This paper presents modeling of coreloss resistance for d-q equivalent circuit analysis of IPMSM considering harmonic linkage flux. High efficiency is one of major advantage of IPMSM, therefore precise loss analysis is required for high efficiency design. However, there is practical limitation of d-q equivalent circuit analysis due to harmonic linkage flux especially at high speed region where field weakening control is applied. Harmonic components of linkage flux leads to the underestimation of coreloss. Especially operation with high constant speed power range results in severe underestimate of coreloss. From the presented modeling of coreloss resistance, precise coreloss can be obtained. Verification with FEA and experiments are presented.
