【摘要】 为了便于长初级无铁心永磁直线同步电机的优化迭代，提高电机的求解效率，该文从电机的物理模型出发，以直线电机的多层线性模型为基础，通过引入矢量磁位，建立该种电机的数学解析模型。该模型首先提出了一种离散化的数学模型，对无铁心直线电机的弧形端部进行建模；然后，在上述模型的基础上，将计算得到的电枢电感等计算结果与有限元仿真结果与实验进行对比，验证所提出模型的准确性。最后，利用所建立的模型结合遗传粒子群多目标优化算法对电机进行优化设计。更多还原

【Abstract】 In order to facilitate optimization iterations of long primary Ironless Permanent Magnet Linear Synchronous Motor(IPMLSM) and improve the efficiency of solving the parameters of this motor, this paper established a mathematical analytical model with magnetic vector potential(MVP) based on the physical model of the motor and its multi-layer linear model. Firstly, in the primary part of the motor, apart from the inductance of the effective part of armature, the discrete mathematical model was used to model the arc end inductance of it. Then, comparing the the armature inductance of the motor calculated by the model with the finite element analysis(FEA) method results and test, the correctness of the proposed model was verified. Finally, the model was combined with genetic particle swarm multi-objective optimization algorithm to optimize the motor design.更多还原
