Abstract:

Rotor and stator temperature is of concern in both short-term machine protection and in longer-term condition monitoring for large induction machines. Especially when operating with overload cycles, it is necessary to monitor rotor bars and stator winding temperatures to make sure that the temperature remains below prescribed limits. The purpose of this paper is to present a thermal monitoring technique, for induction motors, based on the rotor resistance identification. Experimental results are shown for a 4 kW four-pole squirrel cage induction motor.
