Abstract
The utility model discloses a magnetizing device of a magnetic ring, which comprises an iron core and a multi-pole primary coil encircled on the iron core. The magnetizing device of the magnetic ring is characterized in that the outer side of the multi-pole primary coil is additionally provided with another secondary coil generating a magnetic field, and the secondary coil is positioned at the lower part of the iron core. Further, the secondary coil has one turn or a plurality of turns and can be connected with the primary coil in the same direction or in opposite directions in series; and the multi-pole primary coil has at least two poles comprising an N pole and an S pole. The utility model has novel structure, convenient regulation of the width of the poles and high reliability.
Description
Technical field
The utility model relates to the coil clamp technical field that magnetizes, and especially relates to a kind of magnetizing clamp that is used for the transducer magnet ring.
Background technology
Existing ABS velocity transducer magnet ring magnetizes in the process, all magnetic poles is comprised the width difference of the N utmost point and the S utmost point has requirement, Gao Dang vehicle, and this requires just high more.At the coil clamp that magnetizes with common many magnetic poles (refer to be not with secondary coil) when the abs sensor magnet ring is magnetized, after the influence of machining accuracy of getting rid of magnetizing clamp (iron core) to magnet pole widths, the width difference of seeing all N utmost points separately is qualified, the width difference of seeing all S utmost points separately also is qualified, but all N utmost points and the S utmost point are put together this width difference, see that than separately each magnetic pole differs several magnitude, the magnet pole widths of opposed polarity differs bigger, and the effect that magnetizes can not satisfy high-precision requirement.
The utility model content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of magnet ring magnetizer, and it can effectively control the power of all the N utmost points and the S utmost point, and can suitably adjust the width difference of magnetic pole.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of magnet ring magnetizer comprises iron core, is around many magnetic poles in described winding slot of core main coil that magnetizes, and is characterized in that in the diametric outside of described main coil, a certain position of axis direction is provided with another secondary coil that produces the compensating field.
Further, described many magnetic poles main coil the two poles of the earth at least; Described secondary coil is positioned at a certain position of iron core axis, with main coil on same plane or on the top on main coil plane, perhaps in the bottom on main coil plane, be a circle or multiturn, and can with described main coil series aiding connection or differential concatenation.
The distance that many magnetic poles main coil is certain at interval with the secondary coil that increases newly, described secondary coil is positioned at the magnetic field range that described many magnetic poles main coil produces.The magnetic field that described secondary coil produces makes all N pole fields of original many magnetic pole and magnetic fields strengthen or weaken, all S pole fields weaken or strengthen, actual effect is offset the zero magnetic field of original many magnetic pole and magnetic fields, thereby makes the magnet pole widths of all N utmost points and the S utmost point that opposite variation take place.
The utility model changes the distance between described many magnetic poles main coil and the secondary coil by the position of the secondary coil of the above-mentioned increase of adjustment, thereby reaches the purpose of the whole control N utmost point and S utmost point magnet pole widths.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is:
Novel structure, it is convenient to adjust magnet pole widths, helps magnetizing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the end view corresponding with Fig. 1.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
Embodiment, referring to Fig. 1 and Fig. 2,
The utility model is applied to ABS velocity transducer magnet ring and magnetizes, comprise common many pole coils anchor clamps, it is by iron core 3, be surrounded on the main coil 1 of iron core 3, the main coil 1 diametric outside, the position of axis direction is provided with another secondary coil 2 that produces the compensating field, is positioned at the bottom of iron core 3, promptly in the bottom on main coil 1 plane.
Adjust the distance between secondary coil 2 and the main coil 1, reach the purpose of the control N utmost point and S utmost point magnet pole widths.
The utility model not only is used for ABS velocity transducer magnet ring and magnetizes, and also can be used for other similar device and magnetizes.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
