【Abstract】This paper first describes the mathematical model of the permanent magnet synchronous motor. On the basis of the mathematical model of the motor,the identificationalgorithms of least square method and model reference adaptivearecombined to identifythe alternatingaxis inductance,stator winding resistance and rotor fluxof the motor online.The simulation results are analyzed.

【Key words】permanent magnet synchronous motor;model reference adaptive; least square method;parameteridentification
