摘要 为了降低采煤机永磁传动系统中的电机定子振动,基于永磁体磁链模型,结合电机矢量控制建立考虑齿槽效应的永磁同步电机(permanent magnet synchronous motor,简称PMSM)模型。对包含永磁同步电机、齿轮传动系统、截割滚筒负载特性的采煤机永磁传动系统机电耦合动力学模型进行仿真,得到有载工况气隙永磁体径向磁通密度与电枢电流径向磁通密度。在此基础上,分析了定子硅钢芯与非晶合金芯的电磁力、磁致伸缩力、振动位移与共振点。定子为硅钢芯时,磁致伸缩力最大值达到电磁力的23.8%,在电机转速为393 r/min时出现激励频率18f_(m)引起的共振现象;定子为非晶合金芯时,磁致伸缩力相较于硅钢芯时明显增加,最大值达到电磁力的58.5%,在电机转速为288和433 r/min时出现激励频率18f_(m)和12f_(m)引起的共振现象,在实际使用中应加以注意。 In order to reduce the stator vibration in the permanent magnet drive system of shearer,a permanent magnet synchronous motor(PMSM)model considering cogging effect is established combined with motor vector control based on flux linkage model.The electromechanical coupling dynamic model is simulated including PMSM,gear transmission system and cutting drum load characteristics,and the radial flux density of air gap permanent magnet and armature current are obtained.On this basis,the electromagnetic force,magnetostrictive force,vibration displacement and resonance point are analyzed.The results show that the maximum magnetostrictive force reaches 23.8%of the electromagnetic force,and the resonance phenomenon caused by the excitation frequency of 18f_(m)appears at the motor speed of 393 r/min,when the stator is the silicon steel core.On the contrary,when the stator is the amorphous alloy core,the magnetostrictive force is significantly increased com‑pared with the silicon steel core,and the maximum value reaches 58.5%of the electromagnetic force.Further,when the motor speed is 288 or 433 r/min,there is a resonance caused by the excitation frequency of 18f_(m)or 12f_(m).This phenomenon should be paid attention to in actual use.
