本文研究了一种互补型模块化直线磁通开关永磁电机,该电机的磁体和电枢绕组都放置在短动电机中,而长定子只由铁芯组成。该电机结合了直线永磁同步电机的高功率密度和直线感应电机的简单结构。特别适用于城市轨道交通等长定子应用。本文的目的是建立该电机的数学模型,以便对其进行控制。有限元分析的仿真结果验证了理论分析的正确性和模型的有效性。基于样机的实验验证了分析模型和有限元分析结果的正确性。
In this paper, a complementary and modular linear flux-switching permanent magnet (MLFSPM) motor is investigated, in which both the magnets and armature windings are placed in the short mover, while the long stator consists of iron core only. The proposed MLFSPM motor incorporates the high power density of a linear permanent magnet synchronous motor and the simple structure of a linear induction motor. It is especially suitable for long stator applications such as urban rail transit. The objective of this paper is to build the mathematical model for the purpose of control of this motor. The simulation results by means of finite-element analysis (FEA) verified the theoretical analysis and the effectiveness of this model. Both the analytical model and the FEA results are validated by experiments based on a prototype motor.
