Equipment for detecting magnetic flux of magnetic element

Abstract

The invention discloses equipment for detecting magnetic flux of a magnetic element. The equipment comprises a supporting frame, an object table which is fixed on the supporting frame, and an electronic scale and an iron block which are arranged exactly below the object table. The object table is prepared by non-magnetic-conductive material. The upper surface and the lower surface of the object table are horizontal planes. The iron block is placed on the electronic scale. The upper surface and the lower surface of the iron block are horizontal planes. A segment of gap is reserved between the upper surface of the iron block and the lower surface of the object table. Advantages are that the magnetic flux of the magnetic element is presented by the numerical value of the electronic scale, and an operator can judge qualification of the magnetic flux of the magnetic element according to the numerical value of the electronic scale only by placing the magnetic element to be detected on the object table so that operation is easy, qualification of the magnetic flux is presented by the numerical value of the electronic scale without interference of external factors, and thus test precision is relatively high.

Description

technical field [0001] The invention relates to a detection device, in particular to a device for detecting the magnetic flux of a magnetic element. Background technique [0002] With the development of science and technology, more and more magnetic components are applied to various fields. In order to ensure the quality of the magnetic components, after the production of the magnetic components is completed, it is necessary to check whether each important parameter (such as magnetic flux) is within the qualified range. [0003] Existing devices for measuring magnetic flux generally include a flux coil (Helmholtz coil) and a fluxmeter, and the flux coil and the fluxmeter are connected. When testing the magnetic flux, turn on the fluxmeter, put the magnetic element into the flux coil first, then take the magnetic element out of the flux coil and keep it away from the flux coil for a certain distance, the fluxmeter will test the magnetic element magnetic flux and output thro...

AI Technical Summary

Problems solved by technology

However, the existing equipment for measuring magnetic flux has the following problems: first, the magnetic element needs to be placed in the magnetic flux coil and then away from the magnetic flux coil to complete a detection process, and the operation is more complicated; second, the magnetic element is theoretically far away from the magnetic flux coil The farther the distance is, the higher the accuracy of the test data of the magnetic flux tested by the fluxmeter is, but in actual production, in order to ensure the efficiency of the test, the distance between the magnetic element and the flux coil is determined, and this distance will not be too large. This magnetic component will interfere with the test of the fluxmeter, so that the accuracy of the test data of the magnetic flux is not high
