摘 要：介绍了低速永磁直线同步电机（PMLSM）的基本结构，通过计算电机的参数，推导出电磁力表达式，最后得到低速永磁直线同步电机自起动的条件。通过Matalab仿真模拟电机起动过程，证明了自起动条件公式的正确性，为自起动低速同步直线永磁电机模型的真正建立奠定了一定理论基础。

Abstract: Introduced the basic structures of PMLSM,By means of the calculating the parameter of PMLSM,the expression of the motor’s force is inferred,the condition of self synchronizing was established.Finally,the starting of PMLSM was simulated using tool of Matalab Simulink，the correct of equation of self synchronizing condition is proved.The theoretic foundation of creating true self synchronizing motor model is established.
