“…The two main categories are motor body design optimization and motor control improvement. In the first category, motor design method is proposed to achieve self-sensing capability while retaining the torque-speed capability for PMSM used in a hybrid electric vehicle [11]. By adding a short-circuited rotor-ring into the two-pole slotless permanent-magnet motor, the saliency ratio is expanded to 1.8 [12].…”

Pulsating high frequency voltage injection can be used for sensorless control of SPMSM at zero and low speed ranges. However, the sensorless capability still faces challenges to the requirements of industrial application, especially at heavy load status. Aiming at this issue, this article proposes a sensorless capability expansion method for SPMSM based on inductance parameter identification. First, incremental inductances at d-q-axis and cross-coupling inductance are identified by three steps combining the rotating high frequency voltage injection and pulsating high frequency voltage injection, then, using polynomial curve fitting algorithm, apparent inductances are calculated. Second, positive DC current injection at d-axis is proposed to enhance the saliency ratio based on the analysis of parameter identification results. Compared with the conventional =0 or &lt; 0 method, when positive DC current is injected at d-axis, saliency ratio is enhanced. Third, convergence region is expanded at heavy load status and accuracy of rotor position estimation is improved using the proposed method. Finally, the experiment results validate that the sensorless capability of SPMSM is expanded.

“…IPMSMs provide a high torque density, high reluctance torque, appropriate flux weakening capability, high efficiency and simple controllability [3][4][5]. In some cases, such as traction applications in which IPMSMs are promising electric machines, high torque density and low torque ripple because of the influence on the comfort and the stability of vehicle play a vital role; thus, a trade-off between the average torque and torque ripple should be taken into consideration [6][7][8][9][10]. The developed torque in these machines is intensively affected by the parameters such as magnets size and magnets position [11,12].…”

Sensitivity-Based Optimization of Interior Permanent Magnet Synchronous Motor for Torque Characteristic Enhancement

et al. 2021

This paper presents a multi-objective optimal rotor design for an interior permanent magnet synchronous motor (IPMSM) based on finite element analysis. Due to the importance of torque characteristic in electromagnetic design of IPMSMs, the main efforts of this study are focused on finding a proper trade-off for its torque profile challenges. In this regard, in order to attain high average torque and low torque ripple, the influence of several key factors, such as the permanent magnet (PM) arrangements, PM positions and PM sizes, are examined. Subsequently, according to the outcomes of the performed sensitivity analysis, the appropriate variation interval of the parameters as well as their initial values is determined. Employing such a deterministic optimization algorithm, which does not need large sample points, minimizes the finite element computational cost and leads to accelerate the convergence process. The two-dimensional finite element model (FEM) of an IPMSM is used to perform a sensitivity analysis and establish a multi-objective FEM-based optimization.
