摘要（英）：

The invention discloses a device used for identifying stator resistance of an induction motor and a device for implementing the method. For an induction motor in operation, estimated values of stator current and rotor flux of the induction motor are calculated by adopting a full-order flux observer of the induction motor according to stator voltage and stator current of the induction motor; and the rotor speed and the stator resistance of the induction motor are accurately calculated according to a stator current actual value, the stator current estimated value and the rotor flux estimated value of the induction motor.
