Abstract
The utility model discloses a novel stepping motor comprising a rotor structure, a stator core, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are fixed on the front and rear ends of the stator core through bolts; the rotor structure comprises a rotating shaft and magnets sleeved on the rotating shaft, a front bearing is arranged between the front end of the rotating shaft and the centre of the front end cover, a rear bearing is arranged between the rear end of the rotating shaft and the centre of the rear end cover, the novel stepping motor is characterized in that two segments of magnets are arranged, and an annular isolating sleeve is arranged between the two segments of magnets; and the annular isolating sleeve is sleeved on the rotating shaft. According to the rotor structure combination disclosed by the utility model, the integral magnet in the conventional technology is divided into the two segments, and a plastic sleeve having an outside diameter being equal to that of the magnet is arranged between the two segments, thereby reducing the magnet consumption, reducing the weight of the magnets and saving a magnet resource on one hand, and improving the maximal self starting cycle of the motor, improving the electric property of the whole motor and effectively adaptive to a high-speed ball exhibition stand of security and supervisory control on the other hand.
Description
Technical field
The utility model relates to motor device, specifically, relates to a kind of novel stepper motor.
Background technology
In the prior art, stepping motor mainly comprises rotor structure, stator core, is bolted on front end housing and the rear end cap of stator core rear and front end; Rotor structure comprises rotating shaft and is sleeved on magnetite in the rotating shaft, is provided with fore bearing between the front end of rotating shaft and the center of front end housing, is provided with rear bearing between the rear end of rotating shaft and the center of rear end cap.
Stepping motor be a kind of be the actuator of angular displacement with electroporation.Generally, when step actuator receives a pulse signal, it rotates a fixing angle with regard to the rotor structure of Driving Stepping Motor by the direction of setting.The user can come the pilot angle displacement by the control impuls number, thereby reaches the purpose of accurate location.Simultaneously, can also control by the control impuls frequency speed and the acceleration of electric machine rotation, thereby reach the purpose of speed governing.
Existing stepping motor, in the combination of its inner rotator structure, magnetite is sleeved in the rotating shaft, and the magnetic field of the middle part of this magnetite without any effect, has increased inertia that rotating shaft rotates and the attraction of magnetite and stator core to the use of motor on the contrary, magnetic field intensity is large, have influence on the piece electrical characteristic of motor, so that the piece electrical characteristic of motor can't adapt to, simultaneously in the clipping the ball exhibition booth of safety monitoring, because the magnetite material consumption is more, can waste more resource.
Summary of the invention
The technical problems to be solved in the utility model is to overcome defects, the novel stepper motor that provide a kind of and economize on resources, the piece electrical characteristic is high.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of novel stepper motor comprises rotor structure, stator core, is bolted on front end housing and the rear end cap of stator core rear and front end; Rotor structure comprises rotating shaft and is sleeved on magnetite in the rotating shaft, be provided with fore bearing between the front end of rotating shaft and the center of front end housing, be provided with rear bearing between the rear end of rotating shaft and the center of rear end cap, it is characterized in that: described magnetite is provided with two joints, is provided with the ring-type spacer between two joint magnetites; The ring-type spacer is socketed in the rotating shaft.
Say that further the external diameter of described ring-type spacer is consistent with the external diameter of two joint magnetites.
Furtherly, described ring-type spacer is plastic sheath non-magnetic, lightweight.
Owing to adopted technique scheme, compared with prior art, in the rotor structure combination of the present utility model, the magnetite of one in the conventional art is divided into two joints, and in the middle of two joints, a plastic sheath that external diameter is consistent with the external diameter of magnetite is set, like this, the materials of magnetite have been reduced on the one hand, alleviate magnetite weight, saved the magnetite resource, on the other hand, the inertia of rotating shaft rotation and the attraction of magnetite and stator core have been reduced, improved the maximum self-starting cycle of motor, the electrical characteristic of motor integral body gets a promotion, the clipping the ball exhibition booth of more effective adaptation safety monitoring.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Embodiment
Embodiment:
A kind of novel stepper motor as shown in drawings, comprises rotor structure, stator core 7, is bolted on front end housing 3 and the rear end cap 8 of stator core 7 rear and front ends.Rotor structure comprises rotating shaft 1 and the magnetite that is sleeved in the rotating shaft 1, is provided with fore bearing 2 between the center of the front end of rotating shaft 1 and front end housing 3, is provided with rear bearing 9 between the center of the rear end of rotating shaft 1 and rear end cap 8.Described magnetite is provided with two joints, is provided with ring-type spacer 5 between two joint magnetites 4,6, and ring-type spacer 5 is socketed in the rotating shaft.The external diameter of described ring-type spacer 5 is consistent with the external diameter of two joint magnetites.In the present embodiment, what ring-type spacer 5 was selected is plastic sheath non-magnetic, lightweight.
