摘要：

The current study examines the thermal model of a permanent magnet motor (PMM) using the lumped parameter thermal technique to determine temperature changes in both steady-state and transient conditions. An investigation is conducted to examine the temperature fluctuations of the motor components over time under differentloads. The thermal model wasdeveloped using MATLAB code. The simulation results are used to analyse the thermal characteristics of the motor. The proposed thermal model's results are validated to the experimental findings investigated by published study. The optimization and sensitivity analysis are done using the response surface method (RSM) by design expert software. Results indicated that time and load have a greater effect on stator tooth temperature. The sensitivity analysis revealed that time has a bigger effect on all temperatures than the motor's load. All machine components clearly experience an increase in temperature as the load and time increase. Additionally, the method of multiplying points with a desirability of 0.998 is introduced, which exhibits optimal efficiency at the lowest temperature.
