Abstract
The utility model relates to the motor manufacturing field, in particular to a control servo motor which is applied on a financial tool product and is equipped with a magnetic ring and a screening device. The control servo motor is characterized in that a magnetic ring (15) is mounted on a concave portion of a rear cover (10) on the basis of an original motor structure, a plurality of coils which are wounded on the magnetic ring (15) are electrically connected with a control circuit board (12), and are electrically connected with a motor interface, a screening outer cover (4) and a screening rear cover (13) are mounted in the space between a body case (6) and a front base (3) and the space between the body case (6) and a rear base (11), and the screening outer cover (4) and the screening rear cover (13) are engaged and connected. The magnetic ring is mounted to lead electric current of the motor to be stable, and the whole motor is enclosed in the screening device, electromagnetic interference is effectively screened, thereby leading the control servo motor to stably run and resist electromagnetic interference, and the control servo motor can guarantee stable work and prevent electromagnetic interference after being applied on a financial tool product, and leads the work reliability to be improved.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly is applied to the control servomotor that magnet ring and screening arrangement are housed on the financial machine and tool product.
Background technology
Motor in the past, especially be applied in the motor on the financial machine and tool product, because the shielding aspect is perfect inadequately, also because the electric current in the motor is steady inadequately, it is steady inadequately with work to be subjected to electromagnetic interference effect, makes the counting precision of financial machine and tool such as paper money counter can not get guaranteeing fully.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of control servomotor that magnet ring and screening arrangement are housed is provided.
The technical solution of the utility model is the control servomotor that magnet ring and screening arrangement are housed, comprise motor shaft 1, bearing 2, preceding support 3, shielding inner cover 5, casing 6, magnetic shoe 7, rotor 8, commutator 9, bonnet 10, back support 11, control circuit board 12, connecting line 14, it is characterized in that magnet ring 15 being installed, be wound with some turn coil on the magnet ring 15 and be electrically connected with control circuit board 12 and be electrically connected with motor interface at the recess of bonnet 10; Shielding outer cover 4 and shielding bonnet 13 are installed in the space between casing 6 and preceding support 3, back support 11, and shielding outer cover 4 is connected with shielding bonnet 13.
It is round cup shape or mesopore hood-shaped or cylindrical shape or middle boss bottle cap shape or the reel shape or middle indent is hood-shaped or reel shape of cracking that said shielding outer cover 4 has seven kinds of shapes; It is that the center has hole shape or bottle cap shape or center to have projection shape or projection center to have hole shape or cover cavity to have the porose cover cavity again of round spacer ring shape or center to have on round spacer ring shape or the capping hole shape is arranged that said shielding bonnet 13 also has seven kinds of shapes; It is annular or three-back-shaped or clavate that the magnetic core of said magnet ring 15 has three kinds of shapes.
The utility model has the advantages that because magnet ring is housed, make the electric current of motor steady; Because shielding outer cover and shielding bonnet are housed, all be enclosed in the screening arrangement whole motor, effectively electromagnetic interference shield is fallen, thereby make the steady and anti-electromagnetic interference of motor rotation, be applied in and guarantee then on the financial machine and tool product that its stable working prevents electromagnetic interference again, its functional reliability is improved.

Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, support, 12-control circuit board, 13-shielding bonnet, 14-connecting line, 15-magnet ring behind 1-motor shaft, 2-bearing, the preceding support of 3-, 4-shielding outer cover, 5-shielding inner cover, 6-casing, 7-magnetic shoe, 8-rotor, 9-commutator, 10-bonnet, the 11-.As shown, at the recess of bonnet 10 magnet ring 15 is installed, is wound with tens turn coil on the magnet ring 15 and is electrically connected with control circuit board 12 and is electrically connected with motor interface, the effect of magnet ring 15 is to make the electric current of motor obtain filtering, and is more steady during work; Shielding outer cover 4 and shielding bonnet 13 are installed in the space between casing 6 and preceding support 3, back support 11, and shielding outer cover 4 is connected with shielding bonnet 13,, strengthens shielding action, anti-effectively electromagnetic interference the whole containing of motor within it.
With reference to Fig. 2-Fig. 8, Fig. 9-Figure 16, wherein Figure 13 is the cutaway view of Figure 14.In order to cooperate various shielding needs, it is round cup shape or mesopore hood-shaped or cylindrical shape or middle boss bottle cap shape or the reel shape or middle indent is hood-shaped or reel shape of cracking that shielding outer cover 4 is made seven kinds of shapes; It is that the center has hole shape or bottle cap shape or center to have projection shape or projection center to have hole shape or cover cavity to have the porose cover cavity again of round spacer ring shape or center to have on round spacer ring shape or the capping hole shape is arranged that shielding bonnet 13 is also made seven kinds of shapes.
With reference to Figure 17-Figure 19, be three kinds of shapes of magnetic core of magnet ring 15, be respectively annular, three-back-shaped and clavate.Improvement through such makes machine operation more steady, improves motor properties; Also the electromagnetic interference shield inside and outside the machine is fallen, make the precision of motor application in the time improving on the financial machine and tool product in counting.
