Abstract
The invention relates to the motor manufacture field, in particular to an anti-electromagnetic interference motor characterized in that one layer or multilayer of shielding sleeves (3) cover outside a fixed magnetic tile sleeve (4) in a motor casing (2); a dc motor or an ac motor is arranged in the motor casing (2); the shielding sleeves (3) and the fixed magnetic tile sleeve (4) are movably cooperated. The anti-electromagnetic interference ability of the motor is greatly improved because of the multilayer shielding, especially because the multilayer shielding is adopted by the motor on a currency count machine, the anti-electromagnetic interference is effective, thereby ensuring the currency count precision of the currency count machine.
Description
Technical field
The present invention relates to field of motor manufacturing, particularly anti-electromagnetic interference electric motor.
Background technology
Motor in the past no matter be direct current machine or alternating current machine, is applied on the various machines, owing to there is not shielding properties, can not anti-effectively electromagnetic interference, and particularly on paper money counter, electromagnetic interference is big especially for the counting precision influence of paper money counter.Cause the great attention of respectively producing paper money counter producer, also have some producers to strengthen the shielding measure of motor, but often have only one deck screen that finding in actual use can't anti-fully electromagnetic interference.
Summary of the invention
The objective of the invention is provides a kind of anti-electromagnetic interference electric motor at above-mentioned defective.
Technical scheme of the present invention is an anti-electromagnetic interference electric motor, comprises motor protecgulum 1, electric machine casing 2, fixedly magnetic shoe cover 4, magnetic shoe 5, rotor 6, axle 7 and bearing 8, it is characterized in that fixedly magnetic shoes cover 4 outer one decks that contain in the electric machine casing 2 are to multilayer housing 3.
What install in the said electric machine casing 2 is direct current machine or alternating current machine.
Said housing 3 is movable cooperations with fixing magnetic shoe cover 4.
Advantage of the present invention is that the performance, the especially paper money counter that make motor have anti-fully electromagnetic interference can improve anti-electromagnetic interference capability greatly owing to take multilayer screen in the motor, thereby improves the counting precision of paper money counter.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1,1-motor protecgulum, 2-motor case, 3-housing, 4-be magnetic shoe cover, 5-magnetic shoe, 6-rotor, 7-axle, 8-bearing fixedly.As shown, be to strengthen the shielding of motor, to multilayer housing 3, it is that activity cooperates that housing 3 overlaps 4 with fixing magnetic shoe at fixing magnetic shoe cover 4 outer one decks that contain.Specifically can fixedly outside the magnetic shoe cover 42 layers or 3 layers even multilayer screen cover 3 be installed as required.This shielding measure can be fit to direct current machine or alternating current machine.Thereby improve the anti-electromagnetic interference performance of motor greatly.Especially be applied on the paper money counter, can anti-fully reliably electromagnetic interference, thus improve the counting precision of paper money counter.
Claims (3)
1, anti-electromagnetic interference electric motor, comprise motor protecgulum (1), electric machine casing (2), fixedly magnetic shoe cover (4), magnetic shoe (5), rotor (6), axle (7) and bearing (8), it is characterized in that outer one deck that contains of fixedly magnetic shoe cover (4) in the electric machine casing (2) is to multilayer housing (3).
2, according to the said anti-electromagnetic interference electric motor of claim 1, what it is characterized in that the interior installation of said electric machine casing (2) is direct current machine or alternating current machine.
3,, it is characterized in that said housing (3) and fixing magnetic shoe cover (4) are movable the cooperations according to claim 1 or 2 said anti-electromagnetic interference electric motors.
