The utility model has the advantages that; Because insulating coating is installed, help the insulation of motor on the one hand, a large amount of metal materials has been saved in the aspect in addition, has reduced the volume of motor, has reduced cost simultaneously.Because magnet ring is housed, electric current there is filter action, make the electric current of motor steadily reliable, therefore when work, more stable, especially be contained on the financial machine and tool product, improve job stability, and the electromagnetic interference of the magnetic head on the paper money counter is had obvious decline effect; Because multilayer screen outer cover and a plurality of shielding bonnet are housed, strengthened shielding construction, thereby the paper money counter anti-electromagnetic interference capability is strengthened, further improve the counting precision.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2-Fig. 4 is three kinds of shape schematic diagrames of magnetic core of magnet ring.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1,1-motor shaft, 2-bearing, 3-protecgulum overcoat, 4-shielding outer cover, 5-shielding inner cover, 6, casing, 7-magnetic shoe, 8-rotor, 9-commutator, 10-bonnet, 11-bonnet overcoat, 12-control circuit board, 13-shielding bonnet, 14-connecting line, 15-components and parts.The winding wire diameter of said rotor 8 is φ 0.06-φ 0.12mm, and umber of turn is the 180-300 circle, and the external diameter of rotor 8 is φ 30-φ 44mm, and the groove number is 12 grooves, and the width of rotor is 18-42mm; The external diameter of commutator 9 is φ 11-φ 21mm, and the groove number is 24 grooves; The thickness of magnetic shoe 7 is 3-12mm, as shown, innovative point of the present utility model is all to be installed in all parts of whole motor core in the insulating coating, insulating coating comprises protecgulum overcoat 3 and bonnet overcoat 11, protecgulum overcoat 3 is taked gluing being fastenedly connected with bonnet overcoat 11, and insulating coating employing plastic material such as nylon 66 material are injection molded.Be provided with bearing pedestal in the protecgulum overcoat 3, the bearing 2 on the motor shaft 1 can be installed.Can save a large amount of metal materials so on the one hand, help the insulation of motor simultaneously, processing technology has also been simplified in the aspect in addition, has dwindled the volume of motor, and what is more important reduces cost.Magnet ring also is installed, and the power line that is wound with on the magnet ring on some coils and the connecting line 14 is electrically connected in series, be for electric current steadily, strobe, and the electromagnetic interference to magnetic head has obvious decline effect in paper money counter.Another innovative point is to be inclusive with shielding outer cover 4 and shielding bonnet 13 in the outside of shielding inner cover 5, and shielding outer cover 4 is connected with shielding bonnet 13, and shielding bonnet 13 is connected with bonnet overcoat 11.It is that movable cooperation or tight fit are connected that shielding outer cover 4 is connected with shielding bonnet 13; It is that movable cooperation or tight fit are connected that shielding bonnet 13 is connected with bonnet overcoat 11; On this basis, also can add one deck shielding outer cover outside shielding outer cover 4 and add a shielding bonnet, its relation of being connected constitutes multilayer screen outer cover and a plurality of shielding bonnet with above-mentioned the same.Fall if the inside and outside electromagnetic interference of motor machine can't be finished conductively-closed, then can consider to add one deck again in the outside of 2 layers of shielding outer cover, simultaneously, the shielding bonnet also correspondingly adds one again.Until electromagnetic interference is masked fully, guarantee the counting precision of paper money counter.The shielding outer cover is rolled into tubular with sheet metal, is rolled into as a thin plate, therefore leaves the centre joint, becomes the opening tubular; Also can be rolled into multilayer, just not have the centre joint, become reel shape with thin plate.
