Abstract: The monitoring condition of an induction motor（IM） is critical to its stable and reliable operation.Temperature changes could be a useful indicator of the running motor.In order to monitor the temperature of the running motor,this paper proposes a feasible method to estimate the transient temperature of IM based on the double-resistance identification.On the basis of the resistances at the moment,the correction of resistances can firstly be realized by the model reference adaptive system based on the rotor flux.And then,the transient temperature of IM is adopted to obtain based on the loss model,which is calculated by the parameter above.On this basis,without correction,transient resistance value is able to be calculated by the basis of linear relationship between metal resistance and the temperature.The theoretical analysis and experiment results show the effectiveness and practicality of the proposed method in this paper.
