Based on previous investigations it is shown that the accuracy of online stator resistance monitoring of AC-machines fed by PWM inverters when using the superposition method suffers from dead time effects. A new and simple correction procedure is proposed to achieve high measurement accuracy without using temperature sensors. No additional hardware is required for this method. Experimental results are presented.
