【摘要】：永磁调速器是一种无接触磁力传动装置,由于其具有操作简单、软启动、软停止及隔离震动、允许对中误差、适应恶劣工况等优点,逐渐替代了现代工业领域中其它电力传动设备。目前,市面上的永磁调速器主要利用气隙长度或者导体转子与永磁转子轴向啮合面积的大小进行转矩与转速的传递,但是却忽略了轴向移动需要一定的轴向伸展长度,这将给工程中设备的改造及应用带来极大的不利。为解决这一问题,本文提出一种新型旋角式永磁调速器,不仅解决了工程使用中设备改造空间不足的问题,而且保留传统结构的高效率等实用性优点。(1)介绍旋角式永磁调速器原理,并对新型旋角式永磁调速器与传统永磁调速器磁特性做对比分析,在ansoft Maxwell中建立旋角式永磁调速器的二维模型,对其进行有限元分析,对其磁力线、磁密及涡流等磁特性进行分析;对传统型调速器进行三维有限元仿真,对比分析,得到新型旋角式永磁调速器在调速过程中稳定运行的范围大于传统型永磁调速器,为后续研究旋角式永磁调速器奠定基础。(2)给出旋角式永磁调速器的拓扑结构,对旋角式永磁调速器的模型进行分析,给出其磁路设计原理,并对旋角式永磁调速器进行可行性实验分析,验证本文给出这种新型调速器的理论可行性。给出根据弱磁区域配置导体铜环后内外气隙大小不相等问题的解决方案,实现导体转子在气隙中均等配置。(3)对新型旋角式永磁调速器样机进行设计,分别分析导体转子、磁轭材料、永磁体、气隙长度、气隙磁密等主要影响因素对转矩与转速传递性能的影响,优中取优的思想对各个尺寸进行选择,给出样机实物模型,对其性能进行研究,给出弱磁区域的配置。
[Abstract]:Permanent magnet governor is a kind of contactless magnetic drive device. It has the advantages of simple operation, soft start, soft stop and isolation of vibration, allowing center error, adapting to bad working conditions, etc. Gradually replaced the modern industrial field of other electric transmission equipment. At present, the permanent magnet governor in the market mainly uses the air gap length or the size of the axial meshing area between the conductor rotor and the permanent magnet rotor to transfer torque and speed, but neglects that the axial movement requires a certain axial extension length. This will bring great disadvantage to the transformation and application of the equipment in the project. In order to solve this problem, this paper presents a new type of rotary permanent magnet governor, which not only solves the problem of insufficient space for equipment transformation in engineering use. Moreover, the high efficiency and other practical advantages of the traditional structure are retained. (1) the principle of the rotary permanent magnet governor is introduced, and the magnetic characteristics of the new type of rotary permanent magnet governor and the traditional permanent magnet governor are compared and analyzed. The two-dimensional model of rotary permanent magnet governor is established in ansoft Maxwell, and the finite element analysis is carried out, and the magnetic characteristics such as magnetic force line, magnetic density and eddy current are analyzed, and the traditional governor is simulated by three-dimensional finite element method. It is obtained that the stable operation range of the new rotary permanent magnet governor is larger than that of the traditional permanent magnet governor in the course of speed regulation, which lays a foundation for the further study of the rotating angle permanent magnet governor.) the topological structure of the rotating angle permanent magnet governor is given. The model of the rotary permanent magnet governor is analyzed, the design principle of its magnetic circuit is given, and the feasibility analysis of the rotating angle permanent magnet governor is carried out, which verifies the theoretical feasibility of this new type of governor. According to the solution of unequal air gap between inside and outside of conductor copper ring in weak magnetic field, a new type of rotating angle permanent magnet governor prototype is designed, and the conductor rotor is analyzed separately. The influence of the main factors, such as yoke material, permanent magnet, air gap length, air gap magnetic density, on the torque and rotational speed transfer performance, is studied. The configuration of weak magnetic region is given.
