Multiple Physics Simulation of an Electric Motor This project involves a comprehensive multiple physics simulations of an electric motor, combining structural, thermal and electromagnetic analyses to evaluate performance, reliability and operational safety under realistic loading conditions. CADs with the details necessary to be included depending on the analysis type and the simulation goals are prepared. For the static and frequency analysis of the shaft, shaft and rotor are kept in the model. For the cooling of the stator more details are needed to accurately model the heat generation and evaluate the cooling strategies. Therefore for the thermal simulation the CAD does not only include the coils, housing and stator but also the cooling channel and water jacket. Whereas for the electromagnetic analysis of the electric motor, all the details relevant for the magnetic field modeling are included. Such as the coils, stator, rotor and the surrounding environment, which is air region in this case. On the structural side, static mechanical analysis is performed to assess the shaft behavior under applied torque, ensuring structural integrity and acceptable stress levels. A modal (frequency) analysis of the shaft is also conducted to identify natural frequencies and avoid resonance during operation. For thermal performance, a conjugate heat transfer simulation is carried out on the water-cooled stator. This analysis captures heat generation in the windings, heat conduction through solid components and heat removal via coolant flow, enabling the identification of thermal gradients, hotspots and overall cooling efficiency. The electromagnetic analysis focuses on evaluating magnetic flux density distribution within the motor. From this, electromagnetic forces and torque generation were extracted, providing insight into motor efficiency, torque production and magnetic loading of components.
