Description
Technical field
The utility model relates to a kind of reduction electromagnetic interference and radiation appliance, and especially a kind of reduction micromachine electromagnetic interference (EMI) emissions device belongs to the technical field that micromachine is controlled.
Background technology
Along with the continuous development of circuit breaker industry, circuit breaker is miniaturization more and more, intellectuality, used instrument and meter is more and more accurate, this to circuit breaker the utilization on motor also have higher requirement.Especially the standard to developed countries such as America and Europe outlets is more and more higher, and it is more and more littler to require the electromagnetism pair of motor to penetrate, thereby satisfies the demand of accurate wiring board and precision instrument.But according to the national conditions of present China, also have no small gap with developed country aspect the motor electromagnetic radiation, a lot of motors can not satisfy outlet, do not reach the requirement of precision instrument.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reduction micromachine electromagnetic interference (EMI) emissions device is provided, and it is simple in structure, can reduce the electromagnetic radiation of motor, and is safe and reliable.
According to the technical scheme that the utility model provides, described reduction micromachine electromagnetic interference (EMI) emissions device comprises motor and is positioned at power line on the motor; Some magnet reducing blocks are set on the described power line, and power line passes magnet reducing block corresponding to the other end that links to each other with motor, and the housing of described magnet reducing block and motor fixes.
Described magnet reducing block fixes by the housing of adhesive glue and motor.Described magnet reducing block is an annular.Described magnet reducing block is ferrite Y30BH.Described power line links to each other with power supply corresponding to the other end that links to each other with motor.Described magnet reducing block is at least two.
Advantage of the present utility model: two magnet reducing blocks are set on the power line at least, and magnet reducing block is ferrite Y30BH; Magnet reducing block is fixed by the housing of adhesive glue and motor; When power line linked to each other with power supply, magnet reducing block can filter the electromagnetic field that electric current produces, and reduces the magnetic field that electric current produces, thereby reduces the electromagnetic radiation of motor, and was simple in structure, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
The utility model comprises power line 1, magnet reducing block 2, adhesive glue 3 and motor 4.
As shown in Figure 1: motor 4 is provided with power line 1, and described power line 1 is used for motor 4 is linked to each other with external power source, for motor provides energy.When power line 1 and external communications, the electric current in the power line 1 will produce electromagnetic interference.In order to reduce the electromagnetic interference that flows through electric current in the power line 1, at least two magnet reducing blocks 2 are set on power line 1, described magnet reducing block 2 is a circular ring structure, forms magnet ring; The ferrite Y30BH of magnet reducing block 2 for not magnetizing.Power line 1 passes magnet reducing block 2 corresponding to the other end that links to each other with motor 4, and magnet reducing block 2 is enclosed within on the power line 1.Magnet reducing block 2 is fixed on by adhesive glue 3 on the shell of motor 4, and the shell of motor 4 is an arc, and magnet reducing block 2 is fixed on the shell of motor 4 corresponding to the side that arc is arranged.Adhesive glue 3 is powerful structure glue, has guaranteed the bonding strength of magnet reducing block 2 with motor 4.
As shown in Figure 1: during work, be with at least two magnet reducing blocks 2 on the power line 1, power line 1 links to each other with external power source corresponding to the other end that links to each other with motor 4.When motor 4 work, will flow through electric current in the power line 1, the electromagnetic field that magnet reducing block 2 will filter current produces reaches the purpose that reduces electromagnetic interference; Be suitable for the motor of the power line 1 external accurate wiring board of motor 4, have electromagnetic protection effect preferably.
Two magnet reducing blocks 2 are set on the utility model power line 1 at least, and magnet reducing block 2 is ferrite Y30BH; Magnet reducing block 2 is fixed by the adhesive glue 3 and the housing of motor 4; When power line 1 linked to each other with power supply, magnet reducing block 2 can filter the electromagnetic field that electric current produces, and reduces the magnetic field that electric current produces, thereby reduces the electromagnetic radiation of motor 4, and was simple in structure, safe and reliable.
