摘　　要：内埋式永磁同步电机(IPMSM)的弱磁运行受逆变器输出电压、电流以及电机本身可持续工作的电枢电流的制约,同时电机参数对其本身的弱磁能力也有影响。详细分析了这些影响因素,并且根据对这些因素的分析,结合电机数学模型和电压反馈调节策略建立IPMSM的弱磁控制策略,并用实验结果验证了算法的可行性。Flux-weakening operation of IPMSM is constrained by the maximum available output voltage and current of the inverter and the armature current rating in continuous operation. And the parameters of the IPMSM are also factors to constrain its flux-weakening region. On the analysis of these constraints, a flux-weakening control strategy based on the mathematical model of IPMSM and voltage regulation was proposed. And the results of experiment are presented to validate the performance of the proposed scheme.
