【摘要】：提出一种横向磁场磁通反向电机结构,电机中的永磁体与电枢绕组均位于定子侧,转子齿嵌入开槽的非导磁材料转子筒中,定转子铁心均可由硅钢片叠压制成。相比传统横向磁场电机,横向磁场磁通反向电机具有结构简单、加工方便的优点。介绍了电机的基本结构,阐述了电机的基本工作原理。利用傅里叶级数法推导了电机的反电动势、电磁转矩以及定位转矩的表达式。利用三维有限元方法,分析了电机的永磁磁链、反电动势、定位转矩和电磁转矩等基本特性。在其基础上研制一台样机并进行初步实验研究,实验结果与有限元结果相吻合,验证了理论分析的正确性。
[Abstract]:A structure of transverse magnetic flux reverse motor is proposed. The permanent magnet and armature windings are both located on the stator side. The rotor teeth are embedded in the slotted non-magnetic conducting material rotor tube. The stator and rotor cores can be made by the superposition of silicon steel sheets. Compared with the traditional transverse magnetic field motor, the transverse magnetic flux reverse motor has the advantages of simple structure and convenient processing. This paper introduces the basic structure of the motor and expounds the basic working principle of the motor. The expressions of the back EMF, the electromagnetic torque and the positioning torque of the motor are derived by using the Fourier series method. The three dimensional finite element method is used to analyze the basic characteristics of the motor, such as the permanent magnet flux, the back EMF, the positioning torque and the electromagnetic torque. On the basis of this, a prototype is developed and the experimental results are in agreement with those of the finite element method, which verifies the correctness of the theoretical analysis.
