首先基于传统的电机本体设计方法,获得一台15 kW、102 V的内嵌式永磁电动机的基本设计参数,然后利用基于等效磁路法的RMXPRT软件对该内嵌式永磁电动机的一些重要设计参数进行优选,得到较为理想的参数范围。最后,引入一种新颖的优化方法——田口法,以内嵌式永磁电动机的气隙长度、永磁体厚度与宽度、磁桥长度和宽度作为优化变量,以效率和磁钢用量作为优化目标对电机进行优化设计。确定最优方案后将其导入到电磁场有限元分析软件Maxwell进行仿真,以对所设计电机进行合理性分析。优化后效果明显,对实际应用具有一定的指导意义。 相似文献

在单相电力拖动装置中,使用单相永磁同步电动机替代传统的单相异步电动机是发展的必然趋势,然而目前单相永磁同步电动机的相关研究文献较少.本文基于简化的等效磁路、等效电路模型,利用电压迭代法编写出单相永磁同步电动机的设计软件SPPMSM v1.0,该软件的设计结果很好的满足了样机的设计技术要求.然后采用Ansoft公司的Maxwell软件,建立了单相永磁同步电动机(SPPMSM)的系统仿真模型.在所建立的模型基础上,对单相永磁同步电动机的基本特性和运行性能进行了仿真研究.仿真结果可以用来指导这种新型电机的设计. 相似文献

ABSTRACT Although neodymium-iron-boron (Nd-Fe-B) magnets have high-energy product with suitable magnetic and physical properties for applications in electrical machines, the design of permanent magnet (PM) motors is a complicated problem due to their complex geometries and PM material characteristics. This paper initially compares various PM motor geometries and describes their PM material outlay, armature reaction and mechanical integrity. By the employment of appropriately located air slots to reduce the armature reaction in conjunction with flux enhancement arrangement without detracting from its mechanical integrity, a new rotor geometry for a high-field high-speed PM synchronous motor is proposed. Computer-aided electromagnetic calculation and graphical evaluation are employed for the design and optimization of the proposed PM motor. An idea of ‘computer job delegation’ is proposed and implemented within the computer system to provide full utilization of each computer's capabilities as well as parallel operation of the design and optimization process. The proposed rotor geometry and design philosophy have been implemented to design a 3.2 kW PM synchronous motor. 相似文献

This paper presents a method for estimating the machine parameters of a synchronous motor. The presented method is equally applicable for a wound field synchronous motor, synchronous reluctance motor, or permanent magnet (PM) synchronous motor, both the interior and surface-mount types. The method works particularly well for machines having a significant amount of space harmonics, such as synchronous reluctance and interior PM (IPM) machines, where the harmonics are predominantly the slot harmonics. It is also well suited for surface PM machines operating under saturation, where the harmonics are saturation-induced. The presence of these harmonics makes the parameter identification difficult. Most of the methods presented so far in the literature have failed to properly identify machine parameters in the presence of space harmonics. In this paper, the machine parameters, identified by using a proposed algorithm, are compared with the finite element and the experimental results to demonstrate the effectiveness of the presented method. Both interior PM and surface PM machines are considered. 相似文献

For the calculation of torque in synchronous motors a local method is analysed, based on the Maxwell stress theory and the
filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap. By considering the space
fundamental field only, the method can efficiently estimate the average synchronous torque for a variety or motor topologies,
including concentrated winding designs. This approach employs an analytical filter for the Maxwell stress tensor and `frozen
permeability' technique. The proposed method is validated by comparison with FE results for several synchronous motor types:
interior permanent magnet motors, wound field motor, synchronous reluctance motor. 相似文献
