Thermal Performance and Sensitivity Analysis of Permanent Magnet Motor: Theoretical Investigation and Optimization

Abstract:

The thermal model of a permanent magnet motor (PMM) is investigated in this study using the lumped parameter thermal approach to calculate temperature variation at steady-state and transient conditions. The temperature variation of the motor components over time under various loads is investigated. The proposed thermal model was constructed with the MATLAB code. The thermal characteristics of the motor are examined using the simulation results. The optimization and sensitivity analysis are done using the response surface method (RSM) by design expert software. It can be seen that increasing the load and time increases the temperature of all parts in the machine. Also, point multiplication with 0.998 desirability is presented, which has the best efficiency with the lowest temperature.
