Abstract:

The aim of this paper is to apply a mathematical model using a lumped parameter thermal method and to conduct experiment test to determine  he temperature distribution inside the induction motor to evaluate the thermal stability of the induction motor and to check whether the  sulation of the copper windings is sufficient at different operating conditions, and to find out the hottest element which has the main effect on the peration and performance of the motor. We found out from the thermal model analysis that the hottest element in the induction motor is the end winding and rotor bars, this is due to stator copper losses and rotor bars losses which depend on the stator current, the stator current can be increased by increasing the torque or by decreasing the stator frequency, which makes the temperature of each element to increase. The thermal model of the induction motor is validated by comparing the calculated temperatures of each element in the induction motor with the experimental results that obtained from through thermocouples connected to the computer via data logger, and the results showed that the accuracy of the proposed thermal model has uncertainities of about 4% ~ 6% .
