Webthe accuracy ofthe model. The core loss or iron loss, caused by the permanent magnet (PM) flux and armature reaction flux, is a significant component in the total loss ofa PMSM, and thus, it can have a considerable effect on the PMSM modeling and performance prediction. This paper proposes a model ofPMSM taking into account the stator core losses. WebIn a conventional method using an equivalent circuit, the output torque calculation has several steps: 1) calculate the PM torque, 2) calculate d-axis inductances, 3) calculate q- axis inductance, 4) estimate the reluctance torque, 5) add the PM and reluctance torque [1], [4]–[6], and [8]–[9].
