“…Their aim is to improve the functional parameters, characteristics and economic indicators, i.e., to reduce production and operational costs. The new designs are often more difficult to construct technologically [5]. Therefore, powder technology, which 2 of 11 consists of manufacturing soft magnetic materials and forming permanent magnets, is used very often [9].…”

The paper presents the optimization method and computer software for the design of a low-power line-start permanent magnet synchronous motor (LSPMSM). The in-house-developed computer software was created with two independent modules: (a) the optimization procedure and (b) the numerical model of the motor. The optimization procedure used was a metaheuristic optimization method based on the gray wolf algorithm. Four design variables linked to the rotor structure were selected. The optimization process was performed from the rotor of a low-power induction motor (IM). The prototype of the motor (LSPMSM) was then built. The experimental measurements were performed for base the IM and optimized LSPMSM. The results of the measurements were compared for both motors. The experimental results confirmed the better performance of the designed motor in comparison to the induction motor.

“…The strengthened starting and synchronising abilities by applying the composite solid rotor to the LSPMSM have been validated through a few comparative types of research [17, 18]. Results of these researches showed that under the given load conditions, only the LSPMSM equipped with the composite solid rotor succeeded in the synchronising while LSPMSMs with other rotors failed.…”

This study conducts a deep research on a line-start permanent-magnet synchronous motor (LSPMSM) with a composite solid rotor through detailed analyses of two sets of intrinsic motor parameters, i.e. (i) the flux linkages stemming from permanent-magnet (PM) poles, or the so-called PM flux linkages, and (ii) the magnetising inductances related to the stator-rotor magnetic couple. The analyses proceed by separating the motor starting process into a series of sub-states with different slips. At each sub-state, the PM flux linkages and magnetising inductances are both susceptible to the varying saturation of motor cores and hence perform as time-dependent quantities alternating exactly in the slip frequency. Accordingly, these parameters are determined as combinations of cosine functions indicating the quantity alternation, by which the rotor resistances and selfinductances are obtained at the same time. Assembly of all the confirmed motor parameters generates an analytical model of the studied LSPMSM. Responses of this model stay totally in good agreement with those from the finite-element method, and the close result correlation offers an effective validation of the analyses presented in this work.
