Abstract
The utility model relates to the motor technical field and particularly relates to a stepping motor rotor structure used for security monitoring. The rotor structure comprises a rotating shaft and loadstone connected through a shaft sleeve; the shaft sleeve is sleeved on the rotating shaft; and the loadstone is sleeved on the shaft sleeve. In the rotor structure, the loadstone is hollowed out in the center and is connected with the rotating shaft through the shaft sleeve, so that ineffective magnetic field generated by the ineffective loadstone in the center of the loadstone is reduced, and so-caused influence on the electric characteristics of the motor is reduced; besides, loadstone material consumption is lowered compared with the traditional rotor, so that resource is saved on one hand, and both the inertia of the rotation of the rotating shaft and the attractive force between the loadstone and an iron core of a casing are reduced on the other hand, accordingly, the Max starting frequency of the motor is improved, the overall electric characteristics of the motor are improved, and the rotor structure can adapt to a high-speed ball show stand for security monitoring more effectively.
Description
Technical field:
The utility model relates to technical field of motors, relates in particular to a kind of stepping motor rotor structure that is used for safety monitoring.
Background technology:
Stepping motor is a kind of actuator that electric pulse is converted into angular displacement.More popular saying: when step actuator receives a pulse signal, it rotates a fixing angle (being step angle) with regard to the drive stepping motor rotor structure by the direction of setting.The user can come the pilot angle displacement through the control impuls number, thereby reaches the purpose of accurate location; Can also control speed and the acceleration that motor rotates through the control impuls frequency simultaneously, thereby reach the purpose of speed governing.At present; Be used for the diameter 10mm stepping motor (motor) of safety monitoring, its electrical characteristic mainly contains: maximum self-starting cycle (Max starting frequency), maximum continuous respond cycle (Max.slewing frequency), introduce moment (Pull-in torque), deviate from moment (Pull-out torque).In the inner rotator textural association of motor; As shown in Figure 1, magnetite 20 is socketed in the rotating shaft 10, and the use of the 20 pairs of motors in magnetic field of the middle part of this whole magnetite 20 has no use; It has increased the inertia of rotating shaft 10 rotations and the attraction of magnetite 20 and casing iron core on the contrary; Magnetic field intensity is big, has influence on the piece electrical characteristic of motor, makes the whole opering characteristic of electric apparatus of motor in the clipping the ball exhibition booth of safety monitoring, to adapt to; Because the magnetite material consumption is more, the waste resource is unfavorable for energy-conservation theory simultaneously.
The utility model content:
The purpose of the utility model is exactly the deficiency that exists to prior art and provide a kind of and economize on resources, promote the stepping motor rotor structure of motor piece electrical characteristic.
To achieve these goals, the technical scheme of the utility model employing is:
The stepping motor rotor structure, it includes rotating shaft, magnetite, is connected through axle sleeve between magnetite and the rotating shaft, and axle sleeve is socketed in the rotating shaft, and magnetite is socketed on the axle sleeve.
Said magnetite is two joints, and two joint magnetites are socketed on the axle sleeve side by side.
The circumferential outer surface at said axle sleeve middle part convexes with ring-shaped step, and two joint magnetites lay respectively at the both sides of ring-shaped step.
The external diameter of said ring-shaped step is consistent with the external diameter of magnetite.
The utility model beneficial effect is: the utility model includes rotating shaft, magnetite, is connected through axle sleeve between magnetite and the rotating shaft, and axle sleeve is socketed in the rotating shaft; Magnetite is socketed on the axle sleeve, and the utility model carries out in the magnetite centre that part is emptied and connects rotating shaft through axle sleeve, reduces the invalid invalid magnetic field that magnetite produced, magnetite centre; Reduction is to the influence of motor electrical characteristic; And on the magnetite basis of conventional rotors, reduced the magnetite materials, alleviated the weight of magnetite, economized on resources on the one hand; The inertia of rotating shaft rotation and the attraction of magnetite and casing iron core have been reduced on the other hand; Improve the maximum self-starting cycle of motor, promoted the whole electrical characteristic of motor, the clipping the ball exhibition booth of more effective adaptation safety monitoring.
Description of drawings:
Fig. 1 is the topology view of existing stepping motor;
Fig. 2 is the topology view of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Figure 2, the stepping motor rotor structure, it includes rotating shaft 1, magnetite 2, is connected through axle sleeve 3 between magnetite 2 and the rotating shaft 1, axle sleeve 3 is socketed in the rotating shaft 1, magnetite 2 is socketed on the axle sleeve 3.The utility model carries out in magnetite 2 centres that part is emptied and connects rotating shafts 1 through axle sleeve 3; Reduce the invalid magnetic field that the invalid magnetite 2 in magnetite 2 centres is produced, reduce influence, and on magnetite 2 bases of conventional rotors, reduced magnetite 2 materials the motor electrical characteristic; Alleviated the weight of magnetite 2; Economize on resources on the one hand, reduced the inertia of rotating shaft 1 rotation and the attraction of magnetite 2 and casing iron core on the other hand, improved the maximum self-starting cycle of motor; Promoted the whole electrical characteristic of motor, the clipping the ball exhibition booth of more effective adaptation safety monitoring.
Magnetite 2 is two joints, and two joint magnetites 2 are socketed on the axle sleeve 3 side by side, and two-segment type magnetite 2 has reduced the use amount of magnetite 2 more, more can economize on resources.The circumferential outer surface at axle sleeve 3 middle parts convexes with the both sides that ring-shaped step 31, two joint magnetites 2 lay respectively at ring-shaped step 31.The external diameter of ring-shaped step 31 is consistent with the external diameter of magnetite 2.
Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
