Thermal modelling of line start permanent magnet synchronous motor

Abstract

A thermal model of the Line Start Permanent Magnet Synchronous Motor (LSPMSM) has been developed in this thesis to predict the motor's temperature rise under operating condition. The model utilizes the lumped parameter method and accounts for the heat generation within the motor. Simulation has been performed using MATLAB software. The thermal model can be used to optimize the design and operation of LSPMSMs. It can be used to predict the motor's temperature rise under different operating conditions and to identify the factors that contribute to overheating. This information can be used to design motors that are more resistant to overheating and to operate motors in a way that minimizes their temperature rise. The thesis also discusses about the scope for future research.
