Correct simulation of an electric motor will help reduce cost and increase efficiency. As motors continue to get smaller and work harder, excess heat is produced, and efficiency is greatly reduced. In some extreme cases, permanent magnets can even reach their limit and become demagnetized. Thermal management is a big challenge that needs to be analyzed early in the design process.
Simulating all aspects of a motor from electromagnetic fields and their loss distribution to structural integrity from thermal stresses will help with early design trade-offs and considerations. A simulation to show electromagnetic fields and the heat losses associated with them in Ansys Maxwell is the first step to perform the temperature analysis.
Heat losses are automatically mapped as a 3D time-averaged input to Ansys Fluent. These results will be analyzed to reveal the critical areas for thermal performance and optimize design for cooling. Under certain circumstances, when it is not enough to consider single physics, Fluent and Maxwell can be coupled: Fluent will simulate different cooling methods and pass the temperature information back to Maxwell. These values are used to adjust temperature-dependent material properties and perform corrections to the electromagnetic field, to pass back to Fluent for further evaluation.
