A new method to estimate the induction-motor stator and rotor resistance (Rs and Rr) and temperature (Ts and Tr) was proposed in this paper. Two signals with proper frequencies that yield high sensitivities of the terminal measurement to Rs and Rr at a given rotor speed are injected to the induction machine to estimate Rs and R r. The estimated Rs and Rr are then used to estimate Ts and Tr, respectively, according to the relationships between Rs and Ts, and Rr and Tr. Simulation and experimental work have been carried out to verify the proposed method. The proposed method can estimate both stator and rotor resistance and temperature with high accuracy, and the estimated Rs and Rr can be updated in real time. It does not require an additional hardware or a large amount of finite-element analysis (FEA) or experimental data for implementation
