Description
Content

Overheated electric machines have a considerable impact on the active parts that constitute their life span. This is why it is important to know the distribution of temperatures that they undergo. Besides, the association of machines with the static converters became classic but contributes to the increase of losses. It is therefore just as important to determine their contribution to the system’s warming-up. 

The presented work describes an electric, magnetic and thermal analysis of a synchronous motor to permanent magnet and intended axial flux to cooling using the node method are elaborated. Results of simulations served to us validate models in various working conditions.
