Taizhou Longxin Electronic Technology Co.，Ltd.，Taizhou，Zhejiang Province，318o2o China Abstrct：A control strategybasedonmulti voltage sequence injection is proposed to identify diferent motors forapplications where a single permanent magnet synchronous motor drive controler controls multiple motors.Theoreticalanalysis was conducted on the mathematical expressions of voltage and current after injecting aspecific voltage sequence into the motor，and experimental verification was carried out.Theexperimental results show that the proposed identification method has high accuracy and canaccurately identify two or more permanent magnet syn - chronous motors，effctively solving the problem of controlling multiple permanent magnet synchronous motors with a single motor driver， thereby improving the operating effect of permanent magnet synchronous motors.

Keywords： Permanent magnet synchronous motor; Voltage injection; Motor identification; Multi-motor control

商用永磁同步电机驱动器经常面临单个驱动器控制多种类型电机的控制需求[1-3]，但通常不同的电机具有不同的电阻、电感、磁链等电机参数，需要对电机进行辨识后再进行精确控制[4-5]。（剩余3438字）
