摘要
为改善注塑机用永磁同步电动机的气隙磁密波形,降低振动和噪声,提出一种新的转子结构。设计了一台8极36槽永磁同步电动机,在转子铁心上适当打孔和开槽,借助电磁场有限元分析软件ANSYS Maxwell,建立电机模型,并对电机空载气隙磁场、齿槽转矩、电磁转矩及径向电磁力波进行了分析与计算,仿真结果表明,采用该转子结构可减少电机转矩脉动和气隙磁场谐波。样机试验结果验证了该电机设计的合理性。
To improve air-gap flux density waveform and reduce vibration and noise of the permanent magnet synchronous motor（PMSM） used in injection molding machines,a new type of rotor structure was presented.A PMSM with 8 poles and 36 slots was designed by proper drilling and slotting on a rotor core.The motor model was established by ANSYS Maxwell.The no load air-gap magnetic field,cogging torque,electromagnetic torque and radial electromagnetic force waves of the motor were analyzed and calculated.The simulation results show that the torque ripple,vibration and noise of the PMSM with the new rotor structure can be reduced.The test results of the prototype can meet the design requirements and verify the rationality of the design method.
