According to the reduction for efficiency of high-speed permanent magnet brushless DC motor (High-speed PM BLDC motor) by core loss of stator in the design process, the accurate calculation for stator core loss is very important.2-D finite element method is used to analyze the alternating magnetic field and magnetic field of the stator core of which a rotational speed of 27000rpm high-speed BLDC motor. Harmonic analysis is used for the step magnetic field of high-speed BLDC motor, Based on the model of Bertotti iron loss calculation, superposition of various frequency loss will be calculated, the calculation accuracy was validate to increase.

Magnetic pulse welding is a high-speed welding technology, which is suitable for welding light metal materials. In the magnetic pulse welding system, the field shaper can increase the service life of the coil and contribute to concentrating the magnetic field in the welding area. Therefore, optimizing the structure of the field shaper can effectively improve the efficiency of the system. This paper analyzed the influence of cross-sectional shape and inner angle of the field shaper on the ability of concentrating magnetic field via COMSOL software. The structural strength of various field shapers was also analyzed in ABAQUS. Simulation results show that the inner edge of the field shaper directly affects the deformation and welding effect of the tube. So, a new shape of field shaper was proposed and the experimental results prove that the new field shaper has better performance than the conventional field shaper.
