الوصف
This book focuses on the development of a thermal modeling approach for the design of electrical machines using analytical models, with an emphasis on machines with permanent magnets. It presents the methods used to determine the critical parameters of thermal modeling, and then introduces the complete thermal model that is developed and confronted with experimental results. The model is reported to provide good accuracy and is used to investigate how different topological variations affect thermal behavior. The book also examines and compares cooling strategies. Beyond the machine-level model, a related approach is proposed to simulate thermal exchanges between conductors in slots, highlighting the role of the random arrangement of conductors in the coil. The methods are designed to support optimization processes and improve thermal design and thermal management decisions.

design of electrical machines. It concerns more particularly machine with permanent magnets.
The methods used to determine the critical parameters of thermal modeling are presented first.
We then present the complete thermal model that has been developed and confronted with
experimental results. This model has very good accuracy and has allowed us to study the effect
of different topological variations on the thermal behavior. It was also possible to analyze and
compare different cooling strategies. This model can easily be integrated into an optimization
process to determine the maximum permissible losses of a given configuration, or to define the
cooling method to use. Based on the same principles, we proposed a new model to simulate the
thermal exchanges between the conductors in the slots. This model allows us to appreciate the
randomness of the arrangement of the conductor ...
