tooth rack. Compared with the prior art, the utility model has the same thickness, improves the output torque and efficiency of a motor and has the advantages of small size and the like.
Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of stepping motor structure.
Background technology
As shown in Figure 1, the stepping motor of prior art is to comprise stator 1, and and stator is concentric and at the two rotor 2, axle 3, left end cap 4, right end cap 5, left bearing 6, the right bearing 7 of a breath are arranged.Existing stepping motor is transported to stator when forming closed magnetic field when the crown of the magnetic line of force by rotor, most of by the stator crown, but also have the sub-fraction magnetic line of force can pass through the stator roller seating space, and the magnetic line of force is by many more few more by the magnetic ditch simultaneously of crown, the torque of motor is big more; Otherwise the torque of motor is more little.
Summary of the invention
The purpose of this utility model be exactly the output torque that improves motor under a kind of situation of same thickness be provided in order to overcome the defective that above-mentioned prior art exists, improve efficiency of motor, stepping motor structure that volume is little.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of stepping motor structure, comprise stator, rotor, axle, left end cap, right end cap, left bearing, right bearing, it is characterized in that, described stator is concentric with rotor, has the gap between the two, and described stator is provided with a plurality of magnetic poles, each magnetic pole is provided with a plurality of stator tooths, stator tooth is provided with the stator roller seating space between any two, is inlaid with the one pole tooth bar in each stator roller seating space, the pole orientation of this one pole tooth bar with its over against the magnetic of rotor core opposite.
Described magnetic pole is 4～12.
Described stator tooth is 4～10.
Described magnetic pole is 8.
Described stator tooth is 6.
Compared with prior art, the utlity model has following advantage:
1, improves the output torque of motor under the situation of same thickness;
2, improve efficiency of motor;
3, save the space.
Description of drawings
Fig. 1 is the structural representation of existing stepping motor;
Fig. 2 is the stator structure schematic diagram of existing stepping motor;
Fig. 3 is a stator structure schematic diagram of the present utility model;
Fig. 4 is the structural representation of the stator rotor of existing stepping motor;
Fig. 5 is the structural representation of stator rotor of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of stepping motor structure, comprise stator 1, rotor 2, axle 3, left end cap 4, right end cap 5, left bearing 6, right bearing 7, described stator 1 is concentric with rotor 2, has the gap between the two, and described stator 1 is provided with 8 magnetic poles, each magnetic pole is provided with 6 stator tooths, stator tooth is provided with the stator roller seating space between any two, is inlaid with one pole tooth bar 8 in each stator roller seating space, the pole orientation of this one pole tooth bar 8 with its over against the magnetic of rotor core opposite.
As Fig. 4, shown in Figure 5, the principle that the utility model repels by homopolarity, because the roller seating space the inside studs with the homopolarity magnetic stripe, therefore thereby the magnetic line of force flows into stator owing to the reason of repelling almost all makes all magnetic lines of force all concentrate by crown and forms closed magnetic field, strengthen the attraction of rotor so greatly, finally reached the effect that increases motor torque.
