摘要

车用永磁发电机（PMG）以其高效率、高功率密度和高可靠性而受到越来越多的关注。然而，微弱的主气隙磁场会影响电气设备的输出性能和正常使用。针对这一问题，本文以主气隙磁场的直接影响参数转子磁动势（MMF）为研究对象，详细推导了内置径向永磁体转子磁动力的解析表达式，并在解析表达式中分析了其主要影响因素，包括永磁体钢（PMS）材料，PMS在磁化方向上的厚度、PMS内侧的垂直长度以及PMS的有效计算长度。在此基础上，对转子参数进行了优化，以获得最佳值。然后，对优化后的发电机进行了有限元仿真和样机试验。对比分析结果表明，优化后的转子参数可以有效地提高转子MMF，优化发电机的输出性能。

Analysis of the Rotor Magnetomotive Force of Built-In Radial Permanent Magnet Generator for Vehicle

Permanent magnet generator (PMG) for vehicles has attracted more and more attention because of its high efficiency, high power density, and high reliability. However, the weak main air-gap magnetic field can affect the output performance and the normal use of electrical equipment. Aiming at the problem, this paper took the rotor magnetomotive force (MMF), the direct influencing parameter of the main air-gap magnetic field, as the research object, deduced the analytical expression of rotor MMF of the built-in radial PMG in detail, and analyzed its main influencing factors in analytical expression, including the permanent magnet steel (PMS) material, the thickness of PMS in magnetizing direction, the vertical length of the inner side of PMS, and the effective calculation length of PMS. Based on this, the rotor parameters were optimized to obtain the best values. After that, the finite element simulation and prototype test of the optimized generator were carried out. The comparative analysis results showed that the optimized rotor parameters could effectively improve the rotor MMF and optimize the output performance of the generator.

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
