“…While symmetrical three-phase short-circuit operation has received some attention in the literature recently [1][2][3][4][5], the available studies of the characteristics of this important class of short-circuit fault remain incomplete. For example, the model developed in [1] only considered the steady-state response that is much less severe than the peak transient response.…”

“…For example, the model developed in [1] only considered the steady-state response that is much less severe than the peak transient response. Closed-form solutions including the impact of prefault currents were introduced in [2][3][4]. However, the effects of magnetic saturation as well as braking torque were not addressed, and the developed analytical expressions were not fully investigated to yield their complete physical insights.…”

This paper investigates the three-phase symmetrical short-circuit characteristics of a permanent magnet synchronous machine (PMSM). Closed-form solutions are derived to predict both the steady-state and transient response of a PMSM to three-phase symmetrical short-circuit (SSC) faults. The developed expressions account for the impact of pre-fault operating conditions and include provisions for incorporating magnetic saturation effects.The influence of machine parameters is studied to identify the key parameters that have a major influence on the steady-state and peak transient values of the fault currents. It is shown that increased inductance saliency ratio, reduced stator resistance, and higher magnetic saturation all increase the peak transient value of the demagnetizing d-axis current. Finite-element (FE) analysis is used to build confidence in the fault current predictions of the developed analytical model.

This paper presents a review of the electromagnetic field and a performance analysis of a radial flux interior permanent magnet (IPM) machine designed to achieve 80 kW and 125 Nm for an electric and hybrid traction vehicle. The motor consists of a 12-slot stator with a three-phase concentrated winding as well as an 8-pole rotor with V-shaped magnets. Selected motor parameters obtained from an IPM prototype were compared with the design requirements. Based on the electromagnetic field analysis, the authors have indicated the parts of the motor that should be redesigned, including the structure of the rotor core, aimed at enhancing the motor's performance and adjusting segmentation for magnet eddy current loss reduction. In addition, iron and PM eddy current losses were investigated. Moreover, transient analysis of current peak value showed that the current may increase significantly compared to steady-state values. A map of transient peak current load vs. torque load plotted against rotor speed was provided. Based on the numeric and analytical results of physical machine parameters, the authors indicate that collapse load during the motor's operation may significantly increase the risk of permanent magnet (PM) demagnetization. It was also found that collapse load increases the transient torque, which may reduce the lifetime of windings.
