Abstract

With the development of new energy industries, the demand for the driving range and power quality of electric vehicle (EV) drive systems is growing rapidly. The drive motor is faced with the challenge of continuously improving power density and performance. This paper proposes a multiobjective optimization method for an interior permanent magnet synchronous motor for a traction drive (IPMSMTD). Based on the flat wire winding technology, the multiobjective optimization design of the IPMSMTD is carried out to improve the motor power density and high-efficiency range, reduce the torque ripple, and suppress the electromagnetic vibration and noise. The structure and size equation of the IPMSMTD are described. The mathematical model considering iron losses is established, and the optimization objectives are determined. Based on the genetic algorithm, a multiobjective optimization mechanism of the magnetic pole structure is established. The operation performance of the motor is analyzed by the finite element simulation and efficiency map. In order to ensure the comprehensive operation index of the IPMSMTD, the vibration noise and modal analysis are carried out, which verifies the rationality of the designed motor and the optimization method.

利用多目标优化设计和分析用于牵引传动的内部永磁同步电机

随着新能源产业的发展，人们对电动汽车（EV）驱动系统的行驶里程和动力质量的要求也在快速增长。驱动电机面临着不断提高功率密度和性能的挑战。本文提出了一种用于牵引驱动的内部永磁同步电机（IPMSMTD）的多目标优化方法。基于扁线绕组技术，对 IPMSMTD 进行多目标优化设计，以提高电机功率密度和高效率范围，降低转矩纹波，抑制电磁振动和噪声。介绍了 IPMSMTD 的结构和尺寸方程。建立了考虑铁损的数学模型，并确定了优化目标。基于遗传算法，建立了磁极结构的多目标优化机制。通过有限元仿真和效率图分析了电机的运行性能。为了保证 IPMSMTD 的综合运行指标，还进行了振动噪声和模态分析，验证了设计电机和优化方法的合理性。
