【摘要】 横向磁通电机区别于传统径向电机,实现了定子齿槽的电磁解耦,具有高的功率密度,高转矩密度,高效率等优点。由横向磁通永磁电机取代传统电机,不仅节省原材料,而且节约能源。其主要适用于船舶、舰艇等需要低转速大转矩的电直驱场合。近年来广泛的受到了学者和企业的关注。由于横向磁通永磁电机相对结构较小,在高频率运行时,其内部的涡流损耗易引起较高的温升,所以对横向磁通永磁电机的涡流场计算与分析,削弱涡流损耗,是研究的重点之一。本文对于横向磁通永磁电机的研究分以下几个方面：首先,由于横向磁通电机内部磁场呈三维分布,所以利用Ansoft Maxwell软件三维静态场模块,进行电磁场仿真。针对定子齿宽、齿高等尺寸,电抗等参数进行研究。然后,对横向磁通永磁电机进行三维涡流场计算。利用Ansoft Maxwell瞬态场计算模块对样机模型进行仿真与分析。对空载和负载两种情况下的定、转子铁耗以及永磁体涡流损耗进行分析。结合电机基本原理对样机参数进行修改,对比各个方案下的涡流损耗,利用优化定子齿、永磁体分段等方法,降低涡流损耗,并且总结涡流损耗相关的规律。最后,对横向磁通永磁电机进行三维温度场计算。对电机进行假定以及等效处理,建立其等效模型,将其进行简化计算,减少计算时间并降低计算资源。然后对其进行剖分与计算,得出温度场计算结果并加以分析。更多还原

【Abstract】 Transverse flux permanent magnet motor(TFPM) is different from other types of traditional radial flux motor, which realize electromagnetic decoupling of the stator alveolar. It’s advantages is high power density, torque density and efficiency. The transverse flux permanent magnet motor replaces the traditional racial flux motor will not only save materials but also save energy. It’s mainly applicable occasion is in ship and warship which need low speed and high torque. TFPM has widely been the concern of scholars and business. Because TFPM’s structure is small, eddy current will cause high temperature rise when it’s in the high-speed operation. So calculation of eddy current loss of TFPM and reduce loss is one of important thing.This article for the TFPM’s research include three part:Firstly, as TFPM’s magnet field is three-dimensional distribution, Ansoft Maxwell 3D magnetic field module has been used, which to simulate the motor For the stator teeth shape, size, length and the air gap of other parameters research.Secondly, the eddy current field of TFPM is calculated by Ansoft Maxwell 3D transient calculated module. The iron loss of stator and rotor and eddy current loss of permanent magnet is calculated in no-load and load situation. The different parameter of program which include stator teeth size, permanent magnet section and so on is contrasted. Then modifying the program of motor design and summarizing the discipline the eddy current loss and iron loss.Finally, temperature of three-dimensional is calculated. Assumptions and the equivalent of motor has been done. Creating the calculated model, then simplified it for reduce the computation time and computing resources. Meshing and calculating the model to analysis the heat and temperature distribution of the motor.更多还原
