“…The main goal of this multi-objective optimization is to maximize the average torque, followed by minimizing torque ripple as a secondary objective. Therefore, in order to obtain higher average torque and lower torque ripple, the optimized objective functions can be defined using Equations ( 4) and ( 5), as shown in Equation (6).…”

“…At the moment, by applying high-performance permanent magnet material, NdFeB, the torque and efficiency of permanent magnet motors have been significantly improved [3,4]. But due to the significant fluctuations and high prices of NdFeB, and NdFeB materials being non-renewable resources, their reserves are decreasing year by year with continuous mining [5,6]. Permanent magnet-assisted synchronous reluctance motors (PMA-SynRMs) typically have fewer permanent magnets for the same volume than conventional permanent magnet synchronous motors.…”

Permanent magnet-assisted synchronous reluctance motors (PMA-SynRMs) are widely used in various industries as a relatively inexpensive and high-performance energy conversion device. The model proposed in this article relies on a magnetic pole-biased permanent magnet synchronous reluctance motor with a magnetic focusing effect. Two types of models with Halbach array and magnetic focusing effect have been proposed, which increase excitation and make the internal magnetic circuit of the rotor more saturated, thereby achieving higher electromagnetic torque. Through finite element simulation analysis and verification, the motor characteristics of the basic and proposed permanent magnet-assisted synchronous reluctance motor were calculated, including the air gap flux density and back electromotive force (EMF) in no-load analysis, as well as the average torque, torque ripple, and efficiency in load analysis. In addition, multi-objective optimization was also conducted on the rotor topology structure of proposed model two, using the uniform Latin hypercube sampling method to uniformly sample the data samples and the Pearson correlation coefficients to perform a sensitivity analysis on the data. The pilOPT multi-objective autonomous optimization algorithm was used to perform multi-objective autonomous optimization on parameters with high correlation, and the best-found solution based on the Pareto front was selected. Compared with proposed model two, the average torque of the optimized model increased by 18.14%, the efficiency increased by 1.05% and the torque ripple decreased by 5.22%. Finally, the anti-demagnetization performance of the optimized model’s permanent magnet was analyzed.
