Thermal

In the thermal settings you have two main possible choices:
  • Either you can define the temperatures of active components (Magnet and winding) to define the physical properties of the materials needed to run directly the tests without any thermal computation.
  • Or you can choose iterative process until convergence to perform electromagnetic computation coupled to thermal analysis.
Note: Setting a skew angle modifies the electromagnetic performance of the machine, including the losses.

For electromagnetic/thermal iterative solving, the losses are then considered as inputs of the thermal computation.

This means that in "Iterative" solving modes, the temperatures reached in the machine will change depending on the skew angle in input.

Note: The resistance network identification of a machine is always done without any skew angle.

This can bring some inaccuracy in the results for highly skewed machines.

Note: This test allows electromagnetic computations with coupled thermal analysis when both the following conditions are met:
  • The type of machine is Synchronous Machine with Permanent Magnets with Inner rotor.
  • Iterative thermal solving can be selected.
