“…The PM flux-linkage and the d-and q-axis inductances are simply assumed to be constant, and the influence of magnetic saturation is neglected, i.e., (11) (12) (13) where and are incremental d-and q-axis currents, typically 5% of the rated current.…”

“…the permanent magnets and the armature reaction. In order to determine the influence of cross-coupling on the performance, the nonlinear permeability distribution was determined under a specified load condition, and to enable the d-and q-axis inductances to be subsequently obtained from a linear calculation [11], [12]. However, this approach is not particularly convenient, and indeed is not possible with some commercial finite element (FE) packages, although some of them can do this, such as Jmag and Ansys FE packages.…”

“…In terms of eddy current loss, however, IPMSM with the concentrated winding produces larger eddy current loss of the PM than the distributed winding one. This is because of the wide slot-pitch; the number of stator slot of the concentrated winding model is smaller than the distributed winding one [7]. Therefore, eddy current loss in PM should be considered and reduced when applying the concentrated winding for IPMSM.…”

This study presents the optimized rotor shape of Interior Permanent Magnet Synchronous Motor (IPMSM) with the concentrated winding in order to reduce eddy current loss of Permanent Magnet (PM) and torque ripple under the running condition of Maximum Torque Per Ampere (MTPA) and flux weakening control.Particularly, PM eddy current loss, which is a distinctive loss component in IPMSM, has been numerically investigated with the 3-D Finite Element Analysis (FEA). Associated with the 3-D FEA, the optimal design has been carried out to determine the optimized rotor shape, which contributes to reduce PM eddy current loss and torque ripple without significantly sacrificing the rated torque. The characteristics of the optimally designed rotor shape are compared with the primitive one, manifesting the improved performance, and also thoroughly investigated on the mechanical safety.

“…Furthermore, the problem of impossible self-starting, which had been the biggest weakness of synchronous motor, was resolved by magnetic pole position detection and improved control performance, to the extent that even micro speed control became possible. On the other hand, because the rotor of a motor is connected directly to the mechanical load rotating at high speed, stable stress distribution is essential and it should be designed to fully tolerate critical speed [5][6][7][8][9]. Therefore, an important technology is the structural design of the motor.…”

-Recently, the interior permanent magnet (IPM) motors for electric vehicle (EV) traction motor are being extensively researched because of its high energy density and high efficiency. The traction motor for EV requires high power and high efficiency at the wide driving region. Therefore, it is essential to fully consider the characteristics of the motor from low speed to high-speed driving regions. Especially, when the motor is driven at high speed, a significant centrifugal force is applied to the rotor. Thus, the rotor must be stably structured and be fully endured at the critical speed. In this paper, aims to examine the characteristics of the IPM motor by adjusting the width of air-barrier according to the permanent magnet position which is critical in designing an IPM motor for EV traction motors and to conduct a centrifugal force analysis for grasping mechanical safety.
