| Abstract: | Studied the pre-material mole ratio,the compound chemical additive,the granularity and the grain-size distribution,orientation and the influence of agglutinating the temperature to the permanent ferrites material residual magnetism.After the process optimization formula and the craft of using the orthogonal experiment optimizes,the performance of magnetic material had a bigger enhancement to ensure the situation of Hcj >= 230kA/m,residual magnetism Br >= 430mT,which might satisfy the performance requirement of the passenger vehicle’s electrical machinery. |
