This paper presents vector magnetic characteristic analysis by using the complex E&S modelling taking account of stress effect. According to the past researches, we have evaluated the magnetic field strength H vector under controlled stresses and sinusoidal magnetic flux density waveforms. However, it is impossible to control the magnetic flux density B in actually magnetized motor cores. Therefore, it is necessary to know the relationships between B- and H-vector under the controlled stress and the non-controlled magnetic flux conditions. In this paper, we report the measured and calculated relationship between B- and H-vector under stressed conditions and given sinusoidal voltage conditions. The trajectories and parameters of the B- and H-vector under stress, calculated by using the Stress-Complex E&S (SCE&S) modeling, were agreed well with those of the measured B- and H-vector.
