Purpose. Analysis of the rotor configuration of line start permanent magnet synchronous motor (LSPMSM) when using 3-bar magnet structure with two cases: one with a separating magnetic steel bridge and one without it. Research results allow selecting the appropriate rotor configuration to obtain the best starting characteristics, current, torque, and performance. Thereby, it is possible to replace high efficiency LSPMSM with low efficiency induction motors used in ventilation and water pumping loads to improve the efficiency of electricity use in mining. Methodology. The article uses analytical methods and simulation methods on Ansys/Maxwell software and conducts a laboratory test evaluation to determine the effect of rotor configuration on the starting characteristics, working current, torque ripple, and working efficiency of an LSPMSM for mining applications. Findings. An LSPMSM model was built based on a 15 kW–3,000 rpm induction motor with two rotor configurations: one with a separating magnetic steel bridge and one without it. The results of the study show that when a rotor configuration has no separating magnetic steel bridge, the LSPMSM reaches its maximum speed in 0.45 seconds, a synchronous speed of 3,000 rpm in around 0.75 seconds, a torque ripple of 23.1 %, a current total harmonic distortion of 14.3 %, and a performance of 93.3 %. In contrast, when a rotor structure has a separating magnetic steel bridge, starting the motor is more difficult, taking 1.14 seconds to reach synchronous speed and having a lower starting torque, a current total harmonic distortion of 16.1 %, and a performance of 92.5 %. Originality. Research rotor configurations of LSPMSM based on the 15 kW–3,000 rpm induction motor with and without a separating magnetic steel bridge. The research results allow choosing the appropriate rotor configuration to obtain the best starting characteristics, current, operating torque and performance efficiency. Practical value. The research results are important scientific guidance in the design and manufacture of LSPMSM for application in underground mining to improve the efficiency of electricity use in mining.

Line-start permanent magnet synchronous motors (LSPMSMs) are of great interest to researchers because of their high energy efficiency, due to the growing interest of manufacturers in energy-efficient units. However, LSPMSMs face some difficulties in starting and synchronization processes. The LSPMSM lumped parameter model is applicable to estimating the successfulness of starting and further synchronization. The parameters of such a model can be determined using computer-aided identification algorithms applied to real motor transient processes’ curves. This problem demands significant computational time. A comparison between two algorithms, differential evolution and Nelder–Mead, is presented in this article. The algorithms were used for 0.55 kW, 1500 rpm LSPMSM parameter identification. Moreover, to increase computational speed, it is proposed to stop and restart the algorithms’ procedures, changing their parameters after a certain number of iterations. A significant advantage of the Nelder–Mead algorithm is shown for the solving of the considered problem.

“…According to [3], the efficiency levels from IE1 to IE5 of the motor depend on its power and have a dependency graph, as shown in Figure 1. The rapid development of Neodymium (NdFeB) rare earth permanent magnet technology with high magnetic field density and large energy product has spurred the development of high-efficiency motors, including line start permanent magnet synchronous motor (LSPMSM) [4,5]. LSPMSM is a hybrid between induction and synchronous motors by placing permanent magnets in the rotor of induction motors.…”

Reducing the cost of electricity to improve production efficiency is one of the urgent tasks. Nowadays, the rapid development of Neodymium rare earth (NdFeB) permanent magnet technology has promoted the creation of high-efficiency motors to replace low-efficiency induction motors to save electricity. One of them is a line-start permanent magnet synchronous motor (LSPMSM). The permanent magnet configuration significantly affects the operating characteristics of the LSPMSM, such as working current characteristics, pulsating torque, working efficiency, and starting speed. The content of the article focuses on investigating and evaluating some permanent magnet configurations affecting the working characteristics of the LSPMSM based on the finite element method through Ansys/Maxwell software. The research results are suggested for the design and manufacture of LSPMSM used in mining to save electricity.
