“…In contemporary drive systems, electric machines such as synchronous motors (PMSM), brushless DC motors and hybrid stepper motors are used increasingly often [1][2][3]. Currently, even motors with power given in megawatts are manufactured [4]. The development of permanent magnet motors goes hand in hand with the development of the power supply converter and advanced control algorithms.…”

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 disadvantages of asynchronous start-up are high values of the inrush current during the direct line-start process and risk to fail synchronization for loads of high inertia [1,2]. For these reasons, most of the line-start motors have relatively low power, however a high power LSPMSM has been recently reported among others by [3]. Designed line-start synchronous motors should meet the requirements for steady-state operation parameters and requirements related to asynchronous operation, regarding a minimum of: start-up torque, breakdown torque and pull-in torque falling into synchronism [2,[4][5][6][7].…”

“…As a consequence, this may reduce the electromagnetic torque generated by the motor [20]. It is therefore important to correctly design and optimize the magnetic circuit of these machines [21,22] to develop their new structures [3,[23][24][25] in order to obtain the best energy performance.…”

The paper presents research on the development of a line-start synchronous reluctance motor (LSSynRM) and line-start permanent magnet synchronous motor (LSPMSM) based on components of a mass-produced three-phase low-power squirrel cage induction motor (IM). The aim of the research was to modify the squirrel cage rotor structure for which the best functional parameters characterizing the steady state of the LSSynRM and LSPMSM were obtained, while meeting the additional requirements for asynchronous start-up. Field-circuit models of the LSSynRM and LSPMSM have been developed in the professional finite element method (FEM) package, MagNet, and applied in the design and optimization calculations of the considered machines. Experimental testing on the designed LSSynRM and LSPMSM prototypes were carried out. The obtained results were compared with the performance of the reference IM. The conclusions resulting from the comparative analysis of these three motors are given and proposals for further work are discussed.

The paper presents an FE model of coupled electromagnetic and thermal phenomena in Line Start Permanent Magnet Synchronous Motors (LSPMSMs). An algorithm for solving equations of a discrete model using the FEM has been presented. On the basis of this algorithm the author's personally developed software for the analysis of coupled electromagnetic-thermal phenomena in the LSPMS motors was elaborated. This software was used to analyze the start-up process of motors with identical stator and rotor magnetic circuits and different materials of the starting cage. The start-up process of motors with the squirrel-cage made of aluminum and copper was considered. The influence of temperature on the start-up process has been taken into account. The results of simulation tests were compared with the results of measurements.
