“…Therefore, multi-objective genetic algorithm has become one of the highly preferred algorithms in motor design optimization. 13,14 Mutluer 15 used multi-objective genetic algorithm to optimize the design of direct drive external rotor permanent magnet synchronous motor. Chowdhury et al 16 uses GA and Taguchi’s robust design techniques to minimize torque fluctuations while maximizing the average torque of SPMSM at a single operating point.…”

Surface permanent magnet synchronous motor (SPMSM) is widely used in low-speed and high torque permanent magnet synchronous motor. A multi-objective optimization method of hollow shaft direct drive motor (HSDDM) for double direct drive feed system (DDFS) is proposed in this paper. Several dimensions of HSDDM are considered in the proposed design procedure including pole embrace, thickness of magnet, eccentric distance, and air gap length. A multi-objective optimization model is established to minimize cogging torque, maximize efficiency, and minimize the magnet weight. The Optimized Latin hypercube sampling (OLHS) is used to design the experimental samples, and the sampling results are calculated by the finite element method (FEM). The Kring approximate model is established according to the sampling results. Based on the established approximate model, NSGA II multi-objective genetic algorithm is used to optimize the HSDDM. Compared with that before optimization, the efficiency after optimization is increased by 4.08%, the cogging torque is reduced by 86.78%, and the magnet weight is reduced by 20.24%. Eventually, the integration of NSGA-II and FEM provides an effective approach to obtain the optimal design of HSDDM.

“…Although NSGA-Ⅱalgorithm had strong global search ability, its computation time was long and its efficiency is low. In literature [14], NSGA-III algorithm was used to optimize the efficiency and cost of the motor. Although the NSGA-III algorithm had high convergence, it still faced high computational complexity when dealing with high-dimensional problems.…”

In order to improve the output torque, suppress the torque ripple, and reduce the usage of permanent magnets when applying the external rotor permanent magnet synchronous motor (ERPMSM) as a belt conveyor drive motor, this paper proposed a multi-objective optimization method for ERPMSMs based on the enhanced multi-objective whale algorithm (E-MOWOA), parameter stratification and response surface methodology (RSM). Firstly, a finite element simulation model of the motor was established, and parameter stratification was carried out through Spearman correlation analysis to screen out the layer 1 and layer 2optimization parameters. Secondly, various improvement strategies were introduced for the traditional whale algorithm, and an E-MOWOA improvement strategy was proposed. The effectiveness of the algorithm improvement was verified through algorithm performance testing. Then the multi-objective optimization of parameters were carried out. For the layer 1 optimization parameters, the response surface method was adopted to establish a response surface model, provide regression equations, and use E-MOWOA for iterative optimization. For the layer 2 optimization parameters, parameterized scanning was used for optimization. Finally, a comparative analysis of the optimization effect was conducted through finite element simulation experiments and prototype experiments. The experimental results showed that after optimization, the average output torque of the motor was increased by 4.19%, the cogging torque was reduced by 22.92%, the torque ripple was reduced by 31.34%, the amplitude of the no-load back electromotive force fundamental wave was increased by 13.39%, and the cost of the permanent magnet was reduced by 7.83%, which verified the effectiveness and feasibility of the proposed method.

Permanent Magnet (PM) Brushless Direct Current (BLDC) actuators/motors have many advantages over conventional machines, including high efficiency, easy controllability over a wide range of operating speeds, etc. There are many prototypes for such motors; some of them have a very complicated construction, and this ensures their high efficiency. However, in the case of household appliances, the most important thing is simplicity, and, thus, the lowest price of the design and production. This article presents a comparison of computer models of different design solutions for a small PM BLDC motor that uses a rotor in the form of a single ferrite magnet. The analyses were performed by using the finite element method. This paper presents unique self-defined parts of basic PM BLDC actuators. With their help, various design solutions were compared with the PM BLDC motor used in household appliances. The authors proved that the reference device is the lightest one and has a lower cogging torque compared to other actuators, but also has a slightly lower driving torque.
