Abstract: Currently, the power density and torque density of permanent magnet synchronous motors are rapidly increasing, leading to a significant rise in losses and heat generation per unit volume in motor systems. This presents significant challenges for heat dissipation, temperature field modeling, and thermal management in motor systems. While there is a wealth of literature both domestically and internationally on the modeling of motor temperature fields and thermal management, the methods are diverse and lack systematic analysis and synthesis. To address this issue, the methods in recent domestic and international literature related to the analysis, modeling, and thermal management of motor temperature fields are reviewed and analyzed. The aim is to present the current state and trends in the development of motor temperature modeling and thermal management in a more systematic manner.
