The invention discloses a device for detecting the magnetism of a soft magnetic material in real time under the automatic stress application, which comprises a sample piece to be detected, and also comprises a magnetism applying part which comprises an upper magnetism applying piece and a lower magnetism applying piece which are the same in structure, and the sample piece to be detected is positioned between the upper magnetism applying piece and the lower magnetism applying piece; the number of the clamping pieces is two, the two clamping pieces are located on the two opposite sides of the magnetism applying part, the two clamping pieces are used for clamping the sample piece to be tested, and any clamping piece is stressed through the stress piece; the driving parts are arranged on the other two sides of the magnetic applying part and used for driving the upper magnetic applying part to ascend and descend; the detection piece is arranged on one side, close to the upper magnetic applying piece, of the sample piece to be detected, and the detection piece is in contact with the sample piece to be detected. The automatic applying and real-time measuring device for the stress and the magnetic performance of the large-size flaky soft magnetic material can overcome the defects in the prior art, and is high in precision, small in size, light in weight, stable in performance and capable of being controlled in real time.
Description
technical field [0001] The invention relates to the technical field of magnetic properties and stress measurement, in particular to a magnetic real-time detection device for soft magnetic materials under automatic stress application. Background technique [0002] Due to the small eddy current loss, sheet soft magnetic materials are widely used in large electrical equipment and electromagnetic mechanisms, such as motors, generators, transformers, etc. In practical application, the magnetic properties of sheet-like soft magnetic materials, such as permeability, hysteresis loop, coercive force, etc., will be affected by stress. The source of stress is mostly shear force generated by electrical cutting, assembly and turn The local thrust generated in the process of winding the coil, etc. The magnetic properties of soft magnetic materials affect the operation performance and work efficiency of large electrical equipment, so it is very important to accurately measure the magnetic...
