Abstract：With the expansion of the market of new energy vehicles，the working eficiencyof the motor has received extensive atention.Focusing onthe enginering application of pre-coated silicon steel sheets to manufacture stator cores of motors，the influence of bonding parameters on the mechanical and magnetic properties of stator cores was explored，and the eddy current losses under different parameters were numerically simulated.Compared with the welding process，the pull-out force was increased by 388.26% ，and the bonding process showed beter mechanical properties.At the same time，dueto the significant increase in hysteresis loss and eddy current loss of the iron core caused bythe weld，the iron losscaused bythe welding processincreased significantly.Compared with the welding process，the iron loss of the bonded sample was reduced by 27.60% and 26.58% respectively under the conditions of 2.7μm and 3.55μm coating thickness and the magnetic properties showed good performance.The iron loss of the stator core made bythe bonding process decreased with the increase of the lamination pressre.Compared with the 85 N stacking pressure，the iron loss of the stator core made by the bonding process decreased by 0.75% and 1.91% under the pressure of 210N and 420N ，respectively.
