Abstract
The utility model discloses a stepping motor, which is characterized by comprising a stator (3) and end covers (1) arranged at the two ends of the stator (3), wherein the center of each end cover (1) is provided with a bearing (5); the bearing (5) is provided with a rotating shaft (6) with a rotor (4); the inner side face of each end cover (1) is provided with a circular ring boss (2); and the circular ring boss (2) is matched with an inner hole (7) of the stator (3). In the utility model, the inner side of each end cover is provided with the circular ring boss, and the circular ring boss is positioned in combination with the inner hole of the stator, so that the coaxiality between each end cover and the stator is ensured and is basically of zero allowance, the running noise of the motor is lowered, wear is reduced, and the efficiency is improved. The stepping motor also has the characteristic of simple implement structure.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of stepping motor.
Background technology
At present, the external diameter location of end cap and stator is adopted in the end cap of conventional stepping motor and the location of stator, there is following problem in such location structure: the axiality of end cap and stator has double accumulated error, make axiality relatively poor, so that the noise during the motor operation is bigger, loss ratio is more serious, inefficiency.
The utility model content
The purpose of this utility model is, a kind of stepping motor is provided.The utility model can reduce noise, reduces loss and raises the efficiency.
The technical solution of the utility model: a kind of stepping motor is characterized in that: comprise stator and the end cap that is arranged on the stator two ends, the center of end cap is provided with bearing, and bearing is provided with the rotating shaft of band rotor; The medial surface of end cap is provided with the annulus boss, and the annulus boss cooperates with the endoporus of stator.
In the aforesaid stepping motor, described annulus boss cooperates with the endoporus of stator, is the endoporus interference fit of annulus boss and stator.
In the aforesaid stepping motor, described end cap is fixedlyed connected with stator through bolt.
Compared with prior art, the utility model is provided with an annulus boss by the inboard at end cap, the annulus boss cooperates with stator inner hole and positions, thereby guaranteed the axiality of end cap and stator, axiality is zero tolerance substantially, thereby reduced the noise of motor when operation, reduced loss, improved efficient.The utility model also has the enforcement characteristic of simple structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-end cap, 2-annulus boss, 3-stator, 4-rotor, 5-bearing, 6-rotating shaft, 7-endoporus, 8-bolt.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of stepping motor constitutes as shown in Figure 1, it is characterized in that: comprise stator 3 and the end cap 1 that is arranged on stator 3 two ends, the center of end cap 1 is provided with bearing 5, and bearing 5 is provided with the rotating shaft 6 of band rotor 4; The medial surface of end cap 1 is provided with annulus boss 2, and annulus boss 2 cooperates with the endoporus 7 of stator 3; Described end cap 1 is fixedlyed connected with stator 3 through bolt 8.
Reasonable is that described annulus boss 2 cooperates with the endoporus 7 of stator 3, is endoporus 7 interference fit of annulus boss 2 and stator 3.
The utility model is provided with an annulus boss by the inboard at end cap, and the annulus boss cooperates with stator inner hole and positions, thereby has guaranteed the axiality of end cap and stator, axiality is zero tolerance substantially, thereby reduced the noise of motor when operation, reduced loss, improved efficient.
