Description
Technical field
The present invention relates to a kind of magnetic field measurement instrument, especially, is a kind of pulsating field detector.
Background technology
Monopole asynchronous motor, after passing into single-phase alternating current, can produce impulsive magnetic field in single-phase AC winding, and when the size and Orientation along with electric current changes, the size in magnetic field and polarity can and then change, but constant all the time in the position in space.Existing magnetic field detection technology, major part all utilizes detecting instrument from magnetic field external detection, owing to being all position magnetic direction with artificial experience, therefore locates inaccurate, causes testing result out of true.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of pulsating field detector, this pulsating field detector can put into inside, magnetic field, and automatic calibration coil and magnetic field position keep orthogonal, precisely detects the size in magnetic field.
The technical solution adopted for the present invention to solve the technical problems is: this pulsating field detector comprises coil, gyroscope, detection display circuit; Described gyroscope comprises rotor axis body, rotor rotating disk, inner ring, outer shroud, supporting ring and base; Described coil winding is in the rotating disk surrounding of described gyrowheel, and the axis body of described gyrowheel is made up of soft magnet; Described detection display circuit is connected with described coil.
As preferably, the rotating disk of described gyrostatic rotor, inner ring, outer shroud, supporting ring and base are plastic material, described outer shroud is connected by screwing rotating shaft with described supporting ring, described inner ring and described outer shroud are also connected by screwing rotating shaft, described gyrostatic supporting ring and base, utilize nut to be fixedly connected with.
As preferably, the two ends of described gyrostatic base are provided with folder cover buckle.
As preferably, described detection display electricity routing amplifier and gauge outfit composition.
Beneficial effect of the present invention is: above-mentioned pulsating field detector, detector is put into pulsating field, the rotor axis body be made up of soft magnet is magnetized, thus make axis body be parallel to magnetic direction, and due to the coil plane on rotating disk orthogonal with axis body, so coil can be located automatically, remain orthogonal with magnetic direction, precisely detect magnetic field.
Accompanying drawing explanation
Fig. 1 is the structural representation of this pulsating field detector.
Fig. 2 is the detection display circuit diagram of this pulsating field detector.
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, comprise coil 1, gyroscope 3, detection display circuit 5, described gyroscope 3 comprises rotor axis body 2, rotor rotating disk 12, inner ring 33, outer shroud 32, supporting ring 31 and base 4.Described coil 1 is wrapped in rotating disk 12 surrounding of described gyroscope 3 rotor, the axis body 2 of described gyroscope 3 rotor is made up of soft magnet, rotor axis body is placed in magnetic field, after being magnetized, rotor axis body is parallel with pulsating field direction, described coil 1 is orthogonal with the locus of described rotor axis body 2, thus described coil 1 can keep orthogonal with the locus in pulsating field direction.
The rotating disk 12 of described gyroscope 3 rotor, inner ring 33, outer shroud 32, supporting ring 31 and base 4 are plastic material, and plastics do not affect Distribution of Magnetic Field, thus can not affect the accuracy of detection.
Described outer shroud 32 is connected by screwing rotating shaft 34 with described supporting ring 31, described inner ring 33 and described outer shroud 32 are also connected by screwing rotating shaft 34 ', thus after gyroscope 3 position stability, rotating shaft 34,34 ' can be screwed, the locus of fixed rotor, inner ring 33, outer shroud 32, support 31 by tightening.
Supporting ring 31 and the base 4 of described gyroscope 3, utilize nut 35 to be fixedly connected with.
The two ends of the base 4 of described gyroscope 3 are provided with folder cover buckle 41, and folder cover buckle 41 can clamp the limit end of stator core, thus the fixing position of gyroscope 3 in pulsating field.
Described detection display circuit 5 is connected with described coil 1, and described detection display circuit 5 is made up of amplifier 51 and gauge outfit 52, thus the small induction electromotive force that coil produces can amplify by amplifier 51, and gauge outfit 52 reading is more accurate.
Above-mentioned pulsating field detector, puts into impulsive magnetic field by detector, utilizes folder cover buckle 41 to clamp stator core limit end, fixes the locus of gyroscope 3 in magnetic field.After entering magnetic field, the rotor axis body 2 be made up of soft magnet is magnetized, the magnetic field force that rotor axis body 2 is subject to pulsating field attracts, inner ring 33, the outer shroud 32 of drive gyroscope 3 rotate together, when the direction of magnetization of soft magnet is identical with pulsating field direction, rotor axis body 2 is still on the position parallel with magnetic direction, and because coil 1 is orthogonal with rotor axis body 2, therefore coil 1 is orthogonal with the direction of pulsating field.Now by the connection outer shroud 32 of gyroscope 3, the screwed rotating shaft 34 ' of inner ring 33 and be connected outer shroud 32, the screwed rotating shaft 34 of supporting ring 31 tightens fixing, the each several part locus of gyroscope 3 fixes, connect detection display circuit 5, the pulsating field of change makes to produce induction electromotive force in coil 1, by detection display circuit 5, less electric potential difference is exaggerated through amplifier 51, and gauge outfit 52 reading is more accurate, according to parameter in gauge outfit 52, calculate magnetic field size.
