Phenolic resin for powder, and is easy to be mixed with the ferromagnetic components to make the ferromagnetic crystal grain electrical and mechanical resistance. And then will get the soft magnetic alloy mixture for preparation for characterization of disc samples, 18; Have considered the two variables: the percentage of the phenolic resin adhesive ( 0. 2 - 0. 5 - 0. 75 - 1 - 1. 5 - 2) And cylindrical mold pressure ( 400 - 500 - 600 - 700 MPa) 。 Then put the disc under 150 ° C for 30 minutes subnetted processing, get prepared by mechanical polishing winding for electromagnetic testing ring samples, 23, 24. From powder to the circular, synthesized the various stages of production process. Also prepared samples for mechanical testing. In code sample classification, this code report about the types of resin ( Phenolic resin P) , the weight percentage of plastic adhesive and compaction pressure ( In MPa) The information; For example, the 'P - 1 - 700 'logo is under pressure from 700 MPa with 1% weight percentage of phenolic resin torus. The description of the magnetic properties using the well-known 'transformer method', two of the winding coil on the annular core: winding with magnetic field H is proportional to the current to magnetic circuit, winding is implemented by a relatively thin copper wire, the copper wire is wound around the magnetic core, and testing and magnetic flux density B is proportional to the induced voltage. Power supply and measuring system is designed in our laboratory. Usually requires the sinusoidal waveform is achieved through the converter, the converter on the output side has a filter, in order to protect the low harmonic content. In our case, sinusoidal power is by means of linear amplifier ( To make it cheaper) Implementation, the total harmonic distortion ( THD) Less than 1%; Data acquisition board, powered by LabView code to automatically collect data and processed to obtain the magnetic information.
